What is considered a healthy body mass index (BMI)?

• A. A BMI under 18.5
• B. A BMI between 18.5 and 24.9
• C. A BMI of 25 or higher
• D. A BMI higher than 30

Answer: (B)

A healthy body mass index (BMI) is recognized as a value between 18.5 and 24.9. This range is associated with optimal health and a reduced risk of developing weight-related health conditions. It reflects a balance between weight and height that typically supports healthy bodily functions and overall well-being.

A BMI under 18.5 is categorized as underweight, which can be associated with various health risks, including nutritional deficiencies and weakened immune function. Conversely, a BMI of 25 or higher indicates overweight or obesity, where higher body fat levels can lead to health complications such as diabetes, heart disease, and hypertension. A BMI over 30 is classified as obesity, which presents significant health risks.

Thus, the range of 18.5 to 24.9 is considered ideal, as it signifies a healthier relationship with weight that promotes longevity and quality of life.
