问题 What is the passage mainly about? [br]  
A new study suggests that the way to weight loss may be clear. A couple of glasses of water before meals helped dieters lose about 5 pounds more than those who did not drink water. While drinking water before a meal may fill a person up, the contents of their meal count as well. Should a person be eating a low-fat diet or a low-carb diet? Or does it matter at all?
    Recent research suggests that one diet isn’t any better than the other. What helps a person see a diet through? It could be body type.
    A study published in the Journal of the American Medical Association really drills down into the low-fat /low-carb debate. As reported by Time magazine, researchers found that body shape is the key to which diet a person will be able to stick with. Apples are people who carry most of their weight above the belt, while pears carry their weight around their hips, Apple types were more likely to be high-insulin secretors who respond more strongly to carbohydrates or sugars in their bodies. They lost the most weight on a low-carb diet. Pears were low-insulin secretors who lost the same amount of weight on both diets.
    All of these studies again come down to choosing the diet that helps you eat less. The body-type diet does make some sense as men are more likely to be apple types, with larger bellies, and tend to do well on higher-protein diets, while women, who tend to carry weight around their hips, find themselves drawn to the low-fat diets.

选项 A、They could lose the most weight on pears.
B、They could lose the most weight on a low-fat diet.
C、They could lose the most weight on a low-carb diet.
D、They could lose the same amount of weight on both diets.
