You took a lot of everything into this post about a topic a lot of people love to hate. A couple of the youtube videos/their providers I have seen myself in the past.

I lived Vegan for a while just to try out how I would react to it and it was okay. I was interested in a fruitarian lifestyle and it has a lot of interesting points too.

Overall, nutritional science feels like a seasonal thing where we learn about new/different things all the time. Couple years ago, fasting was considered wrong and dangerous by many, these days, it's popular.

I even lived on a vegan ketogenic diet for a while just to try it out. It was interestesting.

I am not saying that a certain style of living and eating is the correct one because I wouldn't know that 100%. What I can say s that upping the amount of vegetables has been overall good for me even though I have to find more ways to make me enjoy eating them.
