Is 80 kg overweight for 180 cm?

No — 80 kg is within the healthy range for 180 cm.

At 80 kg (176 lbs) and 180 cm (5'11"), the BMI is 24.7normal weight.

At 180 cm, the BMI-based healthy weight range spans 60 kg to 80.9 kg. No single point inside that band is established as individually optimal.

BMI scale WHO BMI categories from 14 to 42 with a marker at 24.7. Under Normal Over Ob I Ob II+ BMI 24.7 14 42
Your BMI of 24.7 sits in the normal weight band. Cutoffs: 18.5, 25, 30, 35 (WHO).

What the numbers mean for you

You have 1.0 kg (2 lbs) of headroom before crossing into overweight (BMI 25 = 81.0 kg (179 lbs)).

The arithmetic midpoint of the healthy band at this height is BMI 21.7 (70.3 kg (155 lbs)). That is a midpoint, not a target: there is no evidence that any specific point inside the healthy range is individually optimal.

Timelines assume ~7,700 kcal per kg of body fat. Real progress varies with muscle mass, adherence, and medications.

What this means for your health

Staying inside this band is associated with the most favourable metabolic markers in adult populations under 65.

Waist adds information BMI cannot

Two people can share the same BMI and carry very different amounts of abdominal fat. Waist circumference captures that difference, which is why clinical guidance (NICE CG189, WHO 2008) recommends reading it alongside BMI rather than instead of it.

  • Waist-to-height rule: guidance suggests keeping waist below half your height — below 90 cm (35") at 180 cm.
  • Sex-specific thresholds: increased risk from 94 cm (37") for men and 80 cm (31.5") for women; substantially increased risk from 102 cm (40") and 88 cm (34.6") respectively. There is no unisex waist threshold.
  • What it does not do: waist is another screening measurement. It does not diagnose anything. These waist cut-offs were derived mainly from European-origin populations. WHO notes that equivalent risk occurs at lower waist values in South Asian, Chinese, Japanese and other Asian populations, so they are population-specific rather than universal. The waist-to-height rule above is the more portable check (NICE NG246, for adults with a BMI below 35).

Practical next steps

  1. This BMI band is the one associated with the lowest all-cause mortality in large cohort studies.
  2. Protein intake around 0.8–1 g per kg is the commonly cited maintenance figure for adults.
  3. Waist circumference often changes before scale weight does as people age.
  4. A healthy BMI does not rule out raised blood pressure, glucose or lipids; those need measuring separately.
