Frequently Asked Questions
Is every weight inside this range equally healthy?
The range is a population guideline, not a personal prescription. Factors like muscle mass, age and ethnicity shift where within the band an individual does best.
Why use BMI 18.5 to 24.9?
Large cohort studies show the lowest all-cause mortality in this band for most adults, which is why the WHO adopted it as the normal-weight category.
How fast should I move toward my healthy weight?
A loss or gain of 0.25-0.5 kg (0.5-1 lb) per week is generally sustainable. Faster changes tend to cost you muscle or rebound quickly.
