What causes obesity?
Obesity is due to an individual taking in more calories than they burn over an extended period of time. These “extra” calories are stored as fat. Although there are several factors that can lead to this energy imbalance in individuals affected by obesity, the main contributors are behavior, environment and genetics.
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. Based on food choices, many people now select diets that are calorie-rich, but nutrient-poor. This behavioral problem also relates to the increase in portion sizes at home and when dining out.
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 Walking has been replaced by driving cars, basic physical activity has been replaced by technology and nutrition has been overcome by convenience foods.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 will become affected by obesity. Research is currently underway to determine which genes contribute most to obesity.
