This idea occurred to me several days ago, but i was in the middle of something and i didn't write it down.... Well, i'm reminded of it again now.
A favorite blogger has been on a VLC regime which, though she doesn't really like it, IS effective for weight loss. Unfortunately, the discomfort of it caught up with her and she's had to abandon it -- you HAVE to abandon an eating plan which makes you feel awful, no matter if others thrive on it or what.
When i read in "Strong Medicine" that 75% of Donaldson's patients did very well on his VLC regime, i didn't really spend much time thinking about the ones who did not. He didn't describe them in much detail, but left me with the impression that they just didn't care to comply. I'm rethinking that now.
Suppose they were like our blogging friend, who was doing the program determinedly, but had to give it up because it didn't agree with her physiology? Shall we use as a reasonable assumption that up to 25% of the population CANNOT do VLC, for thoroughly valid reasons? Perhaps their genetic backgrounds are such that they do not make the right enzymes to thrive on a diet providing very few carbohydrates. Perhaps their collections of gut-bugs aren't optimal for the situation. There could be all kinds of reasons, but the upshot is, VLC is just not right for them.
Makes good sense to me: NO single regimen is right for EVERYONE.
