Walking after meals not only helps to digest food and reduce the burden on the digestive system, but also helps to reduce the accumulation of abdominal fat and effectively consume energy intake. Long-term persistence will have a certain effect on reducing abdominal fat. In addition, you can do some abdominal massage every day, and insist on massaging the abdomen every day, which can not only promote defecation, but also help to eliminate abdominal fat. In addition, it should be noted that the digestive and metabolic function of the elderly will decline with the increase of age, so if the diet consumes too much energy, it will cause fat accumulation. For the elderly aged 60 ~ 69, the daily energy intake should be reduced by 15%. For the elderly aged 70 ~ 79, it is best to reduce energy intake by 25% every day, which is helpful to eliminate abdominal fat.
