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 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
Losing approximately 19.1 lbs would bring your BMI to 40, the boundary of the healthy weight range.
⬇️ Losing approximately 72.0 lbs would bring you to the Overweight 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 adults 65 and older, BMI targets shift. Clinical guidelines (ESPEN, NIH) often recommend a slightly higher BMI range (around 23–26) for seniors to protect against bone loss and muscle decline. At 67 years old, a woman at 5ft 1in and 231lbs has a BMI of 43.6.
Your BMI of 43.6 falls into the Obese category. At age 67, doctors often focus more on mobility, waist size, and functional ability than BMI alone.
