BMI for 85 kg and 172 cm
Instant answer: A person who weighs 85 kg (187 lbs) and is 172 cm (5'8") tall has a BMI of 28.7, classified as overweight.
Public-health guidelines place the ideal weight for 172 cm tall adults at 54.7–73.7 kg, equivalent to a BMI between 18.5 and 24.9.
What the numbers mean for you
You are 11.0 kg (24 lbs) above the healthy upper limit (BMI 25 = 74.0 kg (163 lbs)). At a modest 500 kcal daily deficit (~0.45 kg/week), reaching the healthy range takes about 24 weeks.
You have 3.8 kg (8 lbs) of buffer before crossing into the obese range (BMI 30 = 88.8 kg (196 lbs)). A 5–10% weight reduction (4.3 kg (9 lbs) to 8.5 kg (19 lbs)) is clinically meaningful even without reaching a "normal" BMI.
Timelines assume ~7,700 kcal per kg of body fat. Real progress varies with muscle mass, adherence, and medications.
What does a BMI of 28.7 mean?
At this BMI level, fitness and waist circumference are arguably more predictive of metabolic health than the BMI number itself.
BMI is a screening tool, not a diagnosis. Two people at 85 kg and 172 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 86 cm (34") at 172 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.

Practical next steps
- Aim for 5–10% body-weight reduction as the first goal — this alone improves most metabolic markers.
- Walk 30+ minutes daily and add two resistance sessions weekly.
- Audit liquid calories; they are the easiest to cut.
- Discuss screening for blood pressure, glucose, and lipids with your GP.
