Adjust Your Numbers
Change your height or weight to see how your BMI changes.
Understanding Your BMI
A BMI of 30 or above indicates obesity. The CDC reports that this range is associated with a 50-60% higher risk of cardiovascular disease and type 2 diabetes. Comprehensive lifestyle intervention and medical guidance are strongly recommended.
What This Means for Your Height
For men of average height, BMI is a reliable screening tool. The CDC recommends keeping waist circumference below 40 inches to minimize health risks.
Weight & Threshold
Gaining approximately 51.9 lbs would bring your BMI to 40, the start of the next category.
⬇️ Losing approximately 6.4 lbs would bring you to the Overweight BMI threshold.
Waist & Health
The CDC recommends that men keep waist circumference below 40 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 17-year-old boy at 5ft 4in and 181lbs, a BMI of 31.1 would be evaluated using pediatric growth percentiles rather than the adult obese category.
