Generally speaking, about 7,000 calories are equal to 1 kilogram of fat.
Carbohydrates, fats and proteins are the main sources of calories. The calories they provide are 4 kcal, 9 kcal and 4 kcal per gram respectively. Nutritionists have proposed to calculate the relationship between our body and diet. The relationship between calories is as follows:
Each kilogram of fat on our bodies contains 7,000 calories, which means we must consume 7,700 calories to lose 1 kilogram.
Every person needs at least 30 calories per kilogram of body weight per day, which means that a 50-kg person needs 1,500 calories a day to supplement the functioning of the body without doing any exercise. calories consumed.
Calorie is a unit of energy. We tend to associate calories with food, but they actually apply to anything that contains energy.
Simply put, 1 calorie of energy or heat can raise the temperature of 1 gram of water by 1 degree Celsius at one atmosphere of pressure. 1 calorie is approximately equal to 4.186 joules (joules are a commonly used unit of energy in physics).

"Required calories" relative to the heat release formula
The daily calories required by adults = the basic calories needed for the human body's basal metabolism + physical strength Calories required for activity + Calories required for digesting food.
Calories needed to digest food = 10% x (minimum calories required for human basal metabolism + calories required for physical activity)
Daily calories required for adults = 1.1 x (Minimum basic calories required for basal metabolism of the human body + calories required for physical activity)
Men: 9250-10090 kilojoules
Female: 7980-8820 kilojoules
p>Note: The daily calories provided by food should be no less than 5,000 kilojoules - 7,500 kilojoules. This is the minimum energy required to maintain normal life activities of the human body
The needs of the human body's basal metabolism Simple algorithm of basic calories
Women: Basic calories (kcal) = Body weight (jin) x 9
Men: Basic calories (kcal) = Body weight (jin) x 10
