GM Diet – 7 Day Diet Chart, Foods List, Benefits & Risks

GM diet or General Motors diet is a popular weight-loss fad diet. It claims to aid 15-17 lbs weight loss in just 7 days! However, losing weight so quickly can be harmful, and there are no scientific studies that prove the GM diet plan is safe, reliable, or sustainable. In this post, we disclose everything you need to know about the GM diet and whether it is safe for quick weight loss or not. Scroll down!

What Is The GM Diet?

The GM diet is a 7-Day diet plan for quick weight loss.

It was created in 1985 by General Motors to help its employees lose weight.  The employees consumed low-calorie food groups on different days. By the end of the first week, the employees lost up to 17 lbs (7.7 kgs).

The employees consumed low-calorie food groups on different days. This is believed to have triggered the weight loss.

This made the GM diet a popular short-cut to losing weight. Does it really work? Find out next.

Does GM Diet Really Work?

Going on a very low-calorie diet might work for weight loss. But these diets are not safe and are tough to follow. The proponents of the GM diet believe that it works based on the following factors:

  • It Is Low In Calories: Weight loss is calculated by the number of calories you consume and the number of calories you burn. When you consume fewer calories, your body shifts to a negative energy balance. This makes you lose weight.
  • It Boosts Metabolism: The foods included in this diet plan are believed to boost your metabolism and keep your body in the fat-burning mode. However, there is no study that backs this claim.
  • It Includes Negative Calorie Foods: Negative calorie foods burn calories during their digestion and processing. This means you lose weight by burning calories even when you eat. It sounds good, but dietitians and nutritionists do not believe in the term “negative calorie foods“.
  • It Is A Good Detox: Consuming healthy food and staying hydrated may help flush out toxins.
  • May Improve Digestion: The fruits and vegetables in the GM diet contain dietary fiber, which helps improve bowel movement and digestion. However, it is not established if the GM diet follows the recommended 25 g dietary fiber/day based on a 2000-calorie diet (1) or not.

The GM diet was created to aid quick weight loss in employees of General Motors. Here’s what they were allowed to eat for a week:

GM Diet Benefits

The benefits of the GM diet are not backed by evidence, but certain scientific facts pertaining to the foods included in this diet hold true:

  • Detoxification – Fruits and vegetables are loaded with antioxidants that help flush out toxins (2).
  • Improves Health – Veggies and fruits boost immunity and improve cell functions (3), (4).
  • Prevents Weight Gain – Cutting back on sugar and sugary foods help prevent weight gain (5), (6).

However, there are possible side effects or risks associated with the GM diet.

GM Diet Risks And Side Effects

  • There Is No Scientific Backing – The GM diet is not backed by any scientific study.
  • No Long-Term Weight Loss – The GM diet is a fad diet and is not recommended for long-term weight loss goals.
  • Lacks Nutrients – Limited access to foods makes the GM diet lacking in nutrients like vitamin B12, calcium, and iron.
  • Muscle Loss – Low-calorie diets, more often than not, cause muscle loss. This can ultimately cause slow metabolism, which can make it difficult to maintain weight loss in the future (7), (8). The muscle tissues are deprived of an adequate amount of proteins, which can also lead to physical weakness.
  • Mood Swings – This restrictive diet can cause mood swings and irritability.
  • Tiredness And Fatigue – A sudden dip in calorie intake might make you feel tired and weak.

Now that you know both sides of the coin, should you really try the GM Diet to lose weight?

Should You Go On The GM Diet To Lose Weight?

Losing weight is tough. It takes time, patience, and determination. Quick weight loss or a shortcut like the GM diet may fix a temporary problem, but it is not suitable for long-term weight loss. You must eat healthy, exercise, get 7-8 hours of sleep, and meditate to keep the excess flab away in the long run. Going on a diet that is not backed by science, doctors, nutritionists, and dietitians is not worth risking your health and well-being.

Conclusion

The GM diet was created for the employees of General Motors. It lacks scientific research and evidence. Three decades later, the GM diet is still not the ultimate diet for quick weight loss. In fact, dietitians and nutritionists advise against opting for shortcuts to weight loss. Moreover, going on a low-calorie diet without being supervised by a licensed professional is a strict no-no. If you want to lose weight, talk to a doctor or dietitian and get a customized diet chart. You will not only lose weight but also improve your overall health.
