On January 1, an overweight college student, 5'5" tall with a BMI of 28, sets a
long-term goal to achieve a normal body composition by summer. Which of
these is the best benchmark for him to set for himself?

The answer is: Lose 10 pounds in three months.

Explanation:

BMI is calculated with this formula: This mean that for a 1. 65 meter (5'5'')  tall student to obtain a BMI of 28, the weight must beweight = BMI x 1.65^2weight = 28 x 2.7225weight = 76.23 kilograms.Normal BMI range is 18  -  25To reach a BMI of 25, the student's weight must be'weight =  25 x 1.65^2weight  = 68 kilogramsTotal weight that the student need to lose = 76.23 kg -  68 kg = 8.23 kg     or       18.14 poundHealthy amount of weight to lose is around 1  pounds per week. So, the student need around  18 weeks to lose all the weight.Because of this, losing 10 pound in three months (12 weeks)  is a good benchmark since it provide realistic timing and expectation for the student.

Hope this helps ;)
