Be aware of the nature of the diet you go on by: Thea
Gaining weight after completing a diet can be annoying. I have found though that it is best to find out what is the true nature of the diet you go on.
For example: Cabbage soup is diuretic so it causes the body to eliminate more urine than regular. Sometimes the body does retain excess water that does not get flushed out as it should.
Cabbage soup diet can cause you to lose too much water if you are not replacing it. I am not a health professional but I find that understanding my body and how it reacts to various diets is the best way to go.
Cabbage soup increases sweating and urine output so losing weight after this diet would indicate that the body might be retaining some excess water. Working with the cabbage soup diet and doing exercises to help the body improve its metabolic rate is my recommended solution.
