Obesity is a worldwide problem affecting millions of people with serious consequences for health and quality of life. It occurs when calorie intake exceeds energy intake, leading to excessive accumulation of body fat. This article presents the causes of obesity, the factors that influence it and some effective ways to combat it. This disease is associated with a wide range of medical conditions, a sedentary lifestyle and an unhealthy diet.
