Is 170 lbs overweight for a woman at 5'5"?
Yes — 170 lbs is 20 lbs above the healthy upper limit for 5'5" (for a woman).
At 170 lbs (77.1 kg) and 5'5" (165.1 cm) for a woman, the BMI is 28.3 — overweight.
Someone 165.1 cm tall has a healthy weight window of 111–150 kg, derived from the standard adult BMI range.
What the numbers mean for you
You are 20 lbs (9.0 kg) above the healthy upper limit (BMI 25 = 150 lbs (68.1 kg)). At a modest 500 kcal daily deficit (~0.45 kg/week), reaching the healthy range takes about 20 weeks.
You have 10 lbs (4.7 kg) of buffer before crossing into the obese range (BMI 30 = 180 lbs (81.8 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
This BMI band typically becomes more health-relevant when paired with a waist measurement above 94 cm (men) or 80 cm (women).
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 (33") at 165.1 cm.
- Absolute cutoff for women: waist under 80 cm (31.5") is associated with meaningfully lower risk of type 2 diabetes and cardiovascular disease.
- Higher-risk zone: waist above 88 cm (35") — this is where risk climbs sharply regardless of BMI.
For women at 5'5"
BMI uses the same formula for both sexes, but health interpretation differs. Women typically carry a higher percentage of body fat at the same BMI than men. A waist circumference under 35 inches (88 cm) lowers cardiometabolic risk independent 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.
