Question

For adults, obesity is defined as:

Answer 1

Answer:

The correct answer is C, Being at least 20% over one's ideal body weight.

Explanation:

Ideal body weight is generally seen by analyzing the Body Mass Index of a person. This BMI is the ratio of person's weight in kilograms to its height in feet and inches. There are ranges of BMI in which people are categorized according to the weight and height ratio. If a person's BMI is above 30, they are in the obese category.

But according to this question, 20% overweight means adults are towards obesity.  

Answer 2

Answer:

C. Being at least 20% over one's ideal body weight.

Explanation:

Although it's an approximate measure, because the body weight (also known as Body Mass Index - BMI) doesn't accurately measure the obesity, the ratio of body fat in your body is much more representative.

So, yes, generally, being about 20% (some say 25%) over your ideal body weight (BMI) means you can be considered being fat.

Answer A is incorrect, and so is the formula expressed in it.

Answer B is also incorrect, since you can easily weight 200 lbs and still have an ideal weight if you're tall enough.

Answer D cannot be, since A and B are incorrect.
