I have watched that documentary as well as many others in favor of plant based. I am following a plant based diet and I'm still losing weight, etc. My husband, who is trying to gain, is following as well and is gaining muscle much easier than he was doing all that protein. We both feel better, more alert. I don't have any digestive issues anymore. I'm quite regular as well. It's nice. In fact, he decided to eat a meal that was high in fat and had some animal protein in it today for lunch. He's currently sleeping, told me he felt really sick and gross. I told him his body doesn't want that stuff anymore. He won't be eating like that again. Lol
I started a thread in the Vegan/Vegetarian forum; Proteinaholic. Check it out. We're talking about what bariatric surgeon, Dr Garth Davis, has researched and found by science and evidence regarding animal protein and our diets. It's VERY interesting and just confirms to me I'm on the right path. His book is called Proteinaholic. You should check it out.
