What BMI means

Body Mass Index estimates weight relative to height (kg/m²). It’s a screening tool, not a diagnosis — athletes may read higher due to muscle, and older adults slightly higher. Pair BMI with waist, diet quality and activity for a fuller picture. Use the sugar and NOVA tools to audit packaged foods that influence weight.
