Is 170 lbs overweight for 5'7"?

What the numbers mean for you

You are 10 lbs (4.7 kg) above the healthy upper limit (BMI 25 = 160 lbs (72.4 kg)). At a modest 500 kcal daily deficit (~0.45 kg/week), reaching the healthy range takes about 10 weeks.

You have 22 lbs (9.8 kg) of buffer before crossing into the obese range (BMI 30 = 192 lbs (86.9 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

Population data show that physically active people in this BMI band often have better cardiovascular outcomes than sedentary people inside the 'normal' range.

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 85 cm (34") at 170.2 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

1. Focus on consistency over intensity — small daily wins beat aggressive short-term plans.
2. Track food intake for 1–2 weeks to identify high-calorie patterns.
3. Add strength training to protect lean mass during weight loss.
4. Re-measure waist every month; expect change there before scale weight.
