Is 170 lbs overweight for 5'6"?
Yes — 170 lbs is 16 lbs above the healthy upper limit for 5'6".
At 170 lbs (77.1 kg) and 5'6" (167.6 cm), the BMI is 27.4 — overweight.
For an adult who is 167.6 cm tall, the World Health Organization considers a weight between 115 and 154 kg to be healthy.
What the numbers mean for you
You are 15 lbs (6.9 kg) above the healthy upper limit (BMI 25 = 155 lbs (70.2 kg)). At a modest 500 kcal daily deficit (~0.45 kg/week), reaching the healthy range takes about 15 weeks.
You have 16 lbs (7.2 kg) of buffer before crossing into the obese range (BMI 30 = 186 lbs (84.3 kg)). A 5–10% weight reduction (8 lbs (3.9 kg) to 17 lbs (7.7 kg)) 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
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 84 cm (33") at 167.6 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.
