Diet Delusion

Very good research, although too much Michael Mooreing (constantly repeating over and over). One problem though; if carbs were not essential, perhaps even the reason why we evolved and our cousins are in the trees, why did our sialic acid metabolism change so much? It must have given us an evolutionary advantage to eat more carbs. Becoming more dependent on carbs meant being able to switch between protein heavy and carb heavy diets (perhaps in warm and cold seasons) with little difficulty. Diseases like CHD and diabetes are chronic, but we have to remember they (usually) hit us later in life after we've had a chance to pass on our genes so to speak. I realise the book is more directed at the diet industry and not dismissing this. However the call for more research is completely pointless. Look at agriculture; they can predict the yield of milk or meat per kilo of feed, right down to the last half kg, and can show how certain feeds will result in poor results yet they have never managed to pin down exactly where and why satiety occurs. What on earth makes anyone think we can do this with humans when cutting up and experimenting on ruminants hasn't revealed anything? It's a lot more complicated than "Eat this, eat that." But as a general rule of thumb, for a westerner (or someone who has taken up western ways of eating) who doesn't want to go on a diet and has no shortage of food, the advice in this book will help you lose weight
