What is a major risk factor for developing obesity?

Low levels of physical activity are a significant risk factor for developing obesity because physical activity plays a crucial role in maintaining a healthy weight. When individuals are not physically active, they expend fewer calories, which can lead to an energy imbalance. If calories consumed through food exceed the calories burned through daily activities and exercise, the excess energy is stored as fat, leading to weight gain over time.

Conversely, regular physical activity helps to increase calorie expenditure, supports muscle mass, and enhances overall metabolic health. A sedentary lifestyle can also contribute to other risk factors associated with obesity, such as poor dietary choices and metabolic issues. Thus, the lack of movement is directly linked to increased body fat and, consequently, the risk of obesity.
