all very interesting, but you have to wonder about a placebo effect, or that in fact it's just another repackaged low carb diet. it's not wheat per se that's to blame, but simply the calories in them. the placebo effect can be due just to ppl following the diet and watching what they eat much more closely. sure you don't want to be scoffing down tons of cakes, breads and pastries every day, but you can easily avoid high carb foods in general. the premise that dwarf wheat is causing all the problems is also highly suspect and not really backed up by any evidence.
the negative 1 star reviews on amazon give you an idea of how flawed dr davis' reasoning is, he often completely reverses the findings of studies, e.g. in one 81% of ppl on gluten free diets had gained weight over a period of time.
what really scares me is the amount of clever, glib verbalising that has been conducted on demonising wheat, the number of people praising the diet to the heavens, etc, all based on what seems to be very poor science by someone claiming to be an MD. just like the last 10 fad diets. what ppl seem to really want, apart from a new diet religion to worship, is the opportunity to stop moralising about their weight and blame a single, simple external item for all their woes. it's not their appetite, gluttony, greed, lack of self control contributing to their weight, it's that wheat!
Further claims some 'reviewers' make about massively reducing their weight, triglycerides and blood pressure actually seem outright fraudulent and too good to be true. All in the interests of selling a book for 10 bucks.
