BMI for 80 kg and 165 cm
Instant answer: A person who weighs 80 kg (176 lbs) and is 165 cm (5'5") tall has a BMI of 29.4, classified as overweight.
Public-health guidelines place the ideal weight for 165 cm tall adults at 50.4–67.8 kg, equivalent to a BMI between 18.5 and 24.9.
What the numbers mean for you
You are 11.9 kg (26 lbs) above the healthy upper limit (BMI 25 = 68.1 kg (150 lbs)). At a modest 500 kcal daily deficit (~0.45 kg/week), reaching the healthy range takes about 26 weeks.
You have 1.7 kg (4 lbs) of buffer before crossing into the obese range (BMI 30 = 81.7 kg (180 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 29.4 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 165 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 83 cm (32") at 165 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.
