The Body Mass Index (BMI) Calculation
The Body Mass Index (BMI) is the easiest way to assess obesity. With this calculation, you may measure your BMI: (BMI= weight in kilograms / height in meters2).
You're considered healthy if your BMI is 20-23. The BMI of an overweight person ranges between 23-27, while an obese person has a BMI between 27-40.
A bariatric surgery is recommended if you are morbidly obese and BMI over 35. If you have weight-related metabolic syndrome, surgery for those with BMI>27 is advised.
