Improving VO2 Max: A Look at Vegetarian and Vegan Athletes
This is the first of a three
video series about exercise. Do plant based diets have an
impact on fitness? What are the best times
to workout? Watch the series to find out. "Improving VO2 Max: A Look
at Vegetarian and Vegan Athletes" In my video about comparing vegetarian
and vegan athletic performance, endurance, and strength, I discussed
a 2020 study that found that vegan athletes—even though
they were significantly older— had significantly superior
aerobic capacity and endurance, lasting 25 percent longer on a
time-to-exhaustion cycling test.
The question is why? One potential mechanism
that could explain the greater level of endurance performance
in vegans may be a higher amount of carbohydrate intake, which could
lead to better endurance performance through higher
muscle glycogen storage. Other potential mechanisms
that may explain the better endurance performance in vegans could
be due to the anti-oxidant and anti-inflammatory
profiles of their diet. Maybe it’s even their hearts. Yet another study showing superior
VO2 max in vegan athletes, meaning superior
aerobic capacity: this time they also
did echocardiograms, looking at their hearts
in real-time using ultrasound, and the lower relative
wall thickness and better main ventricle
systolic and diastolic function in the vegans are most
likely positive findings. Now wait a second. Given
the higher VO2 max reached by the vegan athletes, maybe
they were just better trained than the nonvegan athletes,
and that’s why their hearts looked like they
were working better. However, the weekly training
frequency and running distance were similar in both groups,
suggesting benefits even with the same
amount of training. So, it’s important to educate
healthcare professionals; so they don’t try
to discourage a vegan diet and may even want to consider
telling folks implementing an exercise training
program to give it a try.
But you don’t know if it
has the same kinds of effects in nonathletes, until
you…put it to the test. A vegetarian vs. conventional
calorie-restricted diet: the effect on physical fitness
in response to aerobic exercise in patients with
type 2 diabetes. Diabetics were randomized
to the same caloric restriction, the same exercise, but just
vegetarian versus nonvegetarian. They provided all the meals
so they could ensure compliance and closely monitored
the exercising. VO2 max increased by 12 percent
in the vegetarian group, significantly better than in
the non-vegetarian group who didn’t significantly
improve at all. Maximal performance increased
by 21 percent in the vegetarian group, again, significantly better than in
the non-vegetarian group who didn’t significantly
improve at all. In other words, the results indicated
that more plant-based diets led more effectively to
improvement in physical fitness than less plant-based diets, after the same aerobic
exercise program.

Here’s what the graphs look like: significantly better power
output and aerobic capacity in the group that was randomized
to a vegetarian diet. It seems that those eating vegetarian were able to better burn off carbohydrates compared
to nonvegetarians, and had better insulin sensitivity, both markers of improved
metabolic flexibility, meaning the ability
to switch back and forth between burning sugar and fat. Besides physiological
mechanisms, there may also be
psychological factors. They observed reduced hunger
and reduced feelings of depression in the vegetarian group
which may have given them a more positive attitude
towards exercise. Here’s the psychological data. Those randomized to eat vegetarian
had a greater improvement in quality of life and mood. They felt less constrained,
meaning the calorie restriction didn’t seem as burdensome; they had less disinhibition, meaning less tendency
to binge and overeat, along with maybe
less feelings of hunger.
Not to mention the superior effects
of a vegetarian diet on body weight, glycemic control,
blood lipids, insulin sensitivity,
and oxidative stress. Wait, better body weight? I thought they were given
the same number of calories. Yes, both diets were isocaloric,
the same calories, yet just eating meat-free led
to significantly more weight loss— about six pounds more;
more waist loss, a slimmer waist; lower cholesterol, of course;
and less superficial fat, meaning the external jiggly fat; and most importantly, significantly
more visceral fat loss, the most metabolically
dangerous deep belly fat.
Same calories, yet more
loss of body fat. And not surprisingly,
better control of their diabetes. All in addition to leading
more effectively to improvements
in physical fitness..

Treating Asthma and Eczema With Plant-Based Diets
"Treating Asthma and Eczema With Plant-Based Diets" Twenty patients with allergic eczema were placed
on a vegetarian diet for two months, and their disease scores, covering both
subjective and objective signs and symptoms were cut in half, similar to what you see
using one of our most powerful drugs. The drug worked quicker, within about two weeks, but since side effects may include kidney failure
and cancer the drug is considered a class 1 carcinogen,
the dietary option may be preferable.
But this was no ordinary vegetarian diet. This was an in-patient study using
an extremely calorically restricted diet. They were practically half fasting, so we don't know
which component was responsible for the therapeutic effect. What about using a more conventional plant-based
diet against a different allergic disease, asthma? In Sweden, there was an active health movement that
claimed that a vegan diet could improve or cure asthma. Bold claim. So in order to test this, a skeptical
group of orthopedic surgeons at the University Hospital followed a series of patients who were
treated with a vegan regimen for one year. Patients, participants had to be
willing to go completely plant-based and they had to have physician-verified asthma of
at least a year's duration that wasn't getting better, or even getting worse despite
the best medical therapies available. They found quite a sick group to follow.
Thirty-five patients with long-established hospital-verified
bronchial asthma for an average duration of a dozen years. Of the 35 patients, 20 had been admitted to the hospital
for acute asthmatic attacks during the last two years. Of these, one patient had received acute infusion therapy a total
of 23 times during the period, which is like an emergency intravenous. And another patient claimed he had been brought
to the hospital 100 times during his disease and
on every occasion had evidently required such treatments. One patient even had a cardiac arrest during an asthma
attack and had been brought back to life on a ventilator,
so we're talking some pretty serious cases. They were on up to eight different
asthma medications when they started. They were each on an average of 4.5 drugs
and still not getting better. Twenty of the 35 were constantly using cortisone, which
is one of our most powerful steroids used in severe cases.

So basically fairly advanced cases of the disease,
more severe than the vegan practitioners were used to. Still, how'd they do? Eleven could not stick to the diet for a year. But of the 24 that did, 71% reported improvement
at four months and 92% at one year, and these were folks that had not improved at all
over the previous year before changing their diet. Concurrently with this improvement, the patients
greatly reduced their consumption of medicine. Four had completely given up their medication altogether,
and only two weren't able to at least drop their dose. They went from 4.5 drugs down to 1.2,
and some were able to get off cortisone. Some said that their improvement was so considerable
that they felt like ”they had a new life.” One nurse had difficulty at work because
most of her co-workers were smokers, but after the year she could withstand the secondhand smoke
without getting an attack, as well as tolerating other asthma triggers. Others reported the same thing. Whereas previously they could only live in a clean environment
and felt more or less isolated in their homes, they could now stay out without getting asthma attacks.
And it wasn't just subjective improvements. There was a significant improvement in a number of clinical variables, including most importantly, measures of lung function, vital capacity,
forced expiratory volume, as well as physical working capacity, as well as a significant drop in sed rate,
and IgE, which are allergy associated antibodies. Bottom line, they started out with 35 patients who had
suffered from severe asthma for an average of 12 years, all receiving long-term medication, 20 including cortisone, were subjected to vegan food for a year, and in almost all cases medication was withdrawn or drastically reduced,
and there was a significant decrease in asthma symptoms. Despite the improved lung function tests and lab values, the placebo effect obviously can't be discounted
since there is no blinded control group, but the nice thing about a healthy diet
is that there are only good side effects.
Their cholesterol significantly improved, their
blood pressures got better, they lost 18 pounds, so from a medical standpoint, I figure why not give it a try?.

IQ of Vegetarian Children
"IQ of Vegetarian Children" Okay, so the bronze goes to
hormonal genital meat malformation. The silver goes to a study
on IQ and vegetarianism. First, let me share
a little background. We’ve known for
nearly 30 years that vegetarian children
test smarter than omnivorous kids. First shown in a
1980 study by Tufts University, the IQ of vegetarian children was found
to be about 16 points above average. And their “mental age” was a year
ahead of the rest of their classmates. Of all the veg kids,
the vegan kids appeared the smartest. The pediatricians and psychologists
knew the veg kids were bright, but the researchers noted
that they were puzzled that they were
so much superior. Which came first, though?
The chicken or the egg? Well, for the vegan kids,
neither, perhaps. But were they smart
because they were vegetarians, and therefore getting
all that good nutrition— or did they become vegetarian
because they were so smart? Well, the mystery has
finally been solved—I guess. Those fantastic Brits followed
8,000 kids for 30 years. Measured their IQ at age 10,
then came back 20 years later and asked which of them had
become vegetarian during that time. Their findings? Higher scores for IQ
in childhood are associated with an increased likelihood
of being a vegetarian as an adult.
Smart people
evidently eat vegetarian. They even quote Benjamin Franklin
saying vegetarian diets result in “greater clearness of head
and quicker comprehension.”.

Update on Vegetarian Stroke Risk
"Update on Vegetarian Stroke Risk" Healthy plant-based diets
have been associated with lower all-cause mortality,
up to a 34 percent lower risk of death from any cause over an average
of an eight-year period, just being in the top
versus bottom quarter of healthy plant-based consumption. If sustained, that could translate
into more than four extra years of life. A meta-analysis of a dozen studies
prospectively following more than a half a million people
for up to 25 years similarly found significantly lower
heart disease and overall death rates among those eating more plant-based. No surprise,
a systematic review concluded since plant-based diets
may arrest or even reverse our number one killer—
cardiovascular disease. Those eating wholly plant-based
tend to be significantly slimmer with lower LDL cholesterol, triglycerides,
blood sugars, blood pressures, significantly less inflammation,
and less carotid artery wall thickening (a sign of atherosclerosis measured
via ultrasound in the neck), as good as what you see
in endurance athletes who’ve run an average of 50,000 miles,
which is like twice around the globe. And changes in risk factors
can happen fast, as evidenced by results
from one to three-week ad libitum (eat-all-you-want)
plant-based “kickstart” programs.
For example, the results from the first
few hundred participants of the at-home
15-day Jumpstart program created by the nonprofit Rochester
Lifestyle Medicine Institute were recently published. On a whole food plant-based diet,
obese patients lost an average of 7 pounds without controlling portions
or counting calories or carbs. Diabetics saw their fasting blood sugars
drop 28 points. Those with LDL cholesterol
over 100 experienced a 33-point drop (comparable to some statin drugs), and hypertensive individuals
experienced a 17-point drop in systolic blood pressure,
which is better than drugs, and all within just two weeks! Studies dating back nearly 40 years
show those eating meat-free diets also have improved blood “rheology,”
meaning fluidity or flowability, which may play a role
in cardiovascular protection.
Subsequent interventional studies putting
the cross-sectional findings to the test, show that switching people
to a plant-based diet can improve rheology measurements
within three to six weeks. But might the blood of vegetarians flow
a bit too well, though? In 2019, a study of thousands
of British vegetarians called EPIC-Oxford found that they were at higher risk
of hemorrhagic (bleeding) stroke. They had such a lower risk
of heart disease that they still had less
cardiovascular disease overall (and a half dozen studies show no overall
increased risk of stroke mortality), but why the greater stroke incidence? I suggested it might be vitamin B12
deficiency, which can lead to excessive levels
of a stroke- associated metabolite called homocysteine
which is normally detoxified by B12.
This is thought to be the reason
why vitamin B12 supplementation can improve artery function
of vegetarians. Vitamin B12 supplements
or fortified foods are critical for anyone eating plant-based,
but my 12-part video series on vegetarians and stroke risk
triggered by the 2019 publication was all in vain. It turns out vegetarians don’t appear
to have higher stroke risk after all. In response to the EPIC-Oxford results,
researchers around the world scrambled to see if the findings
were merely a fluke. In 2020, UK Biobank, a massive study
following more than 400,000 volunteers, confirmed that vegetarians
had lower cardiovascular disease rates and importantly,
no increased incidence of stroke.
And two studies from Taiwan
found vegetarians had significantly
lower risk of stroke. Following tens of thousands
of vegetarians for up to ten years, they only had about half the stroke risk
compared to nonvegetarians (including a 64 percent lower risk
specifically of hemorrhagic stroke). By 2021, Harvard researchers
had finished and published their analyses of the 200,000+ participants
of the Nurses’ Health Study, the Nurses’ Health Study II, and the Health Professionals
Follow-Up Study. They too found no increased stroke risk
for vegetarians and indeed a decreased risk of stroke among those eating
healthy plant-based diets. A meta-analysis putting all the studies
together found that indeed the EPIC-Oxford data appeared
to be a fluke after all, finding, if anything, a lower risk
of stroke in a subgroup analysis. A 2022 systematic review
concluded that vegetarian and low-animal product diets are associated with a significantly
lower risk of bleeding strokes, a significantly lower risk
of clotting strokes, and a significantly lower risk
of total strokes across the board..

How to Lower Blood Pressure Naturally with Lifestyle Changes
"How to Lower Blood Pressure
Naturally with Lifestyle Changes" Fasting has been practiced
for thousands of years, but only recently have we
started to put it to the test. I did a previous video series
about the studies on using fasting for weight loss back in the ‘70s. Was it safe? Was it effective? But what about fasting for treating
and preventing other diseases? One of the side effects noticed
in the early weight loss studies was a consistent fall in blood pressure,
so much so you typically have to stop taking blood pressure
medications while fasting or else your pressures fall too low. Once you start eating again,
your pressures go back up, but remarkably, not as high
as they were before.
But, of course, it depends on
what you start eating again. For example, a case report
of a woman who used fasting to drive her rheumatoid
arthritis into remission. Systolic blood pressure
started up around 170 despite multiple blood
pressure medications was put on a whole food plant-
based diet for eight weeks. That dropped her down
from 170 down to 130, off of all medications
before starting the fast, and then normalizing down
to 110 after the fast. But is that just because
of all the weight loss? She lost 22 pounds on the fast,
and 27 pounds on the plant-based diet. So yeah, it’s extraordinary to drop
your pressures from 170 to 110, but that was after
losing about 50 pounds. We’ve known for decades
that any kind of weight loss can lower blood pressure. Even minor weight loss can lower
blood pressures in obese persons, even if they remain
significantly overweight. But most of the drop in blood pressures
with severe caloric restriction happens within the first two days,
before significant loss of body fat; so, it may also be a reduction in
the fight-or-flight stress hormones, like adrenaline and noradrenaline
both before… and after exercise, after just two weeks of just a
few hundred calories a day.
So, that may be one reason
why a very-low-calorie diets have been found useful in
lowering blood pressures even in those for whom blood
pressure medications fail: the changes in those hormones. But, low calorie diets also
tend to be more plant-based; so, there’s fiber and potassium-
rich foods, less saturated fat. Even just adding fruits and vegetables
to the diets of hypertensives can lower their systolic blood pressure—
the top number—by 7 points. That’s the kind of blood pressure
improvement you might get losing 10 pounds, just by eating
more fruits and vegetables.

And, if you combine that with
a drop in meat consumption, not only doubling fruit and
vegetable intake but combining that with trying to slash
saturated fat and cholesterol, you can cut pressures by 11 points. What else can we do? Restricting alcohol intake in regular
daily drinkers can drop you 5 points. So, let’s keep track here:
alcohol restriction can drop your systolic
blood pressure 5 points, losing ten pounds can drop you 7,
as can just eating the recommended 8 to 10 servings of
fruits and vegetables a day. Regular aerobic exercise for
at least 3 months can drop you 9…. So, let’s add that on to the chart. Combine the fruits and
vegetables with meat reduction and you can drop it 11. Blood pressure medications
can have side effects, but on their own can
drop pressures by 15 points.
What about cutting down on salt? Note in the other diet study they
kept the sodium levels the same. Cut sodium enough and it
can edge out drugs at 16: the drugs 15, sodium restriction 16. Is that the best we can do with diet? Put people on a purely plant-based
diet, even one moderate in sodium, and you can drop
hypertensives by 18 points even after 9 out of 10 reduced
their blood pressure medications or stopped them entirely,
all within just 7 days. That’s pretty impressive. Now, what if you took that
same diet, but added fasting? 37 points! We’ll review that study
and others like it, next..

Plant-Based Protein: Are Pea and Soy Protein Isolates Harmful?
"Plant-Based Protein: Are Pea
and Soy Protein Isolates Harmful?" So, are these plant-based
burgers healthy or not? And the answer is…
compared to what? Eating is kind of a zero-sum game;
every food has an opportunity cost. I mean, every time we
put something in our mouth it’s a lost opportunity to put
something even healthier in our mouth. So, if you want to know
if something is healthy, you have to compare it to
what you’d be eating instead. So, for example,
are eggs healthy? Compared to a breakfast
link sausage? Yes! But compared to oatmeal?
Not even close. But look, sausage is considered
a group 1 carcinogen. In other words, we know consumption
of processed meat causes cancer. Each 50-gram serving a day,
that’s a single breakfast link, was linked to an 18% higher
risk of colorectal cancer. So, the risk of getting colorectal
cancer eating one link a day is about the same as the increased
risk of lung cancer you’d get breathing secondhand smoke all
day living with a smoking spouse. So, compared to sausage,
eggs are healthy, but compared to oatmeal,
eggs are not.
So, when it comes to Beyond Meat
and Impossible Burger, yeah, they may be better in
that they have less saturated fat, but, hey, you want
less saturated fat? Plant-based meat
alternatives are no match for unprocessed plant foods,
such as beans or lentils. And a bean burrito or lentil
soup could certainly fill the same culinary niche
as a lunchtime burger. But if you are going to
have some kind of burger, it’s easy to argue that the
plant-based versions are healthier. There is a sodium issue, and
it’s not that much, if any, lower, in saturated fat, since
they use coconut oil, which is basically just
as bad as animal fat; there’s not much
advantage on that front.
Though the total protein is
similar across the board, does this matter? Or Is there any
advantage to eating plant protein over animal protein?
Let’s look at the association between animal and plant
protein intake and mortality. In the twin Harvard cohorts,
following more than 100,000 men and women over decades, “…after
adjusting for other dietary and lifestyle factors, animal
protein intake was associated with a higher risk [of] mortality,
particularly [dying from cardiovascular disease], whereas
higher plant protein intake was associated with
[a] lower all-cause mortality”, meaning a lower risk of dying
from all causes put together. So, “replacing animal protein
of various origins with plant protein was associated
with lower mortality”, especially if you’re replacing
processed meat and egg protein, which were the worst. But when
it comes to living a longer life, plant protein sources beat out
each and every animal protein source. Not just better
than bacon and eggs, but better than burgers, chicken,
turkey, fish, and dairy protein. Together with other studies, these
“findings support the importance of protein sources for the
long-term health outcome and suggest plants constitute
a preferred protein source compared [to] animal foods.” Why? Well, unlike animal protein, plant
protein has not been associated with increased levels
of the cancer-promoting growth hormone IGF-1, for example.
Now, soy protein is similar
enough to animal protein that at high enough doses, like eating
two Impossible Burgers a day, you may bump your IGF-1. But the only reason we care
about IGF-1 is cancer risk, and if anything, higher soy
intake is associated with a decreased risk of cancer. For example, a recent systematic
review and meta-analysis found that soy protein intake was
associated with a decreased risk in breast cancer mortality;
we’re talking “a 12 percent reduction in breast cancer death
[associated with] each 5-gram-a-day increase in soy protein intake.” But the high soy groups
in these studies were on the order of
more than 16 grams a day, associated with a
whopping 62% lower risk of dying from breast cancer. More than 10 grams of soy
protein a day may be good, associated with cutting
breast cancer mortality risk nearly in half, and getting
more than 16 grams a day may be better, which is like
one Impossible Burger a day. But we simply don’t know what happens at consumption levels far above that.

Plant protein has also been
linked to lower blood pressure, reduced LDL cholesterol, and
improved insulin sensitivity. No wonder “substitution of
plant protein for animal protein has been related to a lower incidence of cardiovascular disease
and type 2 diabetes.” Indeed, 21 different studies following
nearly a half million people, and “high… animal protein
intakes [were] associated with an increased risk of [type 2 diabetes], whereas [even just] moderate
plant protein intake is associated with a decreased
risk of [type 2 diabetes].” OK, but these were just
observational studies. They all tried to control for other
dietary and lifestyle factors, but you can’t prove cause-and-effect,
until…you put it to the test. The “Effect of Replacing Animal
Protein with Plant Protein on [blood sugar] Control in
Diabetes: A Systematic Review and Meta-Analysis of
Randomized Controlled Trials.” Even just switching out about
a third of your protein from animal to plant sources
yielded significant improvements in long-term blood sugar control,
and fasting blood sugars, and insulin. You can do the same thing
looking at cholesterol. Here’s a systematic review and
meta-analysis of randomized controlled trials on the effect
of plant protein on blood fats.
And indeed, swapping in plant
protein for animal protein decreases LDL cholesterol,
and this benefit occurs whether you start out at high
cholesterol or low cholesterol, whether you’re swapping out
dairy, or meat, and eggs, and whether you’re swapping in
soy or other plant proteins. We’ve known about the beneficial
effects of soy on cholesterol going back nearly 40 years, but
other sources of plant protein can do it as well. Yeah, but
we’re not swapping beans for beef. These products are mostly
just isolated plant proteins, mostly pea protein isolate
in the case of Beyond, and concentrated soy protein
in the case of Impossible.
If you just isolate out
the plant proteins themselves are you still going to get benefits? Yes, surprisingly. Check it out. Interestingly, the researchers
concluded, that they did not find a significant difference between
protein isolate products and whole food sources, “suggesting
that the cholesterol-lowering effects are at least, in part, attributable to the plant protein
itself rather than just the associated nutrients.” So, it’s not just because
plant protein travels with fiber or less saturated fat. Plant proteins break down
into a different distribution of amino acids; and so, it’s
like if you give people arginine, an amino acid found
more in plant foods, that alone can bring
down people’s cholesterol. And even plant protein concentrates
used in these products aren’t pure protein, retaining
a few active compounds such as phytosterols and antioxidants, which also can have beneficial effects..

Plant-Based Diet for Treating and Reversing Stage 3 Kidney Disease
"Plant-Based Diet for Treating and
Reversing Stage 3 Kidney Disease" Is it possible to ameliorate
chronic kidney disease using a whole food,
plant-based diet? In my last video
on kidney disease, I talked about how randomizing
people to cut just around 10 grams of protein from their
daily diet could cut their risk of dialysis and death
by a whopping 77%. That was cutting protein
across the board. But while animal-based
protein ingestion — meat, dairy, and egg white
protein ingestion — promotes an acidic environment
in the kidneys, inflammation, and stresses the kidneys to what's
called hyperfiltration mode, plant-based protein can be
alkaline-producing and anti-inflammatory and contain
kidney-protective properties. So, what if you have kidney patients
eat a plant-dominant low-protein diet, abbreviated adorably as PLADO,
I guess for plant-dominant. If you fashion up a plant-based diet
index score where you get points for healthy plant foods and get points deducted
for eating animal foods, those with serious kidney disease
with higher scores were found to have lower systemic inflammation.
But does that actually translate
into living a longer life? Apparently so. Even a 10% increase in the
proportion of plant-based protein was associated with a significant
reduction in all-cause mortality. Even just eating more servings of
fruits and vegetables, like two a day compared to two a week,
is linked to living longer. Without fully functioning kidneys, there are concerns about
phosphorus and potassium overload, though, on a plant-based diet. But the phosphorus in plant-based
foods is not as much of a problem as the phosphorus additives
in processed and animal foods. And the risk of potassium overload
from plant-based diets appears overstated and not supported
by the evidence.
But you don't know about
ameliorating chronic kidney disease using a whole food, plant-based
diet until you put it to the test. Here's a case report of a 69-year-old
man with type 2 diabetes, high blood pressure, and
stage 3 chronic kidney disease, resulting in elevated phosphorus
and potassium in the blood, Interested in changing his diet
to improve his medical condition. That's my kind of patient! He was on 12 different medications,
eating a diet that may actually be slightly better than
the average American: some whole grains and beans, but then his doctor advised to try
eating whole food, plant-based.
So, oatmeal with fruit and flax,
beans and greens, whole wheat spaghetti and
veggies, fruit as snacks. Counselled to eat as much as he
wanted from whole healthy foods; no carb counting, no calorie counting,
no portion size restriction — improving the quality of food rather
than restricting the quantity of food. He adopted the whole food,
plant-based diet, packed with carbs, yet rapidly reduced his insulin
requirements by more than 50%, and subsequently saw
improvements in weight, blood pressure,
and cholesterol. Because eating healthy
can have such a rapid effect on improving your body's
insulin sensitivity, immediate adjustments
in insulin dosing were made. Within four days, his insulin dose
was able to be reduced from roughly 210 units of insulin
a day down to 70 units daily, and an oral blood-sugar lowering
medication had to be stopped due to rapidly improving blood sugar. He also was able to stop his
carvedilol, the hydrochlorothiazide, amlodipine, sitagliptin
within the first two months due to improving blood pressure
and blood sugars.

His insulin dose was
steadily titrated downward. His pravastatin dose was cut in half,
and he lost about 50 pounds. Okay, so what happened
to his stage 3 kidney failure? He was no longer in
stage 3 kidney failure! Doctors watching this will understand
what all these numbers mean. Here's a graph of his GFR, which
is a measure of kidney function, declining for years before shooting
up after he started eating healthy. He experienced an increase
in estimated GFR of 73%, suggesting that the improvement
in estimated kidney function was greater than what would be
expected from weight loss alone.
For example, lose about 60 pounds
from bariatric surgery, and you only get
about a 12 to 15% boost. Bottom line: for individuals
with chronic kidney disease, especially those with obesity,
hypertension, or diabetes, a strict, all-you-care-to-eat
whole food, plant-based diet may confer significant benefit. I mean, apart from the
kidney-specific outcomes, overall mortality is significantly
lower among kidney patients who eat more plants. And that's critical because most
kidney patients don't even make it to dialysis because they die first, most often from
cardiovascular disease.
Let's hear from the patient. "At the outset, it seemed like
this was going to be a difficult and restrictive way to eat, but I began feeling different
almost immediately and we had to decrease
my insulin after ONE day. It seemed like almost overnight I had
more energy than I'd had in years. Weight I'd been trying to lose for
a decade began dropping off. As the weight came off, I felt lighter,
and more able to move my body again. This lifestyle change has been
the greatest gift I've ever received. I am off most of my medications,
I've lost over 70 pounds, and I've regained control
over my health. I feel empowered
by this lifestyle change, and I finally feel like I'm
in charge of my health, not just an unlucky victim shuffling
from one specialist to the next.
My only regret was that
I didn't know about this sooner.".

Why I am no longer vegan (after 6 years)
After six years of living and preaching the vegan lifestyle I no longer follow a vegan, plants-only diet. Instead I've started eating meat again and I thought I'd share why. I've wanted to share this with you all since I started eating meat again around four months ago but I've been procrastinating on making this video partly because I wanted to see how my body responded to the introduction of meat again and also because I've been a little afraid of how it would be received. My decision to eat meat was something I didn't make lightly. I've quietly pondered about it for some time and have been researching the benefits of eating meat for over six months now. It all started after I listened to a podcast by Dr Mark Hyman which was, 'Why Vegan Diets May Not Be Good for Your Health,' featuring Jayne Buxton. This took me down a rabbit hole as it questioned everything I believed in as a vegan; that eating a plants-only diet would improve my health, how it was better for animal welfare, and how it would help in saving the planet from from the excess carbon being produced from the animal agriculture sector.
Suffice to say, having the integrity of your beliefs questioned isn't easy. But, I believe that it is important to reevaluate certain ideas we assume are facts every so often as information changes all of the time, particularly in the health and nutrition sector. Six years ago I decided to go vegan after watching a few documentaries on veganism, such as Cowspiracy, What the Health, and Forks Over Knives. This was based on a one-sided view of the story around animal agriculture and its impacts on human health and the planet. Since then I've come to learn that while a plant-based diet may work for some people it is definitely not for everyone (as with any diet, there is never a 'one-size-fits-all' approach to eating) and while others have noted an improvement in their health (which can be misleading at first and I'll delve into this further later), I did not. So here is a little about why I'm no longer vegan and why I started eating meat again and other animal products after six years of eating only plant foods.
I went vegan back in 2016 after watching the documentary Cowspiracy and learning that animal agriculture was supposedly worse than the whole transportation sector in terms of carbon emissions. I say 'supposedly' now because since then I've learnt that it isn't true. This claim was based on a 2006 report made by the Food and Agriculture Organisation of the United Nations where they said that 18% of global greenhouse gas emissions were from livestock making it a greater emitter than the global transportation sector. The Food and Agriculture Organisation actually reduced down their 18% number after receiving challenging allegations revising the new number down to 14.5%. However the damage had already been done entrenching the idea that the climate crisis is largely a result of global agricultural farming. I was one of those people who wholeheartedly believed this. If you'd said to me six years ago that I'd be making this video I would have never believed it. Being vegan has really helped shape the woman I am today and I've learnt so much from the experience. It's helped me to learn as well that changing your beliefs and ideas around something is okay.
I've learnt to keep more of an open mind about things that I may disagree with, as my way isn't always the right way. Plus, veganism was a stepping stone into living a more sustainable, eco-friendly life for me. It led me on the path to where I am now where I make all of my own products and live as consciously as I can. Another reason why I went vegan was because of the acclaimed health benefits. Again, this has turned out to be misleading. the nutrients found in plant foods are less bioavailable meaning they're less absorbable for our bodies than those found in animal sources. And, what's more, some nutrients can only be found in animal foods such as pre-formed vitamin A, B12, D3 and K2, haem iron, taurine, carnosine, creatine, CLA, EPA and DHA. This means that in order to receive these nutrients you have to supplement, which is what I did. But even still, synthetic forms of these nutrients found in supplements or fortified foods still aren't up to par with those naturally found in food sources, as the body recognises these forms of nutrients more than our man-made versions and these vitamins and minerals are absorbed more easily when they come from food.
Plant foods are also high in carbohydrates. When you remove animal fats and protein from the diet you need to replace it with something else and that something is often carbs. Carbohydrates are broken down by the body into a sugar known as glucose and when that sugar enters the bloodstream the pancreas responds by producing insulin which allows glucose to enter the cells in the body and provide them with energy.
Over time the insulin receptor sites in the cells become less sensitive, meaning more insulin must be produced to do the job. Eventually cells stop responding to that insulin altogether leading to a condition known as insulin resistance a precursor for type 2 diabetes. While meat is more fatty that's a good thing. The idea that animal foods raise cholesterol has been proven to be false, as fat doesn't make you fat essentially. It actually does the opposite. High-fat low-carb has been found to help reduce inflammation as the body uses ketones for energy rather than glucose. And while cholesterol has been labelled as "bad" it's a really essential component in the body. Cholesterol is a critical building block for many of the hormones that help with proper functioning of the body, it plays a part in the immune system, and is significant in the proper repair and maintenance of tissues in the body.

Without cholesterol we would have no cell renewal, and no life. Plant foods also come with an array of anti-nutrients like oxalates, lectins and phytic acid which prevent nutrient absorption and can cause inflammation in the body when consumed in large amounts. A common phenomenon that often occurs with many new vegans is the 'vegan honeymoon,' a phase which can last for months or even years. It's where people find they're initially helped by going vegan but after an extended period of time, sickness starts to set in. And this is what happened to me. In my experience, my health problems started about four years after going vegan. I became very fatigued and found it extremely difficult to lose weight, which as a young woman in my 20's I thought was very unusual.
I had also developed leaky gut, something I never experienced before and suffered with a candida overgrowth from all the sugary fruits and high carbohydrate foods I was eating. Plus, I felt hungry all the time. I experienced many nutritional deficiencies, the most common ones being zinc, iron, and B12. These deficiencies left me feeling tired and fatigued most of the time, no matter how much sleep I got. I was also losing hair and not just a little, a lot which really scared me. To help with my fatigue my naturopath suggested that I start including eggs in my diet (as I refused to eat any other animal foods at the time) and I noticed a huge improvement in my mental health, fatigue and nutritional deficiencies. A year later I went vegetarian and a year after that I started a pescatarian diet which quickly switched to an omnivore diet focusing mostly on animal foods as I could keep to a high-fat low-carbohydrate regime which I found worked best for my body.
For me when I went vegan the resounding message that was being conveyed was that as an individual, the single biggest thing you could do to help the planet and reduce your carbon footprint was to eat a plant-based diet. However this isn't necessarily the case. While we think eating plants will help the planet what we don't see are the impacts crops are having on the health of the ecosystems. Soy for example is a main staple in a plant-based diet and while it's estimated that 75% of the soy grown is used for animal feed, the feed given to livestock is mostly made up of the by-product and crushed soybean matter left over from extracting the soybean oil. So even though more soy by weight is consumed by animals the more soybean oil that is consumed by humans directly impacts the soy that must be grown to accommodate the demand, driving deforestation and damaging the soil via the use of monocropping and chemical fertilisers. Industrial monocrop agriculture requires tillage, chemical fertilisers, pesticides, herbicides like glyphosate, insecticides, fungicides and other harmful substances which degrade the soil, killing microbes.
This leads to erosion of the topsoil, resulting in flooding, and can leach chemicals into our streams, rivers and oceans. The fact is that all foods impact the environment in some way and what we should be looking at is how the plant food or animal food was produced, rather than the food itself. We can start asking questions like was this food grown in a sustainable way, without artificial fertilisers that kill insects ravage the soil, and cause runoff into rivers and oceans? Was it grown locally, or has it been imported, travelling extensive distances to arrive on my plate? We as consumers hold so much power when it comes to the food industry.
We can help by buying our meat from suppliers who uphold high standards of animal welfare. This is what I've really committed to since transitioning to eating meat again. Ensuring that the food I eat has been produced in a humane, ethical and sustainable way. While grass-fed and finished beef or pasture-raised chicken, pigs, and poultry are more expensive than the standard feedlot meat, the value is worth it as you really do get what you pay for. Plus it also means that everybody wins in this scenario. The animals, the farmer, the customer, and the environment. I firmly believe that we have a responsibility to properly care for the animals on which we depend on.
It does not give us freedom to treat them any way that suits us. We must put respect and compassion at the heart of animal agriculture. Animal welfare matters and should be built into the strategies we use to farm. I hope you got something out of this video whether you are or aren't vegan. Thank you so much for watching. I hope you have a wonderful day and I'll see you soon again..

Do Vegans Have Lower Bone Mineral Density and Higher Risk of Osteoporosis?
How does a vegan or vegetarian
diet affect bone density, and what other factors contribute?
Watch the video to find out. "Do Vegans Have Lower Bone Mineral
Density and Higher Risk of Osteoporosis?" Osteoporosis is estimated to affect
200 million people worldwide. Literally meaning "porous bone ,"
osteoporosis is a disease characterized by reduced bone
formation, excessive bone loss, or a combination of both,
leading to bone fragility and increased risk of fractures. And bone mineral density is the
most robust and consistent predictor of osteoporotic fracture. What can
we eat to boost our bone density? Well, we know that increased
consumption of plant foods is associated with increased
bone mineral density. There's an extensive range of
micronutrients and phytochemicals packaged within plants that can be
powerful promoters of bone health, so healthcare professionals
should be encouraged to advise the increased
consumption of plant-based foods, particularly in mid-life, irrespective of the clients
underlying dietary pattern, meaning no matter how
much meat or junk they eat, adding more healthy plant
foods may help prevent the development of osteoporosis. On the other hand, a more
animal-source nutrient pattern has been associated with
a higher risk of fractures, suggesting that a more animal-based
diet is related to bone fragility.
So one would expect less osteoporosis
in those eating plant-based diets, but you don't know
until you put it to the test. "The Incidence of osteoporosis
in vegetarians and omnivores ," the first study published
nearly 50 years ago, and the density of the bones
that were measured was significantly greater in the
vegetarians than the omnivores. In fact, the average bone densities
of the vegetarians in their '70s was greater than the densities
of the meat eaters in their '50s. Bottom line, these results suggest
there's less likelihood of vegetarians developing osteoporosis in old age. Turns out, though, that
the researchers screwed up. DEXA scanning, which
is what we use now, didn't come online until the 1980s. So the researchers were
just using regular x-rays and they confused the readings,
such that darker bones on the x-ray got a higher score, but that
actually means less bone, so their conclusion should
have been the opposite of what they claimed.
So vegetarians had
worse bone mineral density. Fast-forward about 40 years,
by which time nine studies had been done on thousands
of individuals, and all in all, the results suggest that vegetarian
diets, particularly vegan diets, are associated with lower
bone mineral density, but the magnitude of the association
is clinically insignificant, meaning the difference was so small as to not
really matter out in the real world, reinforcing the fact
that vegetarian diets have no clinically detrimental
effect on bone health. And it is important to note
that the findings of lower bone mineral density didn't fully
control for key confounding factors, such as for differences
in body weight. We know that people who are
obese have stronger bones. Why? Because they're weight lifting 50 pounds
all day, every day, and maybe 100 pounds. If you walked around with a
100-pound backpack every day, your bones would grow stronger, too.

That's how you build strong
bones: weight-bearing exercise. So people who weigh
more have denser bones. And vegetarians, and especially
vegans, have such low rates of obesity that no wonder, on average they
would have lower bone density. The researchers didn't
take weight into account, but if the difference they found isn't
even clinically significant, who cares? As of 2009, the answer to the question, "Is vegetarianism a serious risk
factor for osteoporotic fracture?" the answer was no. Vegetarianism
is not a serious risk factor. By 2018, the latest meta-analysis
on veganism, vegetarianism, and bone mineral density,
was up to 20 studies, involving tens of thousands
of participants, and, again, lower bone mineral density
was found in studies of vegetarians and vegans
compared to meat eaters. The researchers conclude that
vegetarian and vegan diets need to be appropriately
planned to preserve their bones. But wait, did they account
for the obesity thing? No, they did not. They just used what are
called crude risk ratios, meaning no adjustments for
confounding factors like weight, so they didn't control for things
like age, smoking, obesity, exercise, and so their results
are really uninterpretable.
But no one had gone through
the trouble of going back through all those studies and making
the proper adjustments until now. The title gives it away: "Differences
in Bone Mineral Density between Vegetarians and Nonvegetarians
Become Marginal when Accounting for Differences
in Body Size Factors." Yes, bone mineral density values
were significantly lower among vegetarians
than among nonvegetarians, just like is the case
with nearly every study on bone mineral density
and excess body weight. But forget clinical significance;
these differences even lost statistical significance
upon adjustment for body size factors, suggesting that lower
bone mass among vegetarians is in larger parts explained by their
lower BMI and waist circumference. Thus, it's not so much the composition
of the diets of vegetarians and vegans as much as it is the fact that
they become so much slimmer.
Now a small but statistically
significant difference remained for total lower spine density,
a difference of 0.03. This was dismissed as having little
clinical relevance, but is that true? If you look at the reproducibility
of bone mineral density measurements in daily medical
practice, you can see how if you do repeat tests back-to-back,
there's some scatter in the measurements, and
so a significant difference really has to be more
than the inherent variation. And indeed, expressed as
the smallest detected difference, you really need a bone
mineral density disparity of at least 0.05 at the spine before it can be considered
a significant change, and so indeed, there does appear
to be little clinical relevance. However, even if vegetarians
and vegans basically have the same bone density
at the same weight, everyone who is skinny
is at risk. Low BMI is a risk factor for
fractures, so all persons in a low body weight category
consuming any kind of diet should be monitored
for osteoporosis.
