Understanding Your BMI
A BMI in the 18.5-24.9 range is considered healthy by CDC and WHO standards. This range is associated with the lowest risk of cardiovascular disease and type 2 diabetes.
What This Means for Your Height
For women under 5ft 2in, waist-to-height ratio is particularly important. Research suggests that even at a normal BMI, a waist-to-height ratio above 0.5 may indicate increased health risks.
Weight & Threshold
Gaining approximately 4.7 lbs would bring your BMI to 25, the start of the next category.
⬆️ Gaining approximately 4.7 lbs would put you in the Overweight BMI range.
⬇️ Losing approximately 23.2 lbs would bring you to the Underweight BMI threshold.
Waist & Health
The CDC recommends that non-pregnant women keep waist circumference below 35 inches. A waist-to-height ratio below 0.5 is also associated with lower health risks.
Age Context
For children and teenagers (under 18), BMI is interpreted differently. Unlike adults, BMI for youth is age- and sex-specific, using percentiles from CDC growth charts. For a 13-year-old girl at 4ft 7in and 103lbs, a BMI of 23.9 would be evaluated using pediatric growth percentiles rather than the adult normal category.
