Reason #1
Women naturally store more fat on their bodies than men. A healthy body fat percentage for a woman is between 20%-30%, while the recommended healthy range for a man is between 12%-20%. The reason women store more fat is because a certain amount is necessary to ensure normal ovulation and menstruation. If a woman’s fat percentage drops too low, menstruation will stop and she will become temporarily infertile, so nature puts systems in place (namely hormones) to safeguard against this happening.

Reason #2
Men tend to be bigger than women and therefore have a larger body surface area through which they can lose heat. This loss of body heat results in a slight increase in metabolism as men’s bodies have to work harder than a woman’s to regulate body temperature.

Reason #3
Men tend to have more muscle mass and muscle tissue is metabolically more active than fat tissue – therefore men naturally burn more calories than women even when they are at rest.

Reason #4
Men have higher levels of growth hormone and testosterone than women and these two hormones have a big impact on the rate at which we burn calories.

Reason #5
Physical activity differences appear to play a role too and studies show that women, in general, tend to be less active than men.
