Chinese cabbage, green vegetables and spinach can be eaten raw as long as they are boiled rather than fried, and they can lose weight regardless of each other. If you fry in oil, especially if you put a lot of oil, no vegetable will lose weight.
If you want to lose weight, you can eat all kinds of sugar-free vegetables to keep your body balanced. If the body is not balanced in nutrition, it is also the cause of getting fat.
