Everyone knows that eating meat and starchy food is easy to get fat, so we simply give up eating meat and staple food and specialize in vegetables and fruits. Some people don't even eat vegetables, but only eat fruits. I think this is the best way to keep slim. But in fact, it is absolutely impossible to lose weight only by eating fruit, and not all fruits can lose weight. Some fruits have surprisingly high calories. Dr. Li Changping, from the Nutrition Department of Peking Hospital, said that if you eat too many high-calorie fruits such as melons, durians, lychees and longan, especially before going to bed at night, it is easy to cause fat accumulation, which may not only make you lose weight, but also make your weight soar and even get acne. Although some high-fiber fruits can achieve slimming effect in just a few days, if we consume less than 800- 1000 calories every day, it will cause nutritional imbalance and reduce metabolic rate, which is not conducive to weight loss. Moreover, eating only fruit for a long time will lower blood pressure, make women's menstruation irregular, or cause split hair. Just eat fruits and vegetables for a few days, but who can stand it after a long time? So I can't help eating something else, even more than before, so I will gain weight soon. Therefore, weight loss should also be balanced. While eating fruits and vegetables, we should also eat lean meat, cereals, milk, fish and other nutrients.
