The GM diet, short for General Motors diet, is a popular weight-loss plan that promises quick results. This diet is structured over a week and is said to help you lose up to 15 pounds (6.8 kg) in that time frame. However, before deciding to follow this diet, it’s essential to understand its structure, claims, and potential pros and cons.
What is the GM Diet?
The GM diet was allegedly developed by General Motors for its employees in the 1980s, though there’s no substantial evidence to support this origin story. The diet plan is divided into seven days, each with specific food types allowed:
- Day 1: Fruits, especially melons. Avoid bananas.
- Day 2: Vegetables only, with a focus on raw or cooked greens.
- Day 3: A combination of fruits and vegetables. Bananas and potatoes are excluded.
- Day 4: Bananas and milk only. Up to six bananas and several glasses of milk.
- Day 5: Protein, specifically beef or chicken, with tomatoes.
- Day 6: Beef and vegetables.
- Day 7: Brown rice, fruit juices, and vegetables.
Claims and Expectations
The GM diet claims to enhance weight loss by creating a caloric deficit while consuming specific foods purportedly aiding fat burning. Proponents argue it encourages detoxification and boosts energy.

Pros of the GM Diet
- Quick Results: Followers often report significant weight loss within a week.
- Simplicity: The diet has clear guidelines about what to eat each day.
- Focus on Fruits and Vegetables: The diet encourages consuming large amounts of fresh fruits and vegetables, which are nutrient-dense and low in calories.
Cons of the GM Diet
- Nutritional Imbalance: The restrictive nature can lead to nutrient deficiencies, especially in protein, fats, and certain vitamins and minerals.
- Short-term Solution: Like most crash diets, it’s not sustainable long-term. Rapid weight loss may be followed by equally rapid weight gain once regular eating resumes.
- Potential Side Effects: Followers may experience fatigue, weakness, or a decline in exercise performance due to low caloric intake.
- Lack of Scientific Support: There’s limited scientific evidence to back the health claims associated with this diet.

Should You Try the GM Diet?
Before deciding, consider your personal health goals and lifestyle. Here are some points to ponder:
- Consult a Healthcare Professional: Especially important for individuals with underlying health conditions.
- Long-term Health Goals: Focus on building sustainable eating habits rather than seeking quick fixes.
- Balanced Nutrition: Ensure that any diet plan provides adequate nutrition to support both physical and mental health.
