Couple of days ago I was watching naked and afraid, this guys body pretty much shut down and he had to be medivaced to a hospital. They were only 4 or 5 days into the show? The doctor said the problems were from a lack of vitamins and minerals. The guy said he ate something like 5,000 calories a day. I kind of figured he was going to have problems going from 5,000 calories a day to almost nothing.
The guy on the show came across as a great person. He was friendly and had a wonderful attitude. However, it seemed like his body did not react well to be taken out of a certain setting.
The vast majority of the public are use to eating certain foods. Then that all stops in one day. People are spoiled to getting food right when they want it, and then that all stops. There are all kinds of videos on youtube of people getting in fights because McDonalds was out of a certain food.
