Normal weight obesity

Normal Weight Obesity is a medical condition characterized by having a normal body mass index (BMI), but a high body fat percentage. This condition is also known as "skinny fat" or "metabolically obese normal weight."

Definition

Normal weight obesity (NWO) is defined as having a Body Mass Index (BMI) within the normal range (18.5-24.9 kg/m2), but a high body fat percentage. The cut-off for high body fat is typically more than 20% for men and 30% for women.

Causes

The causes of normal weight obesity are not fully understood. However, it is believed to be due to a combination of genetic, environmental, and lifestyle factors. These may include a sedentary lifestyle, poor diet, lack of exercise, and certain medical conditions.

Health Risks

Despite having a normal BMI, individuals with normal weight obesity are at an increased risk of various health problems. These include cardiovascular disease, metabolic syndrome, type 2 diabetes, and cancer. They may also have a higher risk of mortality compared to individuals with a normal BMI and body fat percentage.

Diagnosis

Diagnosis of normal weight obesity is typically made through a combination of BMI measurement and body fat analysis. This can be done through various methods, including bioelectrical impedance analysis, dual-energy X-ray absorptiometry, and skin fold thickness measurements.

Treatment

Treatment for normal weight obesity typically involves lifestyle modifications aimed at reducing body fat and increasing muscle mass. This may include a healthy diet, regular exercise, and potentially medication or surgery in severe cases.
