The BMI for 55 kg weight and 170 cm height is 19 — Normal weight on the standard WHO scale and Normal weight on the Indian/Asia-Pacific scale. The healthy weight for 170 cm is 53.5–72 kg (WHO BMI 18.5–24.9), or the stricter 53–66 kg (Indian BMI 18.5–22.9) recommended by the ICMR.
BMI 19 on both classification scales
WHO / International
Asia-Pacific / India (ICMR)
A BMI of 19 is classified as Normal weight internationally and Normal weight under the lower Indian cutoffs, which flag health risk from a BMI of 23 rather than 25.

At 55 kg you are inside the healthy WHO range of 53.5–72 kg for 170 cm.
Maintaining 55 kg at 170 cm
At 55 kg you are already inside the healthy WHO range of 53.5–72 kg for 170 cm, so the goal is maintenance. Eating near your maintenance calories, staying active, and keeping up strength work will hold your weight steady.
Estimated daily calories at 55 kg / 170 cm
Men (maintenance)
2275 kcal/day
BMR 1468 kcal × 1.55 activity
Women (maintenance)
2017 kcal/day
BMR 1302 kcal × 1.55 activity
These figures use the Mifflin-St Jeor BMR equation and assume age 30 with moderate activity (exercise 3–5 days a week, activity factor 1.55). They are estimates only — your actual needs shift with age, sex, muscle mass, and how active you really are. To lose about 0.5 kg/week, subtract roughly 550 kcal/day from these numbers.
How BMI changes near 55 kg (at 170 cm)
| Weight | BMI | WHO category | Indian category |

| 55 kg (this page) | 19 | Normal weight | Normal weight |
| 60 kg | 20.8 | Normal weight | Normal weight |
| 65 kg | 22.5 | Normal weight | Normal weight |
At 170 cm, every 5 kg changes your BMI by about 1.8 points. Small, steady changes in weight move you gradually between BMI bands — there is no need for drastic swings.

Frequently Asked Questions
Is 55 kg a healthy weight at 170 cm?▾
At 55 kg and 170 cm your BMI is 19. On the standard WHO scale that is "Normal weight", and on the Asia-Pacific/India scale (ICMR) it is "Normal weight". A weight of 53.5–72 kg (WHO BMI 18.5–24.9), or the stricter 53–66 kg by the Indian cutoff, is considered healthy for this height. Your weight is in the healthy range. Maintain a balanced diet and regular exercise.
What is the ideal weight for 170 cm height?▾
For 170 cm, the healthy weight band is 53.5–72 kg using the WHO BMI range (18.5–24.9), and 53–66 kg using the Indian/Asia-Pacific range (18.5–22.9). Classic ideal-weight formulas (Hamwi, Devine, Robinson, Miller) average to about 66 kg for men and 61.4 kg for women at this height — a single "ideal" figure inside the same range.
Do I need to lose or gain weight at 55 kg and 170 cm?▾
At 55 kg you are already inside the healthy range of 53.5–72 kg for 170 cm, so the goal is maintenance rather than loss or gain.
How many calories a day maintain 55 kg at 170 cm?▾
Using the Mifflin-St Jeor equation and assuming age 30 with moderate activity (exercise 3–5 days a week, activity factor 1.55), an estimated maintenance intake at 55 kg / 170 cm is about 2275 kcal/day for men and 2017 kcal/day for women. These are estimates — your real needs vary with age, muscle mass, and how active you are.
Is BMI accurate for muscular or athletic builds?▾
BMI only compares weight to height — it does not distinguish muscle from fat. A muscular or athletic person can show a BMI of 19 in the "overweight" band while carrying very little body fat, and a sedentary person at the same BMI can carry much more. For lean, heavily trained bodies, waist circumference, waist-to-height ratio, or a body-fat measurement gives a truer picture than BMI alone.
Why are the Indian (Asian) BMI cutoffs lower than the WHO standard?▾
Indians and other South and East Asians tend to carry more body fat and abdominal (visceral) fat at the same BMI as Western populations, and face heart-disease and type-2-diabetes risk at lower weights. So the ICMR and the WHO Asia-Pacific guidelines lower the thresholds: normal is 18.5–22.9 (not 24.9), the overweight/at-risk band starts at 23, and obesity begins at 25 instead of 30. At BMI 19 this is why your Indian category ("Normal weight") can differ from the WHO category ("Normal weight").
What health category does BMI 19 fall into?▾
A BMI of 19 is "Normal weight" on the WHO scale and "Normal weight" on the Indian/Asia-Pacific scale. Your weight is in the healthy range. Maintain a balanced diet and regular exercise. BMI is a screening tool, not a diagnosis — use it alongside waist size, blood pressure, blood sugar, and your doctor's advice.
