Hello. Eating about 3500 calories a day can make you lose a pound. Under normal circumstances, if you want to lose a pound of fat, the average person needs to consume about 3500 calories. So it also means that as long as the average person consumes 3500 calories, he will gain a pound appropriately. Whether you lose weight through exercise or dieting, you follow such a rule: the calories consumed by the human body = the basic calories needed for basic metabolism of the human body+the calories needed for physical activities+the calories needed for digesting food. Among the calories consumed by the human body, the most important thing is the basic metabolism of the human body, which is relatively stable at a certain age. The three parts behind the equal sign in the formula consume heat, and the heat required for physical activity is the most controllable change. Therefore, in order to increase calorie consumption and improve the effect of weight loss, it is necessary to improve basal metabolism and increase physical activity. The best way to improve basal metabolism is exercise, and the best way to increase physical activity is exercise. In other words, if you want to lose weight as soon as possible, exercise is necessary. 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. The international standard unit of energy is joule. As the legal unit of food calories, joules are widely used in Europe, while calories are used in the United States. Although Joule is the legal unit in Chinese mainland and Taiwan Province Province, it is still widely used in Chinese mainland and Taiwan Province Province because of tradition. Chinese name: calories. Mbth: calories. Calories: units of energy. Unit: cal. I wish you all the best, health, happiness and happiness. Please adopt it. Thank you.
