Heat consumption: Playing badminton consumes about 562 kilocalories an hour, and dancing aerobics consumes about 300 kilocalories an hour. The body "burns" calories in food through metabolism. Metabolism breaks down carbohydrates into glucose and other sugars through enzymes, fats into glycerol and fatty acids, and protein into amino acids. Then, these molecules are transported to cells through the blood stream, where they can be absorbed and utilized immediately, or they can enter the final metabolic stage to react with oxygen and release their stored energy.

Calorie (Cal for short), transliterated from English Calorie, is defined as the heat required to raise 1 gram of water to 1 degree Celsius at 1 atmospheric pressure; Calorie is an energy unit, which is still widely used in nutrition measurement and fitness manual.

Just as computers consume electricity and trucks consume oil, so do human daily activities. Heat not only provides energy for people's exercise, daily work and life, but also provides energy for human life activities, blood circulation, breathing, digestion and absorption. People who lose weight can burn fat through exercise, which can accelerate calorie consumption and achieve the goal of healthy weight loss.
