By Jesús Narváez Tamés ·
A worked example above 30, in grade I obesity. What each grade means and why the first goal is not the normal range.

- Weight

- WHO category
- Obesity grade I
- Weight in the 18.5–24.9 range
- 56.7–76.3 kg
A hundred kilos at 1.75 m passes the 30 cut-off and lands in grade I obesity. The WHO uses three grades: I from 30 to 34.9, II from 35 to 39.9 and III from 40. The table below shows the normal weight range for this height.
Staring at that range is discouraging, and you do not need to. Losing 5 to 10 % of your weight already helps blood pressure, blood sugar and joints. A useful first goal is to leave the obesity grade, not to land in “normal”. If other conditions are involved, see a doctor.
How this was calculated
BMI = weight (kg) / height (m)². The cut-offs are the WHO ones. It does not separate muscle from fat.
