The General Motors, or GM, diet plan claims that by following its program, you can lose between 10 to 17 lbs per week! Impossible, right? According to the program, by eating specific water-based foods, your body goes through a detoxification process that prepares it for clean eating habits.

There is no online proof that the global car company was behind this diet craze; however, many reports credited General Motors with the program.

It is thought that the GM diet plan began in the late 1980s when the company devised the program along with the United States Food and Drug Administration and the United States Department of Agriculture to help its employees lose weight and be healthy.

It is also called The Cabbage Soup Diet and The Sacred Heart Diet.

What Is The GM Diet Plan?

The General Motors diet plan is a seven-day eating program that focuses on preparing the body for a healthy lifestyle. Its goal is to flush out all of the toxins and prepare your digestion system to process clean, good foods.

The goal? To burn more fat and calories than the body is consuming, therefore, using the stored body fat for energy. In turn, by losing weight, a person will become more comfortable in their own body and have more energy as they eat healthy food.

How Does the GM Diet Plan Work?

Since the main structure of the GM diet plan is based on water intake and water-based foods, your body undergoes a detoxification process in the seven days.

After the seven days, the idea is that you will feel much better with a cleaned-out system and decide not to eat the processed foods that may have made you feel sluggish and ill.

The foods in this plan are vegetables, fruits, brown rice, or soup, along with milk and six to eight glasses of water each day. These foods, and the amount of water, promote faster digestion which makes you feel full faster.

This will prevent you from over-eating. As well, by drinking enough water, your body will not retain water.

Oddly enough, most forms of the GM Diet Plan only focus on the food with no specific exercise plan. There are some variations that do take exercise into consideration and outline a regiment based on the daily energy food sources.

GM Diet Plan: Foods to Eat and Avoid

To achieve up to a 17 lbs weight loss, the combination of low-calorie fruits and vegetables with complex carbohydrates and water must be consumed accordingly.

It is important to avoid certain foods on specific days. During the seven days, there is to be no consumption of alcohol, use of salad dressings, and no more than a teaspoon of oil used during the cooking process.

Depending on the source, the GM Diet Plan allows for some substitutions and will call for either brown rice or the special GM soup. We have provided the following day-to-day plan along with the recipe for the soup for the best results.
