Cabbage soup diet for weight loss

The cabbage soup diet might be one of the most confusing weight loss trends I've come across.

On one hand, people swear they dropped 5–10 pounds in a week eating mostly cabbage soup. On the other hand, almost everyone seems to admit the weight comes back as soon as they start eating normally again.

What surprised me is that the diet isn't really about cabbage. It's basically an extremely low-calorie diet disguised as a "special" food plan. If you eat the same soup all day, you're naturally going to eat fewer calories.

The weird part is that people often call it a detox. But does eating one vegetable over and over really "cleanse" anything, or does it just create a calorie deficit and some temporary water weight loss?

I'm not saying cabbage is bad. It's cheap, filling, and pretty nutritious. I just don't know if building an entire diet around one soup is the answer.

Has anyone here actually done the cabbage soup diet and kept the weight off long-term?
