The energy needs vary from person to person because of who they are... |
-slight variations in the resting metabolic rate of different people. e.g. muscle needs more energy from fatty tissue, which means people with a higher proportion of muscle to fat in their bodies will have a higher metabolic rate.However, physically bigger people are likely to have a higher metabolic rate than smaller people ( more energy needs because you have more cells) and Men tend to have a slightly higher rate than women (larger proportion of muscle).Regular exercise can boost your resting metabolic rate because it builds muscle. |

Not getting enough exercise and inherited factors... |
Exercise increases the amount of energy used by the body and decreases the amount stored as fat. So people who do regular exercise are less likely to become obese. Some inherited factors cause an under active thyroid gland, which can lower the metabolic rate and cause obesity. Other people may inherit factors that affect their blood cholesterol level which can cause heart disease. |
