First of all, physiology: after entering old age, due to aging, nutrition, activity reduction, etc., easy to occur loss of muscle tissue, resulting in changes in body composition, basal metabolism is also with the increase in age and decline. In addition, with the increase in age, the intestinal digestion and absorption function has a different degree of decline, for certain nutrients absorption, will also be poorer. For example, the absorption of nutrients that build the body's tissue structure is reduced, so it is easier to increase the risk of muscle loss.
Secondly, daily activities: many older people are less active than they were when they were younger, resulting in less energy consumption for daily activities. In addition, physical activity is also reduced for a variety of reasons. For example, two days ago to consult a diabetic elderly, originally maintained the habit of many years jumping in the square dance, recently added a third generation at home, need to help take care of, and had to give up the habit of square dance, very unfortunate.
Based on the above reasons, all of which have resulted in a decrease in the total daily energy consumption of the elderly, so fat.
Why is it said that "a thousand dollars can't buy you"?
First of all, compared to young people, middle-aged and elderly people are more likely to underestimate their own size. A lot of them are already obese and don't consider themselves to be in a state of obesity. Moreover, compared to young people who are keen on "weight loss" and "fitness", middle-aged and elderly people are more keen on "health" and "tonic
And then the old and the middle-aged are more interested in "health" and "tonic" than the young.
Then there is the fact that middle-aged and elderly people are more likely to come to the clinic because of obesity-related complications that have already occurred, rather than because they feel they need to control their weight. Their concerns are also mostly limited to "what can I eat" rather than "what shouldn't I eat".
