First of all, dietary fiber can't be digested and absorbed by human body, but it won't produce heat. Eating more dietary fiber can reduce the total calorie intake, and the stomach can feel full after absorbing water, which can effectively prevent overeating. Secondly, if you are often constipated, it will cause obesity. Dietary fiber can promote intestinal peristalsis and accelerate defecation.
Many people think that only high carbohydrate can fill the stomach. In fact, the real main force is protein, protein has a large molecular weight, and it takes longer for the stomach to digest, so the satiety is more lasting.
Vegetables are rich in dietary fiber and vitamins, low in calories, and can also increase satiety and prevent constipation. Want to lose weight, can not do without the help of vegetables. However, it should be noted that some vegetables with high starch content, such as potatoes and sweet potatoes, are only suitable for staple food and not suitable for vegetables.
Many people don't eat staple food during their weight loss, which is a wrong concept. The refined powder of polished rice has a high sugar content, and it is easy to get fat if you eat too much. You can consider using coarse grains rich in dietary fiber instead, and the calories will not be very high.
During weight loss, you must stay away from fried food, otherwise it will be a failure. Fried chicken, hamburgers and other foods smell delicious, but they are typical high-fat and high-calorie foods and are very unhealthy.
