Energy requirements tend to be higher for men as they tend to be heavier with greater muscle mass than women with lower levels of fat. Women tend to have a higher percentage of body fat which is important for reproduction and to make female hormones in the body. Muscle is metabolically active and therefore requiring energy, whereas fat is not metabolically active which is the reason for gender differences. Energy requirements will vary depending on someone’s body size, age, gender, occupational activity levels and also energy used in physical activity. If an individual is very active then their energy requirements will be much higher.
