The passage argues that foods with little or no fat leave people feeling unsatisfied, so they are likely to eat more than they would of foods that have a substantial fat content. Although the evidence suggests that eating a low-fat diet is better than a no-fat diet (choice A), choice B is a more logical conclusion, especially because the focus in the passage is how much we eat. The health value of potato chips, which are only used as an example, is not discussed, so choice C is incorrect. Choice D is incorrect because the passage suggests that weight control is a matter of what kind of foods people eat, not the suppression of cravings. The passage does not state that fat-free foods should be banned from stores, so e is not a logical conclusion.
