The body burns about 70 percent of its daily calorie intake when at rest or just breathing, the average daily calorie intake needed for a male is 2500 and 2000 for a woman. This amount can vary depending on the size or age of the individual.
The rate at which the body burns energy is called the metabolic rate. The metabolic rate can vary depending on a person size or how active they are. People who are overweight may cite a low metabolism as a primary reason for weight gain. However, larger people often have a higher metabolism, as it takes more energy to move a heavier body.
