If you follow the cabbage soup diet properly then you will lose weight.
Cabbage soup is low in calories which means it makes you feel full while allowing you to keep your calorie intake down which helps to burn off fat and cause you to lose weight.
I dropped around 3 lbs of weight in a month when eating cabbage soup and following the cabbage soup diet so it does work but you should also exercise as well because exercise can help you lose more weight and help keep your heart healthy which can lead to a longer life.
