Obesity tends to run in families, or descendants. If one parent has excess weight, then the child is also at risk of experiencing the same thing. It is uncertain, but the trend is there and often appear in life and our everyday environment.

- Gender factors.
Women are prone to obesity than men. This is because men have a higher metabolic rate than women, even when resting/sleeping. That means men need more calories to the body. Also, when a woman enters menopause metabolic rate decreases. Because it’s quite a lot of women that become obese after menopause.

Someone who is physically active requires more calories than people who are less active. People who every day are always physically active will burn more calories, and will even use body fat for energy if calories in the body are not sufficient.

Several types of medicines can also lead to excess weight gain, such as steroids and some antidepressants.
