The GM Diet is a fad diet that was supposedly developed by the General Motors Corp. as a means to help promote weight loss for its employees; however, GM says it knows nothing about the diet, according to a 2009 article published in the New York Times. It's a weeklong diet composed of mostly fruits and vegetables with some meat that promises a 10-pound to 15-pound weight loss. While meat is part of the diet plan, there are ways to make it vegetarian. Consult your doctor before starting any weight-loss plan.
Vegetarian GM Diet
For the first four days of the GM diet you are eating only fruits and vegetables; however, on days five and six, you are encouraged to eat beef and vegetables all day. World of Diets says if you're a vegetarian, you can substitute brown rice for the beef on these days.
Beware of Fad Diets
No doubt you'll lose weight eating only fruits and vegetables for almost a week. However, when you lose weight quickly -- more than 2 pounds a week -- you're not losing fat, but water and muscle. These types of diets do not promote sustainable weight loss, and don't provide adequate amounts of dietary protein and some micronutrients. If you're looking to lose weight, and keep it off, you need to find a plan that helps you lose weight slow and steady, at a rate of about 1 pound to 2 pounds a week.
