Cabbage Soup Diet: 7-Day Risks, Benefits, And Alternatives

The cabbage soup diet is a fad diet popularized in the 1980s that promises rapid weight loss of up to 10-15 pounds in just one week by consuming unlimited amounts of low-calorie cabbage soup alongside limited other foods. While it may lead to short-term scale victories, primarily from water weight loss rather than fat reduction, experts widely agree it is not healthy or sustainable long-term due to extreme calorie restriction and nutritional imbalances.

What Is the Cabbage Soup Diet?

The cabbage soup diet, also known as the sacred heart diet or military cabbage soup diet in some variations, centers on a homemade soup made from cabbage, tomatoes, onions, peppers, carrots, celery, and herbs, simmered in a low-calorie broth. This soup is eaten in unlimited quantities throughout the day for seven days, supplemented by specific fruits, vegetables, proteins, and grains on designated days. Proponents claim the soup’s ingredients, particularly cabbage, act as a ‘fat-burner,’ but no scientific evidence supports this; weight loss stems from a severe calorie deficit of under 1,000 calories daily on most days.

The diet’s origins are anonymous, with countless variations circulating online. A typical recipe yields a large batch (around 400 calories per full recipe serving but high in sodium at 2,100mg), including nutritional breakdowns like 92g total carbs, 35g fiber, and only 19g protein. Cabbage itself is nutritious—low in calories, high in vitamins C and K, and fiber—but the diet’s restrictive nature overrides these benefits.

How Does the Cabbage Soup Diet Work?

The diet follows a strict 7-day meal plan where cabbage soup is the staple, with additional allowed foods varying daily to provide minimal variety and prevent total starvation. Caloric intake hovers between 800-1,200 calories daily, far below the 2,000 needed for most adults, forcing the body to burn glycogen stores. This process releases bound water, accounting for most ‘losses’—not fat.

Here’s the standard 7-day plan:

• Day 1: Unlimited cabbage soup and fruits (except bananas). Focus on melons and water-rich options for hydration.
• Day 2: Unlimited cabbage soup and non-starchy vegetables (no potatoes). Raw or cooked greens encouraged.
• Day 3: Unlimited cabbage soup, fruits, and vegetables (no potatoes or bananas). Combine Days 1 and 2.
• Day 4: Unlimited cabbage soup, up to 8 bananas, and skim milk. Bananas provide potassium to offset sodium.
• Day 5: Unlimited cabbage soup, 6 tomatoes, and 10-20 oz (565g) lean beef, chicken, or fish.
• Day 6: Unlimited cabbage soup and beef/lean protein with unlimited vegetables (no potatoes).
• Day 7: Unlimited cabbage soup, brown rice, sugar-free fruit juice, and vegetables (no potatoes).

Beverages are limited to water, black coffee, tea, or cranberry juice. No exercise is recommended due to low energy availability.

Does the Cabbage Soup Diet Work for Weight Loss?

Short answer: Yes, temporarily. Followers may lose 10 pounds or more in a week due to the drastic calorie cut, but this is mostly water weight from glycogen depletion and not fat loss—equivalent to 40-60 sticks of butter in fat terms, which is impossible in seven days. Studies and experts confirm no evidence for its effectiveness beyond short-term, with nearly all weight regained upon resuming normal eating.

Anecdotal reports abound, but health authorities like those cited by Medical News Today state there’s no scientific backing for healthy, sustainable weight loss. The structured plan can kickstart habits for some, but cravings and fatigue often lead to yo-yo dieting.

Potential Health Benefits of the Cabbage Soup Diet

Despite criticisms, a few upsides exist:

• Low-Calorie, Veggie-Heavy: Emphasizes fruits and vegetables, providing fiber, vitamins, and antioxidants. Cabbage offers vitamin C (over 50% DV per cup) and K.
• Quick Motivation: Rapid initial loss can motivate long-term changes if transitioned properly.
• Cost-Effective: Uses inexpensive ingredients like cabbage ($0.50/lb) and pantry staples.
• Structure: Detailed plan aids those struggling with meal decisions, promoting heart-healthy foods like lean meats and whole grains on later days.

However, these benefits are overshadowed by risks, and the same nutrients are better obtained through balanced diets.

Cabbage Soup Diet Risks and Downsides

The diet’s extremes pose significant health threats:

• Nutrient Deficiencies: Very low in protein (risking muscle loss), fats, carbs, calcium, and B vitamins. Days 1-3 provide <1,000 calories, inadequate without supplements.
• Side Effects: Fatigue, dizziness, lightheadedness, cravings, constipation from low fiber diversity, and high sodium (2,100mg+ per batch) causing bloating.
• Water Weight Rebound: Glycogen restoration post-diet leads to quick regain.
• Danger for Specific Groups: Diabetics risk blood sugar crashes from low carbs; those on medications face interactions.
• No Exercise Support: Insufficient calories hinder activity, stalling metabolism.

University of Florida nutritionist Elaine Turner notes it’s ‘physically impossible’ to lose promised fat, calling it no ‘lucky charm’ for lasting results.

Is the Cabbage Soup Diet Safe?

No, it’s not recommended by health authorities. The extreme restriction mimics crash dieting, linked to gallstones, electrolyte imbalances, and metabolic slowdown. WebMD and Healthline highlight lacks in essential macros, advising against it without medical supervision—rarely warranted. For sustainable loss, aim for 1-2 pounds weekly via 500-calorie deficits.

Healthier Alternatives to the Cabbage Soup Diet

Opt for evidence-based plans:

Incorporate cabbage soup occasionally as a low-cal starter, adding protein like chicken or tofu for balance. Focus on whole foods, portion control, and exercise for lasting results.
