What is Obesity?
Obesity is defined as excessive fat accumulation that presents health risks. Clinically, it is measured by Body Mass Index (BMI):
Normal weight: BMI 18.5 – 24.9
Overweight: BMI 25 – 29.9
Obese: BMI 30 or more
While BMI is widely used, it does not consider muscle mass, genetics, or fat distribution. That’s why obesity is more complex than just numbers—it’s about overall health.
