Question

What is obesity? What ar its causes

Answer 1

A disorder involving excessive body fat that increases the risk of health problems.Causes of obesity. Obesity is generally caused by eating too much and moving too little. If you consume high amounts of energy, particularly fat and sugars, but don't burn off the energy through exercise and physical activity, much of the surplus energy will be stored by the body as fat

Answer 2

obeisity is caused due over eting of junk and fatty food that contain high amount of calories...these calories are a great reason for fatness...
obesity has reached epidemic proportions in populations whose environments promote physical inactivity and increased consumption of high-calorie foods.....However, not all people living in such environments will become obese, nor will all obese people have the same body fat distribution or suffer the same health problems. These differences can be seen in groups of people with the same racial or ethnic background and even within families.... Genetic changes in human populations occur too slowly to be responsible for the obesity epidemic.... Nevertheless, the variation in how people respond to the same environment suggests that genes do play a role in the development of obesity.
