Instant answer: A person who weighs 80 kg (176 lbs) and is 180 cm (5'11") tall has a BMI of 24.7, classified as normal weight.

What the numbers mean for you
You have 1.0 kg (2 lbs) of headroom before crossing into overweight (BMI 25 = 81.0 kg (179 lbs)).
Your BMI band midpoint is BMI 21.7 (70.3 kg (155 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 24.7 mean?
Staying inside this band is associated with the most favourable metabolic markers in adult populations under 65.
BMI is a screening tool, not a diagnosis. Two people at 80 kg and 180 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 90 cm (35") at 180 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.
