Obesity is a complex condition caused by a combination of genetic, dietary, and lifestyle factors.

The FTO gene is the most strongly associated genetic factor with obesity, with variations in this gene linked to increased body fat accumulation.

A diet high in processed foods, sugary beverages, and low in fruits and vegetables is associated with an increased risk of obesity.

Physical inactivity, sedentary behavior, and insufficient sleep are all lifestyle factors that contribute to obesity.

Obesity is a major risk factor for cardiovascular disease, type 2 diabetes, and stroke.

Obesity increases the risk of cardiovascular disease by increasing blood pressure, elevating cholesterol levels, and promoting inflammation.

Obesity contributes to type 2 diabetes by causing insulin resistance, impaired glucose tolerance, and increased inflammation.

Obesity increases the risk of stroke by increasing blood pressure, promoting atherosclerosis, and causing atrial fibrillation.

Leptin is a hormone produced by fat cells that signals the brain to suppress appetite and increase energy expenditure.

Ghrelin is a hormone produced by the stomach that stimulates appetite and increases food intake.

Insulin is a hormone that promotes the storage of glucose as fat in adipose tissue.

Hepatic steatosis, non-alcoholic fatty liver disease, and cirrhosis are all terms used to describe the abnormal accumulation of fat in the liver.

Visceral obesity, also known as central obesity, is characterized by an accumulation of fat in the abdominal region, particularly around the internal organs.

Gastric bypass surgery, sleeve gastrectomy, and bariatric surgery are all surgical procedures used to treat obesity by reducing the size of the stomach or altering the digestive system.

Adults should engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, or a combination of both, to maintain a healthy weight.
