Weight control is instead for the general population. Traditionally, the understanding of weight control is to exercise more and eat less, but for patients with osteoarthritis excessive exercise may aggravate the symptoms, so we should emphasize exercise, diet, behavior (lifestyle habits) emotional unity to achieve the goal of physical and mental harmony and weight control. In fact, nowadays, the standard of living has improved, so we can choose food, control staple foods, and increase the proportion of fruits, vegetables, and nuts. The proportion of fruits, vegetables and nuts.

The third aspect of the diet is long-term stability, not overeating. So far the details of food, disease prevention, tumor prevention and so on the role of a variety of materials on many can not be fully believed, seriously bad food not to eat, the other seems to be acceptable a little. Some points to note on the diet: 1, do not easily diet, weight control successful people do not diet, but do not eat high fat, desserts and snacks; 2, to be realistic, hoping to reduce weight to an impossible degree is doomed to failure, the correct approach is to set a realistic goal at the beginning, so that the weight gradually and slowly reduce; 3, do not quit meals, eat 3 meals a day, than People who do not eat meals consume 10% more calories, because every time people eat, their metabolism will accelerate, that is, if you quit meals, the body will lower the metabolic rate of the way to compensate; 4, eat slowly, to chew slowly to enjoy every bite of food, to lose weight should always be the last to finish eating. People who wolf down food are not easy to produce a sense of satiety after eating, and will eat more food; 5, moderate increase in the proportion of starchy foods, complex carbohydrates contain only a small amount of fat, sugar and calories, is a good food to control weight. Should increase the proportion of potatoes, rice, flour and corn and other complex carbohydrate components in the diet, but note that the concept of increase here refers to the daily food ration, not to increase the amount of food intake; 6, failure is the mother of success, weight loss can rarely be achieved overnight, from the experience of the most successful weight loss, are through unremitting efforts to find a most effective way to lose weight for themselves, to have a strong and unwavering The belief to fight a long-lasting battle.

Both of these aspects can affect weight control from the side, so it is clear that physical and mental harmony is also very important for weight control.
