Nothing like a little help from your friends. LOL! Thanks.

I think a couple of things were going on here. All that fiber threw his digestive tract into shock and quickly altered his gut flora - a hot toxic mess. In addition, huge amounts of cruciferous vegetables can block thyroid function - that could explain some of the fatigue both physical and mental. No protein intake for an otherwise healthy young guy - not good. Yes, the decline was pretty rapid. If he had not decided to do the exercising, things may have been different. Was there any way of knowing whether the activity level was normal for him or just done for the challenge? That would have drastically altered the outcome if it was not part of his normal daily routine. Interesting. Supersize Me only in reverse - and much faster.
