The science is pretty clear and supports what is said in this article.
I changed my diet from "normal" to carnivour (which basically is a form of low carb) and had lots of improvements in my health even thought I had normal weight. I had ulcerative colitis for 20 years and all symptoms was gone within 6 months, also verified with a rectoscopy.
I also had great improvements in mood and motivation by taking vitamin-d and for cramps/sleep by taking ZMA (Zinc for testosterone, Magnesium for cramps).
Can recommend the books Deep Nutrition and Genius Foods, the latter is probably more accessible.
Also recommend following @Mangan150 on twitter.
Isn't animal product a lot worse for the environment than plant-based food? Long term the world has to move towards consuming less animal product, not more.
Eating food that make you unhealthy is not a choice for me, and I am happy for those have better life with different diets. For those who have problems, I can recommend trying this out for some months and see if it helps you.
I wasn't suggesting eating food that's bad for you, but rather if there are plant-based protein sources (such as legumes) that can be used as (at least partially) a replacement for meat.
Wait does the carnivore diet actually work? I remember Joe Rogan and Jordan Peterson discussing this diet, and Peterson was widely ridiculed for it (example https://www.theguardian.com/food/2018/sep/10/my-carnivore-di...). Has the consensus on it changed?
Problem is though, anecdotal evidence does not correct for various things, for example regression to the mean.
The improvement may purely coincidental with the change of diet, or the chosen diet.
Hence we need studies and not anecdata to judge, if something works.
As an individual you should still be allowed to test put various things.
No, as an individual you aren't allow to preach afterwards that anyone can do this.
But you can say: this helped me.
As an individual you don't have to care if it is s result of placebo, your particular gut biome or even magic. If it works it works.
Be happy, write that it helped you, don't write, just don't be annoying about it ;-)
Also the currently top comment https://news.ycombinator.com/item?id=25819790 summarize it neatly, something like: as far as we know all diets work for weight loss as long as we control for calorie intake (but read the original I linked to).
