What Registered Dietitians Say About the Cabbage Soup Diet Today
A look at how registered dietitians view the long-running cabbage soup diet and the concerns they raise about its nutritional limits.
The cabbage soup diet has resurfaced periodically for decades, often promoted as a quick way to drop pounds at home. Registered dietitians who have examined the plan say the short-term results can be misleading and the restrictions leave little room for balanced nutrition.
How the diet works
The traditional version is built around eating large portions of a low-calorie cabbage soup, usually alongside a short list of permitted foods on certain days, such as fruit, vegetables, or meat. Most versions are designed to last only about a week and promise rapid weight loss, much of it water weight rather than fat.
What dietitians point out
Dietitians who have reviewed the plan highlight several recurring concerns, including limited protein, low calorie counts that can slow metabolism, and a structure that is difficult to sustain once normal eating resumes. They also note that the diet can feel monotonous, which makes it harder to stick with and easier to overeat after finishing the cycle.
Comparing it with other approaches
Experts generally favor eating patterns that allow a wider range of foods and can be maintained long term. For readers weighing their options, it helps to see how different methods stack up against each other:

Dietitians often recommend focusing on steady, sustainable habits rather than short, highly restrictive plans. A balanced mix of vegetables, lean protein, whole grains, and regular movement tends to support weight management more reliably than a week-long cabbage soup routine, they say.
