Causes of Obesity

 

There are many factors that contribute to causing obesity including genetics, the environment and behavior.

1-Genes
 

Some individuals have a genetic tendency to gain weight and store fat. Although not everyone with this tendency will become obese, some persons without genetic predisposition do become obese. Several genes have been identified as contributors to obesity, and researchers are constructing a Human Obesity Gene Map in hope of finding genetic targets in humans that may lead to the development of new treatments.

 

2-Environment:
 

An environment that promotes healthy weight is one that encourages consumption of nutritious foods in reasonable portions and regular physical activity. A healthy environment is important for all individuals to prevent and treat obesity and maintain weight loss.

Healthy environments can be created at home, school, work and beyond. Identifying and consciously avoiding high-risk situations in the environment can assist in weight control efforts.

3-Behavior
 

Adopting healthy habits for lifelong weight control purposes includes regular physical activity and nutritious eating.

Specific behavioral strategies for weight loss and maintenance include: logging and tracking diet and exercise patterns in a diary, eating a low calorie diet, limiting the amount of calories from fat, expending calories routinely through exercise, monitoring weight regularly, setting realistic goals, and developing a social support network.
