General Motors has developed the GM Diet to help some of their employees lose weight and achieve an overall higher health. General Motors create the GM Diet along the FDA Food and Drug Administration and the US Department of Agriculture.
This approach to weight loss—also known as “the cabbage soup diet” and “the Sacred Heart diet”—has been popular ever since.
This plan is said to work on the principle that the foods you eat will burn more calories than the amount of energy (calories) they provide for the body to store in the form of fat. People have reported losses of between 10 and 17 lbs per week on this plan.
While there is no evidence online that concludes that General Motors is the actual source of this plan (see this op-ed piece in the New York Times), there are plenty of reports of success by people who have done the plan.
