Logic Breakdown
Passage Summary: The author thinks a zero-calorie fat substitute is useless because it makes people so hungry that they end up eating more calories later anyway.
Conclusion: The fat substitute N5 is not useful for people trying to reduce their fat and calorie intake.
Reasoning: People who eat N5 feel hungrier and eat more later, which cancels out the calories they initially saved.
Analysis: The argument identifies two goals—reducing fat and reducing calories—but only addresses the failure to reduce calories. Even if a person eats more total calories later to satisfy their hunger, they might still be successful in reducing their total fat intake if those extra calories come from non-fat sources. The author's logic is flawed because it assumes that failing one goal (calories) automatically means failing the other (fat). Look for an answer that points out this gap between the two distinct objectives mentioned in the stimulus.

The argument’s conclusion is that N5 is of no use to people aiming to reduce fat and calories. E points out that total fat intake may still drop even if calories do not, revealing a significant unconsidered benefit and undercutting the “no use” conclusion.
