What are the causes of obesity???? :O

The Simple Truth

The core reason people become overweight or obese is fairly simple:

If you take in more calories than are required by your body on a daily basis (known as "energy imbalance"), those surplus calories will be converted into fat.
If this energy imbalance continues for an extended period of time, it will lead to overweight or obesity.
