Research conducted by the National Institutes of Health (NIH) has established that a diet high in fiber, whole grains, and vegetables and low in hydrogenated or saturated fats and processed carbohydrates can help seriously overweight people lose weight quickly. Studies have also found that an epidemic of obesity is now the number one health crisis facing American high school students. Therefore, if American high schools offered as a lunch option specially prepared meals that adhere to the diet outlined by the NIH, the obesity rates of high school students would decrease significantly.

Which of the following, if true, most seriously weakens the argument above?

We have to look for an option which makes clear that a special high-fiber lunch at does not necessarily effectively eliminate the obesity problem in students.


(A) Students who consume a diet high in fiber, whole grains, and vegetables and low in processed carbohydrates are slightly more likely to fall asleep during afternoon classes than those who consume a diet high in lean proteins, such as fish and chicken. -- There is no comparative analysis of lean protein in the passage. Out of scope.

(B) Obese and overweight high school students usually have obese and overweight parents. -- Genetic elements are not discussed here. Also, it doesn't mean that both parents and students can't beat obesity together.

(C) Students who eat a lunch that adheres to the diet outlined by the NIH at least once a week are more likely to consume healthier foods at home. -- Strengthener. If the school lunch motivates the students to eat healthier, all the more good.

(D) Obese and overweight high school students are the least likely to choose a lunch option that adheres to the diet outlined by the NIH. -- CORRECT, this says that you can bring the healthy food to the table, but you can't make them eat it

(E) Many weight loss programs emphasize the importance of exercise in addition to a healthy, balanced diet. -- irrelevant and outside the scope of the passage.

So, Answer is D

Conclusion: if American high schools offered as a lunch option (diet outlined by NIH ) the obesity rates students would decrease significantly

(D) Obese and overweight high school students are the least likely to choose a lunch option that adheres to the diet outlined by the NIH. CORRECT: if targeted students don't choose NEW lunch option then obesity rate either remains the same or will increase
