Frequently Asked Questions
For Bangladeshi and Asian populations, a BMI between 18.5 and 22.9 is considered healthy. This is slightly lower than the global standard because Asians tend to have higher body fat at the same BMI value.
BMI = Weight (kg) ÷ Height (m)². For example, if you weigh 65 kg and are 170 cm tall: BMI = 65 ÷ (1.70 × 1.70) = 22.5.
BMI is a useful screening tool but not perfect. It does not account for muscle mass, bone density, or fat distribution. Athletes may have a high BMI due to muscle, not fat. Always consult a doctor for a full health assessment.
The global WHO standard considers BMI 25+ as overweight. The Asia-Pacific guideline sets this threshold at 23, because research shows Asians develop obesity-related diseases at lower BMI values than Western populations.
