BMI for 70 kg and 170 cm
Instant answer: A person who weighs 70 kg (154 lbs) and is 170 cm (5'7") tall has a BMI of 24.2, classified as normal weight.
At 170 cm, the BMI-based healthy weight range spans 53.5 kg to 72 kg, with the midpoint considered the most statistically protective.
What the numbers mean for you
You have 2.3 kg (5 lbs) of headroom before crossing into overweight (BMI 25 = 72.3 kg (159 lbs)).
Your BMI band midpoint is BMI 21.7 (62.7 kg (138 lbs)), often used as the "most protective" reference in cohort studies.
Timelines assume ~7,700 kcal per kg of body fat. Real progress varies with muscle mass, adherence, and medications.
What does a BMI of 24.2 mean?
Within this range, body composition matters more than the exact number — muscle mass and waist circumference become the better health signals.
BMI is a screening tool, not a diagnosis. Two people at 70 kg and 170 cm can have very different body compositions and very different health profiles. Use BMI alongside waist circumference, fitness level, and routine bloodwork.
Waist matters more than the scale
Two people can share the same BMI and have very different metabolic risk. For that reason, waist circumference is now considered a stronger predictor of cardiometabolic disease than BMI alone.
- Waist-to-height rule: keep your waist under half your height — that means below 85 cm (33") at 170 cm.
- Absolute cutoff for most adults: waist under 94 cm (37") is associated with meaningfully lower risk of type 2 diabetes and cardiovascular disease.
- Higher-risk zone: waist above 102 cm (40") — this is where risk climbs sharply regardless of BMI.
