Reminds me that I need to study the impacts of a vegan diet in the science literature to understand how aggressively I should be pursuing it. The times I’ve lived on a near vegan diet, I feel quietly better in lots of little unexpected ways. Happy to chase books or links if people have them lying around.

A friend of mine chose a “macrobiotic” diet 35 years ago. Apparently practitioners have conferences, too, Or so ive been told.

I had to stop after 6 months because my testosterone dropped so much (serious, blood test confirmed). Felt way better for the first few months, then slowly lower energy and not like myself. Eventually realized more vegetables is good, but nailing is protein wise on true vegan diet is very very hard.

It is absolutely not "very hard." It is challenging at first because like anything else, the startup costs of new habit formation can be high. But tofu, soy milk, seitan, tempeh, lentils, and many other plant protein sources are highly available and easy to cook with once you try. Been at it for a few years myself and at this point, it's extremely easy. I take protein shakes when working out, just like I did when I ate animal products.

Everyone is different, but if you weren't actually able to hit protein macros then I think that's a skill that isn't too hard to improve for most people (if they have a decent reason for wanting to go vegan in the first place).

I’ve been vegan for 14 years. Protein is not very very hard, unless you have multiple dietary restrictions on top of plant based. Which, if I can be frank, tend to be self imposed when people complain about this to me after dabbling in plant based.

Correlation is not causation, especially in a sample of 1, the plural of anecdote is not data etc etc. Protein is easy, just eat some beans and rice, tofu, tempeh etc. You can't just take the diet you had before and subtract things and expect it to work, you have to substitute. Make sure to get B12, D and maybe omega 3 and creatine either as supplements or fortified in foods, and get your levels checked every year or so.

I've been vegan for 15+ years, and I'm willing to say there are zero health benefits over a healthy omnivorous diet. The people who find one are misattributing it. It's not that vegan is healthier, just that what they were doing before was decidedly unhealthy. For a lot of people going vegan is the first time they actually think about what they eat, read labels etc, which is where most of the benefit comes from.

I am vegan except for fish, and find it works really well. Sardines are awesome!

A good term for that is pescatarian - as eating fish is neither vegan nor veg!

I'd say their description is fair. We don't have a word for vegan+fish. Pescetarianism includes eggs, milk, etc.

So they're precisely vegan, with fish.

That is absolutely wrong.

There is no gray area when it comes to veganism. Just because there is no word for that diet, does not mean you can just twist the definition of vegan for your convenience.

You could easily just say your a pescatarian who doesn’t eat dairy or eggs, and that would be more correct.

Sorry for not being perfect like you. For ethical reasons, I do not consume dairy or meat (except for fish). The vegan community should be more open to other perspectives, especially when someone is actively making an effort towards reducing harm.

Vegan Puritanism is totally antithetical to our collective goal of reducing animal suffering. Rather than being motivated by the prospect of claiming moral superiority, our goal should be to help the animals.

Then you would be twisting the meaning of pescatarian. There is no gray area when it comes to pescatarianism.

Except veganism is not a diet, but an ethical framework. The diet is a consequence, not the definition.

Dr. Michael Greger's "How not to die" is interesting.

That book is highly-biased in favor of veganism. Greger is very controversial. Any mention of him ought to also acknowledge this. Also, he wears a lab coat but doesn't see patients, which is weird AF.

Highly misleading title. They make you really dig up linked paywalled papers before you see any methods to see what people actually ate.

The methods say people were allocated to vegan versus "high meat consumption" foods, with participants free to choose their diets. The only restriction was you had to "try" to increase intake if losing weight, and "try" to decrease intake if gaining weight. (i.e. only isocaloric per basal rate, not across the board). Then the linked studies hint heavily that the vegan group tended towards less protein but more fibre, and roughly equal carbs (fat is not mentioned!!). Which at the very least shows the diets were not "equivalent bar for meat", let alone for "moderate" (i.e. potentially healthy) amounts of meat.

So they're not comparing "healthy wholefood vegan vs healthy wholefood meat diets". They're comparing availability and behavioural tendencies towards dietary choices when aiming for a short term vegan diet versus when aiming for a short term diet characterised by excessive amounts of meat.

I honestly don't get why they do studies like this. It's a waste of time for everyone involved. It's almost like they're only after a headline extolling veganism, rather than actually useful comparisons that could lead to real, actionable dietary insights. Really, if anything, a supported conclusion here could even be that meat diets are likely healthier given sufficient fibre supplementation.

I can’t access the previous paper by the authors that contains details about the diets.

That being said, people don’t eat macronutrients, they eat foods. With equal caloric intake, a vegan diet is going to be higher in fiber and lower in fat and protein than a diet that includes meat. That’s probably part of why it’s healthy, but the reason for doing this study is to understand the mechanisms in more detail, rather than just claiming that one is better than the other.

When you say they should have supplemented fiber, you’re also implying they should have had less meat. According to the linked paper from this year, the meat-rich diet included at least 150g of meat per day, which is just a bit more than a chicken breast or a single burger patty. Probably in line with what many expect from a balanced meal.

> When you say they should have supplemented fiber, you’re also implying they should have had less meat

Why? This is a non-sequitur. As are the other assertions in my opinion. You can have meat based diets rich in fibre (e.g. the mediterranean diet), and you can have vegan diets completely devoid of them (e.g. living off McDonalds plantburgers for the rest of your life).

The problem is this conflating of veganism, which at its heart is an ethical movement, as a nutritional one. So designing studies that intentionally blur this line isn't doing anyone no favours.

If I see a study comparing vegan junkfood against the mediterranean diet where the vegan diet still comes on top, I'd change my tune. But the reverse scenario, i.e. comparing meat-based diets of a nature that most people would intuitively consider unhealthy anyway (i.e. not necessarily because of the meat) against vegan diets which most people would intuitively consider healthy anyway (i.e. not necessarily because of the veganism) provides zero useful evidence.

And if I were to make a dietary choice for ethical reasons, I would much more appreciate insights coming from impartial science over an echo chamber, academic or otherwise.

Both pure vegan and pure meat camps claim to have scientific evidence that it works, which make me question if change is what the body responds to. From personal experience, eating less often and fasting does seem to improve things like brain fog, indigestion etc.

People going vegan or going pure aktins or whatever have the most important thing in common, they are actually thinking about what they eat, reading labels and generally making conscious decisions about food.

That’s a false equivalence, not all evidence has the same quality. I don’t think there’s any doubt across serious scientists that meat intake should be limited for positive health outcomes.

We need to collectively evolve as a species past intensive industrial animal confinement. To think, we can be more compassionate and don't need to sacrifice our health, and may in fact be able to live healthier!

> the participants were randomly assigned to two groups: 24 followed a vegan diet for four weeks, while 24 followed a diet particularly high in meat.

This may be correct technique for a small-n, short-duration study.

But don't expect the results to be applicable to typical non-vegans.

Living to 100 is overrated anyways.

   As if this planet will even be worth living on if climate change continues to go unchecked. Or if humanity will even exist after the inevitable mass extinction event

Do you look down on murderers and rapists? Or if you think that analogy is too strong, what about people who beat their children, which was considered normal and expected 60 years ago.
