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.

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 26.5 lbs would bring your BMI to 40, the boundary of the healthy weight range.
⬇️ Losing approximately 79.4 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 45-64, metabolic health becomes increasingly important. At 57 years old, a woman at 5ft 1in and 238lbs has a BMI of 45.0, which falls into the Obese category.
At age 57, maintaining a healthy weight is particularly important. Research shows that adults over 45 with a BMI in the obese range have a significantly higher risk of metabolic syndrome and cardiovascular disease.
