Weight is a key factor in how the elderly live longer. In the past, health science asked everyone to talk about obesity, because obesity is closely related to the risk of a series of chronic diseases.
However, in recent years, there have been different voices that the elderly are slightly fat, which means that the elderly should be generous, but not big. It means that the elderly should not hold back on things, but remember: it is difficult to buy old and thin with a thousand dollars.
Muscles of human body generally account for 1/3 or 1/2 of body weight, and all kinds of sports are inseparable from the support of muscles, which is equivalent to the executor of the heart. But at the age of 30, human muscles will decline at the rate of 1% ~ 2% per year. By the age of 80, nearly 50% of the muscles will be lost, the muscle quality will decrease, and the strength will also decrease.
If we compare the human body to a tall building, muscles are like bricks filling the walls. If bricks are short, too fast or damaged, they will easily collapse, and muscles are no exception.
The healthiest body fat rate:
The range of health depends on the individual's age, but it is 2 1% ~ 36% for women and 12% ~ 25% for men. This will be used to determine whether you already have a healthy body fat percentage. If your body fat percentage is above the indicated health range, you may want to reduce it as part of your health and fitness plan.
In order to be healthy, women need a higher proportion of fat than men. Women need more fat to ovulate and protect the uterus. Breast tissue is mainly composed of fat. For men, fat is mainly stored in the abdomen, but abdominal fat is bad fat, so the percentage of fat in men is low.
The energy or heat needed by the body comes from diet. Once the heat is available, the body will run in the supply and demand system. The food you eat "supplies" the "needs" of your body's daily exercise and activities, and all the calories will be converted into the energy needed by your body.
However, if you provide your body with more calories than it needs, the excess calories that are not consumed by activities will be stored in fat cells. If these stored fats are not converted into energy in the future, they will produce excess body fat.
