I'm going to post a link to a website here, and all I'm going to say is this: When I follow this man's advice to the letter, or as closely as I'm able to given my income and circumstances, I feel good and my weight drops at least slowly. There is also a definite effect on my blood sugar for the better, and at this time in my life it's either get that under control or lose a leg or two. If I get a good amount of physical activity the weight drops even faster. I'm overweight because I punish myself with food, habitually make horrible choices, and get extremely overindulgent when I'm depressed - NOT because this guy is wrong so far as I can tell. And once more, for emphasis, if you are not comfortable switching to a completely meat-and dairy-free lifestyle these guidelines are
not all-or-nothing. The idea is just to get as close as possible and you will notice a difference in how you feel.
Read through the info and make your own informed decision; it really is a treasure trove of information, refutations of the positions of those who stand to make scads of money from ill people, and helpful ideas.
