I found it very interesting, especially as I'm in the process of deciding on a diet and exercise program right now. Things get complicated for me because I have fibromyalgia, and any sort of even vaguely non-gentle exercise leaves me too tired and hurting to move. I had noticed, though, that while I might can only do 5 minutes of fast exercise, that slow, strengthening exercise such as weight-training or yoga does _not_ seem to hurt me nearly as badly, even if I'm doing quite a bit of it. So basically, five minutes of sweating and panting will have me cramped up and collapsing, but fifty minutes of steady, gentle effort won't. From what you've described, this seems to just be an exageration of a normal reaction, rather than something totally unheard of.

Opinions on carb-restricted or low-glycemic index diets? Those are what I'm looking at right now, primarily because they tend to make me feel better and have more energy rather than making me feel exhausted and sick.
