⬆️ Gaining approximately 15.5 lbs would put you in the Overweight BMI range.
⬇️ Losing approximately 12.5 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 adults 45-64, metabolic health becomes increasingly important. At 51 years old, a woman at 4ft 7in and 92lbs has a BMI of 21.4, which falls into the Normal category.
