Causes of Obesity

There are many causes that directly and indirectly contribute to obesity. Behavior, environment, and genetics are among the main contributors to obesity. The Centers for Disease Control has identified these three as the main causes of the complexity of the obesity epidemic.

Behavior

In today’s fast-paced environment, it is easy to adopt unhealthy behaviors. Behavior, in the case of obesity, relates to food choices, amount of physical activity you get and the effort to maintain your health.

Americans are consuming more calories on average than in past decades. The increase in calories has also decreased the nutrients consumed that are needed for a healthy diet. This behavioral problem also relates to the increase in portion sizes at home and when dining out.

While Americans are consuming more calories, they are not expanding them with enough physical activity. Physical activity is an important element in modifying and shaping behaviors. The influence of television, computers and other technologies discourage physical activity and add to the problem of obesity in our society.

Environment

Environment plays a key role in shaping an individual’s habits and lifestyle. There are many environmental influences that can impact your health decisions. Today’s society has developed a more sedentary lifestyle. Walking has been replaced by driving cars, physical activity has been replaced by technology and nutrition has been overcome by convenience foods.

Genetics

Science shows that genetics play a role in obesity. Genes can cause certain disorders which result in obesity. However, not all individuals who are predisposed to obesity become affected by obesity. Research is currently underway to determine which genes contribute most to obesity.
