If you want to lose weight, it is better to eat some fruit after meals, and the effect of eating apples to lose weight is also quite good, because apples themselves are better fruits to lose weight, so you must control your diet at ordinary times. However, some people can eat some fruits and apples properly before meals, which can not only fill their stomachs, but also reduce the intake of staple foods and help them lose weight. In addition, after eating fruit, the fructose contained in it can not enter the intestine in time, so it will ferment in the stomach and produce organic acids, which will cause abdominal distension and diarrhea. So wait an hour after dinner before eating fruit.
