Question

select the correct answer.

what is the bmi?

a tool to measure and evaluate individual weight
a tool to find ones ideal number of daily calories
a tool to measure the ratio of lean muscle to fat

Explanation:

Define Body Mass Index (BMI)

Body Mass Index (BMI) is a value derived from the mass (weight) and height of a person, used as a screening tool to identify whether an individual is underweight, normal weight, overweight, or obese.

Evaluate the options

• Option 1: "a tool to measure and evaluate individual weight" directly aligns with the definition of BMI as a screening tool for weight categories.
• Option 2: "a tool to find one's ideal number of daily calories" describes metabolic rate calculators or nutritional planning tools, not BMI.
• Option 3: "a tool to measure the ratio of lean muscle to fat" describes body composition analysis (like bioelectrical impedance or DEXA scans), whereas BMI only uses total weight and height without distinguishing muscle from fat.

Answer:

• a tool to measure and evaluate individual weight (Correct answer)
• a tool to find one's ideal number of daily calories
• a tool to measure the ratio of lean muscle to fat
