Body mass index (BMI) alone does not accurately measure obesity or health risk, as it does not distinguish between fat and muscle mass.
A higher weight can indicate more muscle, which is beneficial, while a normal BMI may still hide excess fat, particularly around the waist, which is linked to disease. More precise methods, such as waist circumference, waist-to-hip ratio, and imaging scans, better assess body fat and its associated health risks.
Experts now define obesity not just by weight but by excess fat mass that affects organ function and increases the risk of chronic conditions like heart disease, diabetes, and stroke.
To assess obesity properly, a medical evaluation should include medical history, physical exams, and lab tests for blood sugar, cholesterol, and organ function. Treatment should focus on improving or reversing obesity-related health complications rather than just reducing weight.
Lifestyle changes, medication, psychological support, or surgery may be considered based on individual risks and benefits. Regular exercise, including aerobic and strength training, is recommended to maintain a healthy body composition and reduce disease risk.
