Should I exercise more or eat less to lose weight?

Reduced physical activity and abundant energy intake are two most common factors leading to uncontrolled body weight gain.

In addition to these two widely accepted factors, there are some other factors, whose could also contribute to the recent increase of obesity prevalence.
