What do you do for protein? I can’t imagine it’s practical for the long term. I still think weightwatchers is the healthiest and you do have to control portion size for meat but vegetables and fruits are pretty unlimited(other than corn potatoes etc)
One of my best friends who is a major carb lover lost an astonishing 160 pounds in 18 months on weight watchers, and he has kept it all off, too-he was morbidly obese at 345, and had been for years-he says it has changed his whole view of food.
I’d worry about getting enough protein, too-early humans ate plenty of meat with their green stuff, and didn’t have much in the way of flour from grains till they started milling them.
I’m guessing that not too many Neolithic humans were overweight, either-it is when you bleach, smash, and process the food in some way that you get few nutrients and a bunch of useless calories....
