Frequently asked questions
What is a healthy BMI range?
A healthy body mass index (BMI) for adults is between 18.5 and 24.9 according to WHO guidelines.
What weight range is considered healthy?
The WHO defines a healthy BMI as 18.5 to 24.9, which for a person 1.75 m tall is about 56.7 to 76.3 kg. Some health bodies use lower thresholds for people of South Asian, Chinese and Japanese descent - often 23 as the overweight cut-off - because cardiometabolic risk rises at a lower BMI in those populations.
Is BMI a good measure of health?
It is a population screening tool, not an individual diagnosis. BMI cannot distinguish muscle from fat, ignores fat distribution, and misclassifies athletes and older adults with low muscle mass. Waist circumference and waist-to-height ratio add useful information about visceral fat that BMI misses entirely.
How fast is it safe to lose weight?
Most guidance suggests 0.5-1 kg per week, produced by a deficit of roughly 500-1,000 calories per day. Faster loss increases the share of lean tissue lost and is harder to sustain. Rate matters less than whether the change is one you can keep, which is why very aggressive targets tend to reverse.
