brainwashed in what way? I am open to any new information, but you don't seem to find it necessary to point out where I am wrong. you can choose to stay ignorant, but don't blame me for your laziness. name one thing I said that is incorrect and I will reassess my argument. I have done 3-4 days of fasting multiple times during my depression. it actually helped and allowed me to think much more clearly, listening to podcasts, meditating, reading about other people's experiences, studying research etc. and it contributed to me finding my way out of it. it might be a case of correlation/causation of effects, so I am not going to say it will help everyone no matter what, but our evolutionary development certainly supports those effects being real, just like say homoeopathy being a placebo treatment does not change the value of the outcome. sure, it can be dangerous applied in the wrong place and used to brainwash and exploit, but that can be said about almost anything.
if you consider this brainwashing, then you are looking for excuses to address reality. eating is often something people do in part to avoid dealing with their depression or other issues, and it makes things worse. I do intermittent fasting a few days of the week now, not because I have to, but because I just enjoy the payoff - the rewarding feeling of productivity and creativity while fasting and experiencing hunger, knowing there will be a delicious meal at the end (delayed gratification essentially) - which is actually a problem for me specifically, because it is in fact a little too effective relative to what my body needs, so I need to carefully moderate myself. I have almost no fat reserves and I have to eat extremely unhealthy just to maintain what would be considered a normal bmi, which shows how archaic the bmi system is. I would probably suffer from fatty liver disease, kidney failure and/or diabetes by the time I made it out of the underweight classification. so I have to balance those two sides of well-being. I already have a high risk of diabetes because I need so many carbs just to maintain my weight and carb digestion is wearing down my metabolism, which affects my long-term mental state. there is a reason why you are not very productive right after having a meal and when you eat all day (even just little amounts), your body never leaves that state. my dad has the same metabolism as me and is a vegetarian on top of that. so because of that, his diet was worse than mine which very likely contributed to him developing parkinson's (genetic predisposition from my grandma's side of the family) as grain, sugar and carbs in general make up an even bigger share of his diet and they cause an inflammatory reaction that affects dopamine production, but that's a whole different topic. my brother is studying this and he keeps me updated on the latest findings. it's not like I am just pulling this out of my ass based on anecdotal evidence. so I don't think I know a lot, I'm just reporting the knowledge and findings of other people, who actually do the research and they happen to confirm my experience. and I am not even the kind of person who would usually benefit from fasting, because I really don't have to do it for weight management. do whatever you want with that information, or don't.
