I don't think so as it directly attacks the highlighted part below...
SajjadAhmad
(B) states that Increased exercise will result in more desire to consume food and result in less weight loss..
Thus, (B) is correct in my opinion...

A, C, D - irrelevant.
Between B and E
E - author does not advert to all the people, but to those who want to lose weight
B attacks the conclusion and weakens the argument

Official Explanation
One of the most common patterns to look for with this type of question is the “surprise result,” that is, an unanticipated factor that defeats the expected outcome.
(B) fits this pattern: you’ll be so hungry from the workout that you’ll eat more. (Remember that you are told to accept the soundness of each of the answer choices.) The other choices just don’t have the same logical “zip.”
Anyway, (A) seems to strengthen the argument: it’s okay to do what the ad suggests.
And (C) doesn’t focus on the logic of the ad—even though it probably helps to explain why the ad might be effective.
(D) and (E) are wrong because they address issues that are not really on the table, so to speak; the ad is not addressing those who are already happy nor those who are overly thin.
The correct answer is (B).

The correct answer is (B).
You might be thinking that increased hunger after exercise shows the exercise is "working." But let's trace through what actually happens.
The Weight Loss Rule:
Weight loss occurs when: Calories consumed < Calories burned
The Advertisement's Logic:
• Skip lunch = Save ~500 calories
• Exercise instead = Burn ~200 calories
• Total benefit = 700 calorie deficit → Weight loss!
What Option B Does:
Option B says exercise → increased appetite → people eat more later
Here's the mechanism:
• Skip lunch = Save 500 calories ✓
• Exercise = Burn 200 calories ✓
• BUT increased appetite → eat 800+ calories at dinner
• Net result = GAIN calories overall → No weight loss!
Simple Example:
Imagine you skip a $10 lunch to save money, but the hunger makes you so ravenous that you spend $20 on dinner instead. Did you save money? No! You actually spent $10 more.
Therefore: Option B weakens the argument by showing the program backfires - people end up consuming more calories overall, not fewer.
The advertisement assumes: Skip lunch → eat less overall
Option B reveals: Skip lunch + exercise → eat MORE overall
This is why B is a classic weakener - it attacks the effectiveness of the proposed solution!
