Is 80 kg overweight for 170 cm?
Yes — 80 kg is 8.0 kg above the healthy upper limit for 170 cm.
At 80 kg (176 lbs) and 170 cm (5'7"), the BMI is 27.7 — overweight.
Public-health guidelines place the ideal weight for 170 cm tall adults at 53.5–72 kg, equivalent to a BMI between 18.5 and 24.9.
What the numbers mean for you
You are 7.7 kg (17 lbs) above the healthy upper limit (BMI 25 = 72.3 kg (159 lbs)). At a modest 500 kcal daily deficit (~0.45 kg/week), reaching the healthy range takes about 17 weeks.
You have 6.7 kg (15 lbs) of buffer before crossing into the obese range (BMI 30 = 86.7 kg (191 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 this means for your health
At this BMI level, fitness and waist circumference are arguably more predictive of metabolic health than the BMI number itself.
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.

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.
