Understanding the Cabbage Soup Diet

The cabbage soup diet is a short-term, rapid weight loss plan that has been circulating for decades. Often classified as a fad diet, it requires participants to consume homemade cabbage soup as the primary food source for seven consecutive days.

The premise is simple: eat as much cabbage soup as you want throughout the day, supplemented with specific low-calorie foods that vary depending on which day of the week you’re on. Proponents claim this approach can help you shed up to 10 pounds in a single week, making it an attractive option for people looking for quick results before a special event or as a jump-start to a longer-term weight loss journey.

However, it’s important to understand that this diet has never been scientifically studied in controlled research settings, so many claims about its effectiveness are based on anecdotal evidence rather than clinical data.

How Does the Cabbage Soup Diet Work for Weight Loss?

The cabbage soup diet works primarily through severe calorie restriction. The foods allowed on this diet are extremely low in calories, making it difficult to consume more than 800-1,000 calories per day—well below the minimum recommended intake for most adults.

The Science Behind Rapid Weight Loss

When you drastically reduce your calorie intake, your body initially responds by burning through its glycogen stores—your body’s quick-access energy reserves. Glycogen is stored with water molecules, so when these stores are depleted, you lose significant water weight.

Research shows that during the first week of a very low-calorie diet, only about 34% of weight lost comes from actual fat. The remaining two-thirds consists of water weight and, unfortunately, some muscle mass. This explains why the weight loss feels so dramatic initially but is rarely sustainable long-term.

Metabolic Adaptation

One critical factor to understand is metabolic adaptation. When you severely restrict calories, your body responds by lowering your metabolic rate to conserve energy. Studies indicate this slowdown can occur as early as three days into a very low-calorie diet.

This metabolic adjustment is your body’s survival mechanism, but it makes continued weight loss more difficult and explains why most people quickly regain weight once they return to normal eating patterns.

Is Cabbage Good for Weight Loss?

Beyond the specific diet plan, many people wonder whether cabbage itself has special weight loss properties. The answer is nuanced.

Cabbage is indeed an excellent food for weight loss support due to several factors:

Low in calories: One cup of raw cabbage contains only about 22 calories, allowing you to eat large volumes without consuming many calories.
High in fiber: Cabbage provides substantial dietary fiber, which promotes feelings of fullness and supports digestive health.
Rich in nutrients: This cruciferous vegetable contains vitamins C and K, folate, and various antioxidants that support overall health.
High water content: Like most vegetables, cabbage has a high water content, which adds volume to meals without adding calories.

However, eating cabbage alone—or primarily cabbage soup—is not a magic solution for weight loss. Sustainable weight management requires a balanced approach that includes various nutrient-dense foods, adequate protein, healthy fats, and appropriate calorie intake for your individual needs.

The 7-Day Cabbage Soup Diet Plan

The standard cabbage soup diet follows a specific structure for each day of the week. Here’s what the typical plan looks like:

Basic Cabbage Soup Recipe

Before starting the diet, you’ll need to prepare a large batch of cabbage soup. While variations exist, most recipes include:

1 head of cabbage, chopped
2 large onions, diced
2 green bell peppers, chopped
2 cans of tomatoes (or fresh equivalent)
1 bunch of celery, chopped
3 large carrots, sliced
1 package of mushrooms, sliced
6-8 cups of water or low-sodium vegetable broth
Seasonings: garlic, pepper, herbs, hot sauce (to taste)

Preparation is straightforward: chop all vegetables, sauté the onions briefly in a small amount of oil, add remaining vegetables and liquid, bring to a boil, then simmer for 30-45 minutes until vegetables are tender.

Daily Meal Plan Structure

Day 1: Cabbage soup plus unlimited fruit (except bananas). Focus on fruits with high water content like watermelon, strawberries, and cantaloupe.

Day 2: Cabbage soup and vegetables only. Emphasize leafy greens and other non-starchy vegetables. Avoid peas, corn, and beans. You may have one baked potato with a small amount of butter.

Day 3: Cabbage soup, fruits, and vegetables. Eat as much as you want from both categories, but skip the baked potato and still avoid bananas.

Day 4: Cabbage soup, up to eight bananas, and unlimited skim milk. This is the first day you’re allowed bananas, which provide potassium that may be lacking in previous days.

Day 5: Cabbage soup plus 10-20 ounces of beef, chicken, or fish. You may also eat up to six fresh tomatoes. Drink at least six to eight glasses of water to help flush uric acid from your body.

Day 6: Cabbage soup, beef (or fish if you prefer), and unlimited vegetables. Focus on leafy greens and skip the baked potato.

Day 7: Cabbage soup, brown rice, vegetables, and unlimited unsweetened fruit juice.

Throughout all seven days, you should eat the cabbage soup at least once daily, though most people eat it two to three times per day. You can drink water, unsweetened tea, black coffee, and other zero-calorie beverages.

Potential Benefits of the Cabbage Soup Diet

While this diet has significant drawbacks (which we’ll cover shortly), it does offer some potential benefits for certain situations:

Quick Initial Results

The most obvious benefit is rapid initial weight loss. If you have a special event coming up and want to lose a few pounds quickly, this diet can deliver visible results within a week. However, remember that most of this weight loss is water and not fat.

Simple and Straightforward

Unlike many diet plans that require complex meal planning, calorie counting, or expensive specialty foods, the cabbage soup diet is remarkably simple. The rules are clear, the recipes are basic, and the ingredients are inexpensive and readily available at any grocery store.

Increased Vegetable Intake

For people who typically don’t eat many vegetables, this diet dramatically increases vegetable consumption. The soup itself contains multiple servings of nutrient-rich vegetables, and most days include additional vegetables as well.

May Improve Short-Term Health Markers

Some research on very low-calorie diets suggests they may temporarily improve certain health markers. A 2021 study found that short-term, very low-calorie diets could temporarily decrease insulin resistance in people with obesity, even when the diet period is too brief to produce significant changes in body fat composition.

Cost-Effective

Compared to many commercial diet programs or meal replacement products, the cabbage soup diet is extremely affordable. The vegetables needed for the soup are among the least expensive produce items, making this accessible even for people on tight budgets.

No Special Equipment Needed

You don’t need any special equipment, supplements, or products. Just a large pot for making soup and basic kitchen tools for chopping vegetables.

Significant Drawbacks and Concerns

Despite some potential benefits, the cabbage soup diet has numerous drawbacks that outweigh its advantages for most people:

Unsustainable Weight Loss

The fundamental problem with this diet is that results are temporary. Because most weight lost is water and muscle rather than fat, you’ll likely regain the weight quickly once you resume normal eating. The diet does nothing to teach healthy eating habits or create sustainable lifestyle changes.

Severe Nutritional Deficiencies

The cabbage soup diet is nutritionally inadequate in multiple ways:

Insufficient protein: Most days provide little to no protein, which can lead to muscle loss and decreased metabolic rate.
Low in healthy fats: The diet contains almost no fat, yet healthy fats are essential for hormone production, nutrient absorption, and brain function.
Vitamin and mineral deficiencies: While vegetables provide some micronutrients, the limited food variety means you’re missing many essential vitamins and minerals.
Low in complex carbohydrates: Your body needs adequate carbohydrates for energy, especially if you’re physically active.

Difficult to Follow

Many people find the cabbage soup diet extremely difficult to stick with for a full week. The monotony of eating the same soup repeatedly, combined with hunger from low calorie intake, makes compliance challenging. Social situations become problematic when your food choices are so restricted.

Unpleasant Side Effects

The high fiber content and specific vegetable combinations in the soup frequently cause digestive discomfort, including:

Excessive gas and bloating
Abdominal cramping
Frequent bowel movements
General gastrointestinal distress

Additionally, very low calorie intake can cause dizziness, weakness, lightheadedness, difficulty concentrating, and irritability.

Muscle Loss

Without adequate protein and calories, your body will break down muscle tissue for energy. Muscle loss is problematic because muscle tissue burns more calories at rest than fat tissue, so losing muscle actually decreases your metabolic rate, making weight management more difficult long-term.

Blood Sugar Concerns

The extremely low calorie and carbohydrate content can cause concerning blood sugar fluctuations. This is particularly dangerous for people with diabetes or prediabetes. If you have any blood sugar regulation issues, you should avoid this diet entirely or only attempt it under close medical supervision.

Potential Gallbladder Problems

Rapid weight loss from any cause increases the risk of gallstone formation. When you eat very little fat, your gallbladder doesn’t empty regularly, which can lead to bile crystallization and stone formation. Some people following the cabbage soup diet have reported gallstones and gallbladder blockages, though these cases are anecdotal.

May Trigger Disordered Eating

Restrictive fad diets can trigger or worsen disordered eating patterns, particularly in people with a history of eating disorders. The strict rules, rapid weight loss, and inevitable rebound weight gain can create an unhealthy cycle of restriction and overeating.

Who Should Avoid the Cabbage Soup Diet?

Certain people should not attempt this diet under any circumstances:

Pregnant or nursing women: The nutritional needs during pregnancy and breastfeeding are much higher than what this diet provides.
People with diabetes: The dramatic blood sugar fluctuations could be dangerous.
Individuals with eating disorder history: Restrictive diets can trigger relapse or worsen symptoms.
People with kidney disease: The high vegetable intake affects potassium levels, which can be problematic for kidney function.
Those with digestive disorders: The high fiber content may worsen symptoms of IBS, Crohn’s disease, or other digestive conditions.
Anyone with chronic health conditions: Talk to your healthcare provider before attempting any extreme diet.
Active individuals or athletes: The low calorie and protein content won’t support exercise performance or recovery.
Children and teenagers: Growing bodies need adequate nutrition that this diet cannot provide.

Even if you don’t fall into these categories, it’s wise to consult with a healthcare provider before starting any very low-calorie diet plan.

Healthier Alternatives for Sustainable Weight Loss

Rather than following a restrictive fad diet like the cabbage soup diet, consider these evidence-based approaches to sustainable weight loss:

Mediterranean-Style Eating

The Mediterranean diet emphasizes whole foods including fruits, vegetables, whole grains, legumes, nuts, seeds, fish, and olive oil. Research consistently shows this eating pattern supports weight management while reducing disease risk and improving overall health.

Balanced Calorie Reduction

Instead of extreme restriction, aim for a moderate calorie deficit of 300-500 calories per day below your maintenance needs. This allows for steady, sustainable weight loss of about 0.5-1 pound per week while preserving muscle mass and metabolic rate.

Time-Restricted Eating

Intermittent fasting approaches, such as eating within an 8-10 hour window each day, can help reduce overall calorie intake without strict food restrictions. This may be easier to maintain long-term than severely restrictive diets.

Mindful Eating Practices

Focusing on eating slowly, recognizing hunger and fullness cues, and minimizing distractions during meals can help you naturally regulate food intake without rigid rules.

Increase Whole Food Intake

Emphasizing minimally processed foods—including plenty of vegetables like cabbage—naturally reduces calorie density while increasing nutrient intake. You can enjoy cabbage and other vegetables as part of a varied, balanced diet without restricting yourself to soup alone.

Include Adequate Protein

Consuming adequate protein (about 0.7-1 gram per pound of body weight) helps preserve muscle mass during weight loss, keeps you feeling full, and supports a healthy metabolism.

Regular Physical Activity

Combining dietary changes with regular exercise—both cardiovascular activity and strength training—improves weight loss outcomes and helps maintain results long-term.

Making Cabbage Soup Part of a Healthy Diet

While the cabbage soup diet itself isn’t recommended, cabbage soup can be a nutritious component of a balanced eating plan:

Enhance the Nutrition

Improve the basic cabbage soup recipe by adding:

Lean protein sources like shredded chicken, turkey, or white beans
Whole grains such as barley, brown rice, or quinoa
Healthy fats from a drizzle of olive oil or some avocado on top
Additional vegetables for more variety in nutrients and flavors
Herbs and spices for flavor without added calories

Use as One Meal Component

Rather than eating only cabbage soup, enjoy it as:

A starter course before a balanced meal
A side dish alongside lean protein and whole grains
One meal in a day that includes other nutritious foods
Part of a meal prep routine for convenient, healthy lunches

Vegetable Soup Benefits

Research shows that starting meals with a low-calorie soup can help reduce overall calorie intake by promoting feelings of fullness. Using vegetable-based soups strategically can support weight management without the extreme restriction of the cabbage soup diet.

The Bottom Line: Is the Cabbage Soup Diet Worth Trying?

For most people, the cabbage soup diet is not a worthwhile weight loss strategy. While it may deliver rapid initial results, these come primarily from water loss and are quickly regained. The diet’s severe nutritional deficiencies, uncomfortable side effects, and inability to teach sustainable eating habits make it a poor choice for long-term health.

If you’re considering this diet because you need to lose weight quickly for a specific event, understand that the results will be temporary and mostly cosmetic (from water loss rather than fat loss). You’ll likely feel uncomfortable during the week and regain the weight shortly after stopping.

For meaningful, sustainable weight loss that improves your health, focus on creating a balanced eating pattern you can maintain long-term. This should include plenty of vegetables (including cabbage!), adequate protein, healthy fats, whole grains, and appropriate portions for your individual needs.

If you’re struggling with weight management, consider working with a registered dietitian or healthcare provider who can help you develop a personalized plan based on your health status, preferences, and lifestyle. They can provide evidence-based guidance that supports your goals without the risks associated with extreme fad diets.

Remember: sustainable weight loss is a journey, not a race. The most effective approach is one that you can maintain for life, not just for seven days.

Frequently Asked Questions

Can I follow the cabbage soup diet for longer than one week?

No, the cabbage soup diet should not be followed for more than seven days due to its severe nutritional deficiencies. Extended use could lead to serious health problems including malnutrition, muscle wasting, and metabolic disturbances. If you want to repeat the diet, wait at least two weeks between cycles, though this approach still isn’t recommended for healthy weight management.

Will I gain all the weight back after stopping the diet?

Most likely, yes. The majority of weight lost on the cabbage soup diet is water weight and some muscle mass, not body fat. When you resume normal eating, your body will replenish glycogen stores and the associated water weight, causing the scale to return to near your starting weight within days.

Can I exercise while on the cabbage soup diet?

Intense exercise is not recommended during the cabbage soup diet because you won’t be consuming enough calories or protein to fuel workouts or support recovery. Light activities like walking may be tolerable, but many people experience fatigue and weakness that limits physical activity.

Are there any medications I should avoid while on this diet?

The cabbage soup diet can interact with various medications, particularly those for diabetes, blood pressure, and other chronic conditions. Always consult your healthcare provider before starting any extreme diet, especially if you take prescription medications. They can advise you on potential interactions and whether the diet is safe given your medical history.

Is cabbage soup healthy to eat regularly outside of the diet?

Yes! Cabbage soup can be a healthy, nutritious food when it’s part of a balanced diet rather than the only thing you eat. Enhance the basic recipe with protein, healthy fats, and whole grains to make it more nutritionally complete. Regular consumption of vegetable-rich soups is associated with increased vegetable intake and can support overall health.
