The GM Diet: Seven-Day Plan, Review, and Tips

The General Motors Detox Diet
I hate dieting. I mean seriously, it’s the worst. I like food—and not just food, but yummy, sugary, greasy, bad-for-you food. But when I realized it had been almost two years since my youngest son blessed me with bigger hips and the difficulty to look down and see my toes past my post-prego muffin top, I began searching for a way to get those pounds off.

Eventually, I came across a diet plan that promoted it’s ability to make you lose 10 to 17 pounds in a seven-day period. Despite the fact the diet seemed difficult, let’s be serious, 17 pounds in seven days is enough motivation for any of us to endure whatever this plan asks. So I decided to not only embark on the GM diet journey, but to write about my experience as well!

Does It Work? The Short Answer

Unlike Roger Cohen from the New York Times and other resources that promise you will lose 10-17 pounds in one week, I lost five pounds. However, I am not upset by that because I learned a lot about just how bad my eating habits were prior to this diet, and I learned a lot about self control. For a more detailed answer, including tips for how to make the whole experience more appetizing, see “My Day-by-Day Breakdown and Personal Review” below.

A Quick Overview of the GM Diet

The GM diet is rumored to have been developed by General Motors as an employee health plan. One overview to the diet reads:

The following diet and health program was developed for employees and dependents of General Motors, Inc., and is intended for their exclusive use. The program was developed in conjunction with a grant from the U.S. Department of Agriculture and the Food and Drug Administration. It was field tested at the Johns Hopkins Research Center and was approved for distribution by the Board of Directors, General Motors Corp., at a general meeting on August 15, 1985.

However, it is difficult to imagine a company telling its employees what to eat each day of the week, and with some digging, the New York Times has discovered that this backstory for the diet is an urban legend.

Nonetheless, the paper’s columnist Roger Cohen decided, “It’s a good diet, G.M. or no,” and reported that he lost 11 pounds during his week following the plan.

The diet dictates a different food each day (with a few strange aberrations, such as a baked potato with butter to start out your vegetable day), with each day’s food group accompanied by 10 glasses of water. Look at the chart below for a quick overview of what to eat each day.
