Eating chocolate can really lose weight, mainly because of the cocoa content of chocolate. According to the article I read on the online food safety website, chocolate can lose weight because the fat content of pure cocoa beans is not high. Its caffeine can inhibit people's appetite, and its phenylethanol can also make the brain produce substances similar to those secreted in love, which makes people feel happy and satisfied. In addition, it contains isoflavones, which can prevent water accumulation in the body and avoid edema. The method is: 1, try to choose chocolate with high cocoa butter content and low sugar content, which can prevent you from eating too much sugar. In this respect, dark chocolate is better than ordinary milk chocolate and nut chocolate. However, Jiuxin chocolate is not high in calories, only about 400 calories per gram of 100, but its sugar content can be as high as 72.2% and its fat content is only 12%, which is not a good choice. 2, to control the amount of food, how much to eat at the same time, we must subtract the corresponding calories. A simple reference is that 100 grams of chocolate can reach about 600 calories, while 1 bowl of white rice has a calorie of about 250ml, two sweet biscuits have a calorie of 185 calories, and 1 fried eggs have a calorie of 136 calories. 3. You can eat something before exercise. If you eat a little chocolate before exercise, you can increase the glycogen storage in muscles, help improve your exercise ability, save glycogen consumption, delay fatigue, and help restore glycogen after long-term exercise. At the same time, because you want to exercise in the future, you don't have to worry about getting fat.
