The original GM Diet Plan was developed by General Motors, with the help of the Food and Drug Administration and the United States Department of Agriculture, in 1985 for its employees. The idea was to make these employees healthier, and in the process, improve workforce productivity. The initial results were impressive. The workers underwent significant weight loss in just a week, and showed improved efficiency, energy and confidence.

While the GM Diet Plan for weight loss was deemed a success, and is considered easy to follow, most nutritionists do not recommend that you follow it. Although it results in immediate weight loss, the diet also has several side effects that we shall discuss later in the article.

At HealthifyMe, we believe one should aim to follow a balanced diet that would ensure weight loss while also helping the body absorb the nutrients it requires. If you’re looking for a diet chart to help you lose weight and keep you healthy, we suggest you take a look at the best Indian diet plan for weight loss.

7 Day GM Diet Plan

The GM Diet Plan is focused on ensuring the consumption of complex carbs, along with low-calorie foods. This combined with an increased water intake can result in a significant weight loss in the span of a week. The idea is to limit one’s weekly diet to just fruits, vegetables, brown rice, and chicken. The plan, initially designed for the employees of General Motors, is as shown below.

Day 1
  • All fruits – except bananas
  • Recommended fruits are watermelon and muskmelon
  • 8 to 12 glasses of water
Day 2
  • Large boiled potato
  • Cooked or uncooked vegetables of your choice without oil
  • 8 to 12 glasses of water
Day 3
  • All fruits – except bananas
  • Cooked or uncooked vegetables (except potatoes) of your choice without oil
  • 8 to 12 glasses of water
Day 4
  • 8 to 10 bananas
  • 3 to 4 glasses of milk
  • 8 to 12 glasses of water
Day 5
  • 6 tomatoes
  • One cup of brown rice
  • 12 to 15 glasses of water
Day 6
  • One cup of brown rice
  • Cooked or uncooked vegetables (except potatoes) of your choice without oil
  • 8 to 12 glasses of water
Day 7

  • All fruit juices

GM Diet Plan Indian Version

The Indian version of the GM Diet Plan would not change very much from the original version. While the original GM Diet allows the consumption of meat in the form of beef, this would have to be replaced in India since a sizeable portion of the population does not consume beef.

While the non-vegetarians can still consume protein in the form of chicken on day 5 and 6, the vegetarians can replace the meat with a cup of brown rice.

GM Diet Day 1

sliced fruits

Start the diet by consuming as many fruits as you wish to on the very first day. There are no specific instructions on when one should eat them. However, watermelons and muskmelons are highly recommended since they contain high amounts of fiber. You can also include apples, oranges and papaya in your diet.

Another important part of the diet would be to consume 8 to 12 glasses of water in the day. One must avoid starving at any point of the day. If you’re hungry at any time, feel free to eat some fruits and satisfy your hunger.

These fiber-rich and low-fat foods keep an individual full for longer, thereby reducing an individual’s calorie intake. The high water intake will also serve to flush out the toxins from the body and prepare it for the rest of the diet.

On day one, avoid any kind of vegetables completely. Among fruits, it is ideal to stay away from bananas. Day one should feel a little easier since the monotony of the food would be yet to kick in. Stick to the plan, and feel active and energetic.

8:00 AM1 medium apple 

A few plums or an orange

10:30 AM½ bowl of sliced muskmelon
12:30 PM1 bowl of watermelon
4:00 PM1 large orange or mosambi
6:30 PM1 cup of muskmelon and pomegranate salad
8:30 PM½ cup of watermelon

GM Diet Day 2

The second day of the GM Diet involves eating only vegetables. These veggies can be consumed, or can be cooked in order to make them palatable. Ensure that there is no oil involved in their preparation.

While eating potatoes deep fried, or even a packet of your favourite brand of chips may not be allowed, you can snack on vegetables at any time of the day if you’re hungry. If absolutely required, olive oil or butter can be used sparingly for flavour.

Vegetables contain all the nutrients that you need to sustain the body. You get the necessary carbs from potatoes, protein from peas, and carrots and beans are packed with fiber and all essential vitamins. After a relatively low-carb day one, this will help restore the carbohydrate content in the body. In turn, this will further provide you with enough energy to keep the diet going. Unlike the first day, you must stay away from fruits altogether on day 2.

8:00 AM1 cup of boiled potatoes
10:30 AM½ bowl of cucumber
12:30 PM1 cup of lettuce, spinach, cucumber, and capsicum
4:00 PM½ cup sliced carrots and a glass of lemon juice with a pinch of salt
6:30 PM1 cup boiled broccoli and green peas
8:30 PM1 cucumber

GM Diet Day 3

On the third day of the diet, one must stick to eating a combination of fruits and vegetables. These foods could be the same as that consumed in the first two days. The only foods that must be avoided are potatoes and bananas.

Halfway through the week, your body would have begun to adjust to the new diet. After a day of eating only vegetables, the fruits would be a welcome addition to it. The combination of fruits and vegetables also provides the body with the benefits of high fiber and protein.

You would also need to include 8 to 12 glasses of water in order to flush out all toxins from the body. You can also add the GM Diet Soup to your diet on the third day. In addition to replenishing your body, and giving the body all the nutrients it needs, this variety will also help satisfy your taste buds and break the monotony of the first two days. On this day, one must take care to avoid the consumption of bananas and potatoes.

8:00 AM½ bowl of muskmelon
10:30 AM1 cup of pineapple or pear
12:30 PM1 cup of lettuce, spinach, cucumber, and capsicum
4:00 PM½ cup sliced carrots and a glass of lemon juice with a pinch of salt
6:30 PM1 cup of boiled broccoli and green peas
8:30 PM1 cucumber

GM Diet Day 4

bananas for gm diet day 4

The bananas that were avoided over the first three days, can finally be consumed on the fourth day. One must consume 8 bananas over the course of the day. The consumption can be split across the day’s meal and snack times. In addition to that, one should also consume a big glass of milk each, at breakfast, lunch and dinner. In case this becomes monotonous, a bowl of soup can be included in the diet.

Bananas are rich in pectin, and hence, they help in digestion. They also provide one’s body with the instant energy they need. They are also high in potassium, apart from being low in salt. Additionally, the milk one consumes on this day is also a great source of potassium and calcium. Thanks to being fortified with Vitamin D, the milk further helps strengthen bones.

On Day 4, one must completely avoid snacking on fruits other than bananas. Potatoes and sweet potatoes must be ignored as well. You could also substitute bananas and milk with fig and soy milk.

8:00 AM2 bananas
10:30 AM1 banana
12:30 PMMilkshake (2 bananas + 1 glass of milk + a dash of cocoa powder)
4:00 PM2 bananas
6:30 PM1 banana

1 glass of milk

8:30 PM1 glass of milk

GM Diet Day 5

On day 5, vegetarians can opt to eat a bowl of brown rice, while non-vegetarians can consume a lean protein source like fish or chicken breast. In addition to that, one must also eat 6 large tomatoes.

While vegetarians can eat a bowl of brown rice for lunch, care must be taken to ensure that minimal oil is used for cooking. Combat the high amounts of uric acid that your body will be producing by drinking upto 15 glasses of water everyday. Non-vegetarians can eat about 500 g of baked or lightly fried skinless chicken, along with the 6 tomatoes.

Brown rice is rich in fiber, and helps with digestion. At the same time, chicken and fish are excellent sources of lean protein. Additionally, fish also has omega-3 fatty acids. The high fiber in tomatoes mean they aid digestion too.

It is important to avoid potatoes and sweet potatoes among vegetables, and bananas among fruits that were recommended earlier in the week. One can also have a bowl of GM Diet Soup as part of the mid-morning or evening snack.

9:00 AM3 tomatoes
12:30 PM½ cup of brown rice 

Sautéed assorted veggies

4:00 PM2 tomatoes
6:30 PM1 bowl of brown rice 

1 tomato 

½ cup of sautéed veggies 

GM Diet Day 6

Day 6 of the GM Diet requires the individual to have cooked or uncooked vegetables. Vegetarians can opt for a cup of brown rice, while non-vegetarians can include a lean protein source like fish or chicken breast in their diet.

Another relatively high food intake day, the sixth day also follows a pattern similar to the previous day with the addition of cooked or uncooked vegetables. One must make sure that the vegetables are boiled and not fried. The salads should not have any heavy dressing either.

Non-vegetarians can consume up to 500 g of skinless chicken along with vegetables apart from tomatoes and potatoes. In addition to the previous day’s foods, the mix of vegetables on day 6 also provides the fiber the body requires.

Ideally, one must avoid all fruits along with potatoes and sweet potatoes. On the sixth day, the weight loss with now be visible.

9:00 AM1 glass carrot juice
12:30 PM½ cup of brown rice + ½ cup of veggies
4:00 PM1 cup of cucumber slices
6:30 PM½ bowl of brown rice 

½ cup of veggiesChicken/cottage cheese

GM Diet Day 7

On the last day of the 7-day plan, one would need a cup of brown rice, an assortment of vegetables and fruit juice. One can eat a cup of brown rice along with a bowl of boiled vegetables for lunch. Drink sugarless fruit juice after every meal or snack to complement the nutrient-rich vegetables.

The rice and vegetables will provide the body with some much-needed energy to keep the body going right through the day. The fruit juices will help flush out the toxins from the system.

As with the previous 6 days, one must avoid certain foods on the seventh day as well. It is advisable to stay clear of vegetables like potatoes and sweet potatoes whereas fruits like banana, cherry, mango and pear are to be avoided as well.

9:00 AM1 glass of orange/apple juice
12:30 PM½ cup of brown rice 

½ cup of sautéed veggies

4:00 PM1 cup of watermelon/few assorted berries
6:30 PM1 bowl of GM Soup

GM Diet Soup Recipe

The GM diet soup is an important part of the diet. It can be consumed in relatively higher quantities on any day, in order to make sure that one doesn’t go hungry.

GM Diet Side Effects

The GM Diet is popular the world over. However, they have several side effects that need to be considered before one chooses to follow the diet.

    • Although the diet may help you lose weight quickly, it is high in fiber but low in protein, carbs and fats. Due to this, your body may not receive the nutrients it requires.
    • The GM Diet can lead to metabolic slowdown in your body. While your weight loss may not be affected initially, this would make it difficult to maintain your body weight.
    • The body would use all the fluids in the diet for metabolism. The diet could, therefore, lead to dehydration.
    • The other possible side effects of the GM Diet also includes weakness, headaches, and hunger pangs.

Expert Review

GM diet is a crash diet that goes against the principles of a balanced diet. Though the weight loss or the results are pretty quick and evident, the long term effects are more damaging. Since you undergo a drastic change in your regular eating routine, the body sheds weight and when you resume your normal diet, one gains as much or more weight than they lost.

I personally believe that any diet which requires you to stop eating your day-to-day regular staple food is not sustainable. Weight management requires consistently good eating habits and a balanced diet with all nutrients. Avoid following an unrealistic diet that requires extra effort to change your lifestyle completely, and put the same effort into balancing your daily meals. This will help maintain a good lifestyle change, and ensure sustainable weight management.


By focusing on the consumption of complex carbs and low-calorie foods, the GM Diet Plan almost guarantees weight loss. However, following the GM Diet could lead to an individual not receiving the nutrients they require. In addition to that, it could also make it difficult to maintain one’s body weight after the diet has helped one lose weight.
