I would strongly advise against the General Motors Diet.

First of all, it's an urban legend. The diet claims that it was developed by General Motors to help it's employees lose weight safely. The truth is that General Motors Corporation had nothing to do with this diet, never prescribed it to any of it's employees, and does not endorse, nor ever has endorsed, the diet.

It's a hoax.

Second, the GM Diet itself is a classic fad diet that relies on extreme calorie restriction and the elimination of entire food groups on some days and an over-emphasis on certain food groups on other days. It is also nutritionally unbalanced.

Like many fad diets, it makes scientifically unproven claims about "detoxification" and targets weight loss in excess of 10 lbs a week, which is not only unhealthy, but probably unattainable.

You would lose some weight if you ate this way, but the short duration of the diet and its bizzare food combinations would probably result in you gaining most -- if not all -- of the weight back after the diet is complete.

I would consider making permanent changes to the types of food you eat and get more regular exercise. These two things will allow you to have lasting fat loss and feel healthy and energized, versus following a quack diet created by someone in their basement with no training in nutrition.

Best of luck!
