Advertisement: Researchers studied a group of people trying to lose weight and discovered that those in the group who lost the most weight got more calories from protein than from carbohydrates and ate their biggest meal early in the day. So anyone who follows our diet, which provides more calories from protein than from anything else and which requires that breakfast be the biggest meal of the day, is sure to lose weight.

A
eating foods that derive a majority of their calories from carbohydrates tends to make one feel fuller than does eating foods that derive a majority of their calories from protein
The diet described involved a majority of calories from protein rather than from carbs. Whether a different kind of diet helps people “feel fuller” has no clear impact on whether the ad’s diet will help people lose weight.
B
a few of the people in the group studied who lost significant amounts of weight got nearly all of their calories from carbohydrates and ate their biggest meal at night
We know the group who “lost the most weight” got more calories from protein than from carbs. That doesn’t exclude the possibility that some people with a different diet also lost a lot of weight. They just didn’t lose the most weight.
C
the people in the group studied who increased their activity levels lost more weight, on average, than those who did not, regardless of whether they got more calories from protein or from carbohydrates
(C) suggests that exercise is another factor in weight loss. The author never assumed otherwise. The ad is merely arguing that following the ad’s diet will cause weight loss. Whether exercise also leads to weight loss doesn’t affect whether the diet leads to weight loss.
D
some people in the group studied lost no weight yet got more calories from protein than from carbohydrates and ate their biggest meal early in the day
If this possibility is true, that means not everyone on the high-protein + big meal early diet lost weight. This shows why we can’t conclude that “anyone” on the ad’s diet will “be sure to” lose weight.
E
people who eat their biggest meal at night tend to snack more during the day and so tend to take in more total calories than do people who eat their biggest meal earlier in the day
(E) describes people on a different kind of diet that isn’t what the ad describes. What’s true about those people has no affect on what will happen to people following the ad’s diet.
