If John's BMI is 32 and he decreases it by six units, will he be in the healthy range?

To evaluate whether John's reduced BMI of 26 places him in the healthy range, it's important to understand the BMI categories defined by the World Health Organization. A BMI of 18.5 to 24.9 is generally classified as healthy. Since John's starting BMI is 32, which falls into the obese category, reducing his BMI by six units to 26 moves him closer to the borderline of the overweight category (25 to 29.9) but does not encroach into what is considered a healthy range.

Therefore, while a decrease in BMI is typically a positive adjustment, simply achieving a BMI of 26 does not bring John into the healthy range according to standard classifications. Maintaining awareness of BMI limits is key in the discussion of weight and health, and understanding these categories helps clarify why the reduction alone doesn't guarantee healthiness.
