⬆️ Gaining approximately 36.3 lbs would put you in the Overweight BMI range.
⬇️ Losing approximately 19.9 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.
