What are some of the factors that contribute to overweight and obesity?

Researchers have found that several factors can contribute to the likelihood of someone’s becoming overweight or obese.

Behaviors. What people eat and their level of physical activity help determine whether they will gain weight. A number of factors can influence diet and physical activity, including personal characteristics of the individual, the individual’s environment, cultural attitudes, and financial situation.

Genetics. Heredity plays a large role in determining how susceptible people are to becoming overweight or obese. Genes can influence how the body burns calories for energy and how the body stores fat.
