Several factors contribute to the risk of developing obesity, including genetic predisposition, lifestyle choices, and environmental influences. Poor dietary habits, characterized by high-calorie and low-nutrient foods, greatly affect weight gain. Sedentary behavior, lack of physical activity, and emotional factors such as stress or depression also increase obesity risk. Additionally, socio-economic factors can limit access to healthy foods and safe environments for exercise, exacerbating the problem and making obesity a complex public health challenge.
