First of all, let's not discuss whether this "witch soup" slimming method is scientific and feasible. Let's first analyze the ingredients used and the operation methods. The whole food of the witch slimming soup is: 2 to 3 tomatoes, 1 whole cabbage, 2 green peppers, 1 a handful of celery and 2 onions. The operation method is: put the above-mentioned food into a large pot and cook until all the dishes are soft, only add salt without oil, except for a few Chinese fruits and vegetables recommended to eat every day. If you are hungry, drink soup and don't eat residue. All the ingredients used provide about 560 kilocalories of energy. But 95% of the nutrition in the soup is in the soup residue, which has to question the nutritional value of this cauldron of "witch soup".
