So I just watched, Alone Season One and Two. Those guys ate a lot of food in most cases. I can’t help but think if they were keto adapted that they would have a easier time. Most appeared to be carb loaded going in and then they suffered as they had a learning curve on getting food.
Anyway, I love watching those types of shows, Naked and Afraid and what not. It’s amazing how much weight they lose. I’d love to see results on how many keep the weight off. I would guess they gain it back in spades, if they go back to eating FDA guidelines.
