What a BMI of 15.7 at 5'10" and 110 lbs means

A BMI of 15.7 at 5'10" and 110 lbs falls into the severe thinness range (below 16). This level carries a meaningfully elevated risk of nutrient deficiencies, weakened immunity, and complications such as anemia, osteoporosis, and amenorrhea in women.

For someone 5'10" tall, the WHO healthy BMI range (18.5 โ€“ 24.9) corresponds to a body weight between roughly 58.6 โ€“ 78.9 kg (129.2 โ€“ 173.9 lbs). BMI is a screening tool, not a body composition measurement, so it does not distinguish muscle from fat. Pair it with waist circumference and body fat percentage for a complete picture.

Frequently asked questions

Is a BMI of 15.7 healthy for 5'10"?
A BMI of 15.7 at 5'10" is classified as Severely Underweight. The WHO healthy BMI range is 18.5 โ€“ 24.9, which for your height translates to roughly 58.6 โ€“ 78.9 kg (129.2 โ€“ 173.9 lbs).
What is the ideal weight for someone 5'10" tall?
The mid-point of the healthy BMI range (BMI 22) for 5'10" is approximately 69.7 kg (153.7 lbs). The full healthy range spans roughly 58.6 โ€“ 78.9 kg. Body composition matters more than the exact number โ€” a muscular person can sit at the top of the range and be perfectly healthy.
How does BMI relate to body fat percentage at 110 lbs?
BMI does not measure body fat directly. Two people at 5'10" and 110 lbs can have very different body compositions. A trained athlete at this weight may have 12 โ€“ 15% body fat, while a sedentary adult may have 25 โ€“ 30%. Use the Body Fat Calculator for a more precise estimate.
Is BMI accurate for everyone at 5'10" tall?
BMI is a population-level screening tool. It systematically over-classifies muscular athletes as overweight and under-classifies older adults with sarcopenic obesity. For an individual assessment at 5'10", combine BMI with waist circumference (men < 94 cm, women < 80 cm at low risk) and body fat percentage.
How much weight would I need to lose or gain to reach a healthy BMI at 5'10"?
If your BMI is below 18.5, gaining weight up to the 58.6 kg (129.2 lbs) threshold puts you in the healthy band. If above 25, losing weight toward 78.9 kg (173.9 lbs) does the same. Aim for 0.25 โ€“ 0.5 kg per week for sustainable change.
