If you’re looking to drop up to 15 pounds quickly, the GM diet, or General Motors Diet, may be something you want to try. Rather than restrict certain foods indefinitely, it tells you what foods you can eat on a certain day. Keep reading to get all of the details of this effective weight loss tool. 

About the GM diet

The GM diet is not a new diet. It first started in 1985 and, as the name implies, was developed by General Motors. The automobile manufacturer worked with the Food and Drug Administration and the United States Department of Agriculture to come up with an eating plan that would make employees healthier and raise their overall productivity. Many employees had amazing results, losing 10-17 pounds in a week. The diet is relatively easy to follow and uses real food that you can find anywhere.

How It Works

The GM diet focuses your diet on fruits, vegetables, brown rice, and chicken. You eat these foods or a combination of these foods on certain days. You also increase your water intake to at least 10 glasses a day to stay hydrated and feeling full. 


You should avoid alcohol for a few days before the diet schedule begins. The substance should be avoided completely while you are on the GM diet. Alcohol can make you retain water and prevent the detoxifying effect of the diet. Water helps boost your metabolism and eliminates water weight, naturally.

Benefits of the GM diet

Aside from the weight, you’ll lose, there are other benefits to the GM diet. People who have completed the program say they have more energy, feel more confident and just feel good.

Detoxes Your Body

Think of the GM diet as a juice cleanse you can chew. For seven days, you eliminate processed foods, fat and refined sugars from your diet. The good food and water flush out any remaining toxins and provide a wealth of nutrients. Detoxifying the body on a regular basis results in faster digestion and better elimination of toxins.

Improved Digestion

High-fiber foods, such as fruits and vegetables, improve digestion and are easily absorbed and eliminated by the body. The gm involves consuming large fruits and vegetables, resulting in a high-fiber diet. Water helps your body absorb nutrients. The combination of water and fiber makes eliminating waste easier and more complete. Low-fiber foods can linger in the body, making you feel sluggish and bloated.

Types of Food, Meal Plans & More

The GM diet can be done as a vegetarian or as an omnivore. As we mentioned earlier, the GM diet concentrates on certain foods on certain days. Let’s look at a typical week on the GM diet.

Day 1

The first day may be a challenge as your body adjusts to the new diet, On this day, you can eat only fruit. However, grapes, litchi, mangoes, and bananas are not allowed. All other fruit can be eaten as much as you’d like. Watermelon, oranges, limes, apples, pomegranates, melons and strawberries are particularly helpful at keeping hunger away. You can eat as many times during the day as you want. If you want to just eat melons the first day, you could lose up to three pounds.

Day 2

This day is for the vegetables. You can eat only vegetables that are raw or boiled. You can eat as much and as often as you would like. The GM diet allows you to start this day with a boiled potato and a teaspoon of butter. After that, potatoes and butter are off limits. To give your veggies a little more flavor, try adding dried herbs.  

Day 3

This day combines the foods of day 1 and day 2. You can eat fruits and vegetables as described above, just no potato and butter. You’ll get carbohydrates from the fruit. Drink at least 10 glasses of water to stay hydrated. Your cravings may flare up, or they may have disappeared. Keep going!

Day 4

Here’s where things get a little more interesting. You are allowed to eat up to 6 bananas and drink up to 4 glasses of milk. The bananas restore the sodium and potassium you need in your body.

Day 5

Here comes the protein. You should eat at least 500 grams or 17 ounces of chicken/lean meat and 6 tomatoes today. You should also increase your water today. All 3 of your meals should have chicken, about 6 ounces. For your morning and evening snack, you should drink water. No others foods should be consumed. If you do not like chicken, eat 6 eggs + 6 tomatoes that day. If you are vegetarian, you can have a cup of brown rice, tofu and cottage cheese.

Day 6

First off, congratulations for having the dedication to make it to the sixth day of the GM diet. On this day, you can eat chicken, all vegetables, except tomatoes, for all three main meals. You can also have a soup made with all vegetables, except tomatoes, for your mid-morning and evening snacks. For the vegetarian version of day six, you can eat cottage cheese instead of meat.
