What is the BMI for 100 kg and 165 cm?
The BMI for 100 kg weight and 165 cm height is 36.7 — Obese on the standard WHO scale and Obese (Class II) on the Indian/Asia-Pacific scale. The healthy weight for 165 cm is 50.4–67.8 kg (WHO BMI 18.5–24.9), or the stricter 50–62 kg (Indian BMI 18.5–22.9) recommended by the ICMR.
BMI 36.7 on both classification scales
WHO / International
Asia-Pacific / India (ICMR)
A BMI of 36.7 is classified as Obese internationally and Obese (Class II) under the lower Indian cutoffs, which flag health risk from a BMI of 23 rather than 25.

32.2 kg over
to reach 67.8 kg
At 100 kg you are about 32.2 kg above the 67.8 kg upper limit of the healthy WHO range for 165 cm.
Reaching a healthy weight from 100 kg
To move from 100 kg into the healthy range you would aim to lose about 32.2 kg (down to 67.8 kg). A safe, sustainable pace is 0.5 kg per week, which needs roughly a 550 kcal/day calorie deficit.

~550 kcal
daily deficit
In practice that means eating roughly 2374 kcal/day (men) or 2116 kcal/day (women) from the maintenance estimates below, ideally combining a modest food reduction with more daily movement rather than dieting alone. Losing faster than about 1 kg/week is rarely advisable without medical supervision.
Estimated daily calories at 100 kg / 165 cm
Men (maintenance)
2924 kcal/day
BMR 1886 kcal × 1.55 activity
Women (maintenance)
2666 kcal/day
BMR 1720 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 100 kg (at 165 cm)
| Weight | BMI | WHO category | Indian category |
|---|---|---|---|
| 90 kg | 33.1 | Obese | Obese (Class II) |
| 95 kg | 34.9 | Obese | Obese (Class II) |
| 100 kg (this page) | 36.7 | Obese | Obese (Class II) |
| 105 kg | 38.6 | Obese | Obese (Class II) |
| 110 kg | 40.4 | Obese | Obese (Class II) |
At 165 cm, every 5 kg changes your BMI by about 1.9 points. Small, steady changes in weight move you gradually between BMI bands — there is no need for drastic swings.

Frequently Asked Questions
Is 100 kg a healthy weight at 165 cm?▾
At 100 kg and 165 cm your BMI is 36.7. On the standard WHO scale that is "Obese", and on the Asia-Pacific/India scale (ICMR) it is "Obese (Class II)". A weight of 50.4–67.8 kg (WHO BMI 18.5–24.9), or the stricter 50–62 kg by the Indian cutoff, is considered healthy for this height. Significant health risks. Medical consultation recommended alongside a diet and fitness program.
What is the ideal weight for 165 cm height?▾
For 165 cm, the healthy weight band is 50.4–67.8 kg using the WHO BMI range (18.5–24.9), and 50–62 kg using the Indian/Asia-Pacific range (18.5–22.9). Classic ideal-weight formulas (Hamwi, Devine, Robinson, Miller) average to about 61.9 kg for men and 57.6 kg for women at this height — a single "ideal" figure inside the same range.
How much weight do I need to lose to be normal at 165 cm?▾
To reach the healthy range (up to 67.8 kg for 165 cm), you would aim to lose about 32.2 kg. At a safe 0.5 kg/week that is roughly 65 weeks (about 15 months), supported by an approximate 500–550 kcal/day calorie deficit.
How many calories a day maintain 100 kg at 165 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 100 kg / 165 cm is about 2924 kcal/day for men and 2666 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 36.7 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 36.7 this is why your Indian category ("Obese (Class II)") can differ from the WHO category ("Obese").
What health category does BMI 36.7 fall into?▾
A BMI of 36.7 is "Obese" on the WHO scale and "Obese (Class II)" on the Indian/Asia-Pacific scale. Significant health risks. Medical consultation recommended alongside a diet and fitness program. BMI is a screening tool, not a diagnosis — use it alongside waist size, blood pressure, blood sugar, and your doctor's advice.
