Female: basic calories = weight (kg) x 9
Man: Basic calories (calories) = weight (kg) x 10.
2, need heat
Daily calorie requirement of adults = basic calorie required for basic metabolism of human body+calorie required for physical activity+calorie required for digestion of food.
Heat required for digesting food = 10% x (minimum heat required for basic metabolism of human body+heat required for physical activity)
Daily caloric requirement of adults = 1. 1 x (minimum basal caloric requirement for basic metabolism of human body+caloric requirement for physical activity).
Generally speaking, adults need at least 1500 kcal of energy every day to maintain body function, because even if you lie still, your body still needs energy to maintain body temperature, cardiopulmonary function and brain operation.
Extended data thermal effect
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.
metabolism
Generally speaking, adults need at least 1500 kcal of energy every day to maintain body function, because even if you lie still, your body still needs energy to maintain body temperature, cardiopulmonary function and brain operation. Basal metabolic consumption varies with individual height, weight, age and gender. Human survival needs energy, which is obtained from food.
The calorie content in food is a measure of how much potential energy food produces. 1g carbohydrate has 4000 calories, 1g protein has 4000 calories, and 1g fat has 9000 calories. Food is generally composed of these three substances. Therefore, as long as we know the contents of these three substances in food, we can know how much heat or energy food contains.
