BMI for 80 kg and 172 cm
Instant answer: A person who weighs 80 kg (176 lbs) and is 172 cm (5'8") tall has a BMI of 27.0, classified as overweight.
For an adult who is 172 cm tall, the World Health Organization considers a weight between 54.7 and 73.7 kg to be healthy.
What the numbers mean for you
You are 6.0 kg (13 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 13 weeks.
You have 8.8 kg (19 lbs) of buffer before crossing into the obese range (BMI 30 = 88.8 kg (196 lbs)). A 5–10% weight reduction (4.0 kg (9 lbs) to 8.0 kg (18 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 27.0 mean?
A BMI in this band is moderately associated with elevated blood pressure and altered lipid profiles, but lifestyle factors strongly modify the actual risk.
BMI is a screening tool, not a diagnosis. Two people at 80 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
- Create a modest caloric deficit of 250–500 kcal/day for steady, sustainable loss.
- Combine cardio with strength training to preserve muscle.
- Track waist measurement — it often improves before scale weight.
- Reduce ultra-processed foods and sugar-sweetened drinks first.
