In my never-ending quest to improve my health through diet I'm making a slow transition to this diet to test it out. I've previously tried the Wahls Diet (no effect) and a vegan diet (rapid crash). I've recently discovered I'm gluten intolerant and wonder if I may have problems with milk, which might have been a co-factor in my not getting on very well on my attempt at a vegan diet. A lot of people on the forums have emphasised that PWME need animal protein and I'd welcome views on this starch diet. Dr McDougall's view is that large populations eating traditionally (rice, corn, potatoes etc.) demonstrably thrive on high-starch (whole, not refined) diets. He's one of many people pointing out that the paleo diet doesn't take into account advances in archaeology that show that starch was a common component in human diet. The diet is basically: Primarily whole starch (complex carbs - grains, tubers, pulses, legumes) Some vegetables and fruits No animal products (meat, milk, eggs, fish) No 'free' oils separated from their plant source by pressing etc. (e.g. olive oil, corn oil) No fruit juices or dried fruits (too high in sugar) You just eat until you're not hungry, have many small meals rather than three big ones a day. You don't count anything - the nutrients take care of themselves. I've read his very interesting book: http://www.amazon.com/Starch-Soluti...id=1369482481&sr=1-1&keywords=starch solution But you can get the gist from this very interesting and entertaining YouTube lecture which lasts about an hour (he is an excellent speaker): He has a website with what looks like an active and well-run discussion board: http://www.drmcdougall.com/ Incidentally, this time I've decided to document exactly what I eat so that if this diet goes badly, at least in six months' time if I get some new indications of food I should avoid I can look back and see if I included it and if that might have torpedoed me. It's also helping me make a slow transition - I eat about 15 servings of food a day so if I swap one out a day I'll have made a complete transition in two weeks. I'm a bit scared of sudden change - I would have thought your microbiome would need time to adjust.
