Cabbage soup for weight loss is simple to make, low in calories, and filling enough to replace heavier meals. A typical bowl lands well under 100 calories, making it hard to exceed 1,000 calories in a day even if you eat it multiple times. Here’s how to make it, how to keep it interesting, and what to realistically expect.
The Basic Recipe
This version uses widely available ingredients and takes about 30 minutes of active work. It makes a large batch, roughly 8 servings, so you can refrigerate or freeze portions for the week.
Ingredients:
- 2 tablespoons olive oil
- 1 cup diced celery
- 1 cup diced onion (white or yellow)
- 1 green bell pepper, diced
- 1 cup diced carrots
- 2 to 3 cloves garlic, minced
- 4 cups chicken or vegetable broth (low-sodium if possible)
- 1 can (14 oz) diced tomatoes (look for one seasoned with basil, oregano, and garlic)
- Half a head of cabbage, chopped
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- Half a teaspoon red pepper flakes
- Black pepper to taste
- Half a teaspoon salt (optional)
Instructions:
Heat the olive oil in a large pot over medium heat. Add the celery, onion, bell pepper, and carrots. Cook for about 5 minutes, stirring occasionally, until the onion turns translucent. Add the garlic and stir for another 30 seconds.
Pour in the broth and diced tomatoes, then add the chopped cabbage. Stir in the oregano, basil, red pepper flakes, and black pepper. Bring the pot to a boil, then reduce the heat and let it simmer for 15 to 20 minutes, until the cabbage is tender and the carrots are soft. Taste and adjust salt if needed.
Why This Soup Works for Weight Loss
The math is straightforward: cabbage soup is extremely low in calories but high in fiber and water, both of which help you feel full. Vegetables like cabbage, carrots, and celery are bulky foods that take up space in your stomach without delivering many calories. When you swap a 500-calorie dinner for a bowl of this soup, you create a significant calorie gap without going hungry.
The soup also requires almost no added fat beyond the olive oil used for sautéing. Using low-sodium broth keeps the sodium in check, which matters because excess sodium causes water retention and masks actual fat loss on the scale.
The 7-Day Cabbage Soup Diet
You may have heard of the “cabbage soup diet,” a strict 7-day plan where you eat the soup at every meal alongside a limited rotation of other foods: fruit on some days, vegetables on others, with small amounts of meat or rice toward the end of the week. Proponents claim you can lose up to 10 pounds in a week.
Most of that loss is water weight, not fat. The plan is so low in calories that reaching even 1,000 calories per day is difficult. It’s also deficient in protein on most days and lacks key vitamins and minerals. A nutrition expert at the University of Florida put it bluntly: the diet provides inadequate nutrition, and the plan’s own structure essentially acknowledges that by cycling in different foods each day to patch the gaps.
You don’t need to follow this rigid protocol to benefit from the soup. A more practical approach is using cabbage soup as one low-calorie meal per day while eating balanced meals the rest of the time. You’ll lose weight more slowly, but you’ll actually lose fat rather than water you’ll regain within days.
Making It More Filling and Sustainable
The biggest complaint about plain cabbage soup is that it doesn’t keep you full for long. That’s because it’s almost entirely vegetables with very little protein or fat. A few additions fix this without dramatically raising the calorie count.
For protein, white beans, red lentils, or chickpeas are the easiest options. A half cup of cooked lentils adds around 9 grams of protein and makes the soup feel like a real meal rather than a side dish. Shredded chicken breast works too, especially if you cook it separately and add it per bowl so leftovers don’t get soggy. Some people stir in a spoonful of plain yogurt for creaminess and a small protein bump.
These modifications matter for weight loss specifically. Protein helps preserve muscle mass when you’re eating fewer calories overall. Without it, your body breaks down muscle for energy, which lowers your metabolism and makes regaining weight easier once you stop dieting.
Seasoning Tips to Prevent Flavor Fatigue
If you’re eating this soup several times a week, the baseline herbs and red pepper flakes will get old fast. Fortunately, spices and herbs add almost zero calories.
A bay leaf or two simmered with the broth adds depth. Cumin and smoked paprika push the soup toward a Tex-Mex profile, especially if you add a squeeze of lime before serving. Fresh ginger and a splash of soy sauce (low-sodium) give it an Asian-inspired direction. Italian seasoning with a parmesan rind dropped into the pot during simmering creates a richer, savory base. Swapping the diced tomatoes for fire-roasted tomatoes is another easy upgrade.
Rotating between two or three flavor profiles each week keeps things interesting enough that you won’t dread opening the container.
Dealing With Bloating and Gas
Cabbage is a cruciferous vegetable, and eating large amounts of it can cause gas, bloating, and sometimes diarrhea. This is especially common if your diet hasn’t included much fiber recently. The fiber and certain sugars in cabbage are fermented by gut bacteria, which produces gas as a byproduct.
The best strategy is to start with smaller portions and increase gradually over a few days. Cooking cabbage thoroughly (rather than leaving it crunchy) also breaks down some of the compounds that cause digestive trouble. If you find that cabbage consistently bothers your stomach even in moderate amounts, you can reduce the cabbage by half and bulk up the soup with zucchini, green beans, or spinach, which are gentler on digestion but similarly low in calories.
Storage and Batch Cooking
This soup refrigerates well for 4 to 5 days in airtight containers. It actually improves overnight as the flavors meld. For freezing, portion it into individual servings and freeze for up to 3 months. Leave protein additions out of any portions you plan to freeze, since beans and especially chicken can change texture after thawing.
Making a double batch on Sunday and portioning it out gives you a grab-and-go lunch for the work week. Reheat on the stove or in the microwave, adding a splash of broth if the soup has thickened in the fridge.
Realistic Weight Loss Expectations
If you use cabbage soup to replace one meal per day and keep your other meals balanced, you can expect to cut 300 to 500 calories daily depending on what you were eating before. That translates to roughly 0.5 to 1 pound of fat loss per week, which is the range most likely to stay off long-term.
If you follow the strict 7-day plan, you may see the scale drop several pounds in a week, but most of that will return once you resume normal eating. The extremely low calorie intake also tends to leave people fatigued, irritable, and prone to overeating the following week. For most people, the moderate approach delivers better results over any meaningful timeframe.
