What is the BMI for 100 kg and 155 cm?
The BMI for 100 kg weight and 155 cm height is 41.6 — Obese on the standard WHO scale and Obese (Class II) on the Indian/Asia-Pacific scale. The healthy weight for 155 cm is 44.4–59.8 kg (WHO BMI 18.5–24.9), or the stricter 44–55 kg (Indian BMI 18.5–22.9) recommended by the ICMR.
BMI 41.6 on both classification scales
WHO / International
Asia-Pacific / India (ICMR)
A BMI of 41.6 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.

40.2 kg over
to reach 59.8 kg
At 100 kg you are about 40.2 kg above the 59.8 kg upper limit of the healthy WHO range for 155 cm.
Reaching a healthy weight from 100 kg
To move from 100 kg into the healthy range you would aim to lose about 40.2 kg (down to 59.8 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 2277 kcal/day (men) or 2020 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 / 155 cm
Men (maintenance)
2827 kcal/day
BMR 1824 kcal × 1.55 activity
Women (maintenance)
2570 kcal/day
BMR 1658 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 155 cm)
| Weight | BMI | WHO category | Indian category |
|---|---|---|---|
| 90 kg | 37.5 | Obese | Obese (Class II) |
| 95 kg | 39.5 | Obese | Obese (Class II) |
| 100 kg (this page) | 41.6 | Obese | Obese (Class II) |
| 105 kg | 43.7 | Obese | Obese (Class II) |
| 110 kg | 45.8 | Obese | Obese (Class II) |
At 155 cm, every 5 kg changes your BMI by about 2.1 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 155 cm?▾
At 100 kg and 155 cm your BMI is 41.6. On the standard WHO scale that is "Obese", and on the Asia-Pacific/India scale (ICMR) it is "Obese (Class II)". A weight of 44.4–59.8 kg (WHO BMI 18.5–24.9), or the stricter 44–55 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 155 cm height?▾
For 155 cm, the healthy weight band is 44.4–59.8 kg using the WHO BMI range (18.5–24.9), and 44–55 kg using the Indian/Asia-Pacific range (18.5–22.9). Classic ideal-weight formulas (Hamwi, Devine, Robinson, Miller) average to about 53.7 kg for men and 50.2 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 155 cm?▾
To reach the healthy range (up to 59.8 kg for 155 cm), you would aim to lose about 40.2 kg. At a safe 0.5 kg/week that is roughly 81 weeks (about 19 months), supported by an approximate 500–550 kcal/day calorie deficit.
How many calories a day maintain 100 kg at 155 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 / 155 cm is about 2827 kcal/day for men and 2570 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 41.6 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 41.6 this is why your Indian category ("Obese (Class II)") can differ from the WHO category ("Obese").
What health category does BMI 41.6 fall into?▾
A BMI of 41.6 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.
