BMI for 80 kg and 168 cm
Instant answer: A person who weighs 80 kg (176 lbs) and is 168 cm (5'6") tall has a BMI of 28.3, classified as overweight.
For an adult who is 168 cm tall, the World Health Organization considers a weight between 52.2 and 70.3 kg to be healthy.
What the numbers mean for you
You are 9.4 kg (21 lbs) above the healthy upper limit (BMI 25 = 70.6 kg (156 lbs)). At a modest 500 kcal daily deficit (~0.45 kg/week), reaching the healthy range takes about 21 weeks.
You have 4.7 kg (10 lbs) of buffer before crossing into the obese range (BMI 30 = 84.7 kg (187 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 28.3 mean?
This BMI band typically becomes more health-relevant when paired with a waist measurement above 94 cm (men) or 80 cm (women).
BMI is a screening tool, not a diagnosis. Two people at 80 kg and 168 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 84 cm (33") at 168 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
- Focus on consistency over intensity — small daily wins beat aggressive short-term plans.
- Track food intake for 1–2 weeks to identify high-calorie patterns.
- Add strength training to protect lean mass during weight loss.
- Re-measure waist every month; expect change there before scale weight.
