A sedentary lifestyle

Modern life has made us comfortable and stationary. For example, public transportation has replaced walking, and screen time has replaced physical hobbies. Many jobs today involve sitting in front of a computer or at a desk for long hours, reducing physical activity that can lead to weight gain.

Poor dietary choices

Consuming a diet high in calories, saturated fats, and sugars with little nutritional value, such as fast food and snacks, can lead to obesity and other chronic diseases. On the other hand, a balanced diet rich in nutrient-dense whole foods, protein, and fruits and vegetables, can help individuals maintain a healthy weight.


Genetics can also play a role in the development of obesity. If one or both parents are obese, there is a higher probability that their children will also be obese. Scientists have identified the FTO gene, which confers a higher risk of developing obesity.

Medical conditions and medication

Certain medical conditions, such as hypothyroidism and Cushing’s syndrome, and medications such as antidepressants and corticosteroids, can cause weight gain

Environmental factors

Environmental factors may also contribute to obesity. Exposure to pollution and other toxins can interfere with metabolic function, and the built environment in some areas may limit people’s access to healthy foods and places to exercise
