A calorie is a unit of energy that the body needs to move and maintain its temperature. The nutrients we take into our body turn into energy, but excess calories turn into fat molecules and cause the body to store fat.
The essential nutrients our body needs to produce energy are:
- Protein: 4 calories per gram
- Carbohydrate: 4 calories per gram
- Fat: 9 calories per gram
1 kilogram of body weight is approximately equivalent to 7700 calories. This means:
- If you consume 7700 calories, you will gain 1 kilogram.
- If you expend 7700 calories, you will lose 1 kilogram.
