The root cause of obesity is that energy intake exceeds energy consumption. Heat comes from energy-supplying substances in food: protein (4 kcal/g), fat (9 kcal/g) and carbohydrate (4 kcal/g). The heat consumption is mainly composed of three aspects: basic metabolism, physical activity and food thermal effect. The center of weight loss is to achieve a negative balance of calories (calorie intake is less than calorie consumption). The level of basal metabolism is mainly related to the nutritional status and eating habits of the human body, so not eating after noon is essentially a very harmful way to lose weight. Physical activity and amount of exercise are not the same concept. Scientific research shows that high-intensity exercise is not conducive to losing weight. The thermal effect of food is generally 2~3 hours, which is the theoretical basis for many weight loss experts to say that eating less and eating more meals is beneficial to weight loss.
Weight loss method:
1, scientifically arrange three meals a day
Under normal physiological conditions, most people are used to having three meals a day. The biggest consumption of human body is in the morning of a day. Because after a night of digestion, the stomach has been emptied. If you don't eat breakfast, the energy consumed by the whole morning's activities will be provided by the dinner the day before, which is far from meeting the nutritional needs. Such long-term sterilization is easy to cause acute gastritis, gastric dilatation, acute pancreatitis, coronary heart disease, myocardial infarction and so on. If you eat at night, you will produce excess energy, and the remaining energy will be converted into fat, which is easy to get fat. So don't eat anything within three hours before going to bed is the best way to lose weight, and pay special attention not to drink or eat meat.
2. Control staple food and limit sweets.
If the original food intake is large, the staple food for three meals a day can be reduced by 50 grams. Try to eat less or not to eat too much starch and extremely sweet food, such as sweet potato, potato, lotus root starch, jam, honey, candied fruit, preserved fruit, malt extract, fruit juice candy and so on. Non-staple food can use lean meat, fish, eggs, bean products and vegetables and fruits with low sugar content.
3. Eat more and eat less
In the process of losing weight, it is best to follow the principle of more meals and less meals, and allocate the total amount of food from three meals a day to five meals a day. And the last meal of the day is best eaten 5-6 hours before going to bed.
4. Edible fiber
Dietary fiber can reduce weight: fiber can hinder the absorption of food, absorb water and expand in the stomach, form a larger volume, make people feel full, help reduce food intake, and have a certain effect on weight control. People can digest and absorb food rich in fiber in a certain period of time, and then discharge waste. People who eat more fiber in their diet chew more often, so they eat more slowly. In this way, the small intestine can slowly absorb nutrients, and the blood sugar level is difficult to rise. Because dietary fiber can promote intestinal peristalsis, if eaten in large quantities, constipation will naturally decrease, and the incidence of colorectal cancer will also decrease.
