What it is

BMI (Body Mass Index) is weight divided by height squared. It's a screening number, not a body fat measurement, but a quick signal of whether your weight is in a healthy range for your height.

Why it matters

Tracking BMI over months reveals directional change that individual weigh-ins can hide. Pair it with photos and you'll see when the number reflects real fat loss versus water weight swings.

BMI doesn't distinguish fat from muscle. Athletes often score "overweight." Use it as one data point, not a verdict. This tool provides general health information, not medical advice.
