Nuts are high in calories. All else being equal, the more calories one consumes, the more likely one is to become overweight. However, studies have found that people who eat nuts regularly are actually less likely to be overweight than people who never eat nuts. Which one of the following, if true, would most help to resolve the apparent discrepancy described above? ['If people who avoid a certain kind of food are more likely to be overweight than people who consume that food regularly, then that food should not be avoided for weight loss purposes .', 'The likelihood of becoming overweight depends not only on how many calories one consumes but also on how rapidly one burns those calories through physical activity.', 'On average, people who never eat nuts consume the same total calories per day as people who regularly eat nuts.', 'Most people who regularly eat nuts eat correspondingly less of foods whose taste, unlike that of nuts, stimulates a hunger response.']
