Low-fat and high-calcium milk has a certain weight loss effect, but it should be eaten for a long time. Drinking low-fat and high-calcium milk will not only increase nutrition, but also not gain weight. In addition, eat less oily, salty and sweet foods, especially fatty meat, animal liver, pickles, cakes and other foods, and exercise properly during weight loss. You can eat more vegetables rich in vitamins such as celery, cucumber and tomato.
