Sixty adults were asked to keep a diary of their meals, including what they consumed, when, and in the company of how many people. It was found that at meals with which they drank alcoholic beverages, they consumed about 175 calories more from nonalcoholic sources than they did at meals with which they did not drink alcoholic beverages. Each of the following, if true, contributes to an explanation of the difference in caloric intake EXCEPT: ['At meals that included alcohol, relatively more of the total calories consumed came from carbohydrates and relatively fewer of them came from fats and proteins.', 'Diners spent a much longer time at meals served with alcohol than they did at those served without alcohol.', 'People eat more when there are more people present at the meal, and more people tended to be present at meals served with alcohol than at meals served without alcohol.', 'The meals that were most carefully prepared and most attractively served tended to be those at which alcoholic beverages were consumed.']
