Dawn Jackson Blatner is the creator of The Flexitarian Diet. She is a dietitian and she wrote the book: The Flexitarian Diet: The Mostly Vegetarian Way to Lose Weight, Be Healthier, Prevent Disease, and Add Years to Your Life. You can have the benefits of a vegetarian diet without having to follow all of the strict rules. Being a flexitarian is a more flexible, more realistic way to be a vegetarian. Studies have shown that nearly two out of three vegetarians don’t, or can’t, do it full-time.
