LR Question 8 Explanation

QUESTION TEXT: Nutritionist: Many people claim that simple carbohydrates…

QUESTION TYPE: Most Strongly Supported

FACTS:

1. Many people claim that people on a low-fat diet should eat simple carbohydrates.
2. Yet we now know that eating lots of carbs produces insulin.
3. Insulin lets us make energy from sugars or starches.
4. If energy isn’t required then insulin produces fat instead.

ANALYSIS: This says that a low-fat diet can make you fat. Specifically, simple carbs can make you fat.

___________

1. This is tempting but actually a low fat diet produces energy. Lots of energy. So much that you don’t need it all and insulin produces fat as well.
2. We actually have no idea what the advantages of a low-fat diet are. The stimulus doesn’t say who should eat one.
3. Same as B. We don’t know who should limit fat or why. It’s more strongly supported that we should limit simple carbohydrates. 
4. CORRECT. It looks like simple carbohydrates cause weight gain. So don’t eat too many unless you want to gain weight. 
5. This says that if you don’t produce much insulin you’ll have a hard time losing weight by getting rid of carbohydrates. Maybe? All we know is that insulin can cause weight gain. There’s no reason to think that lack of insulin prevents weight loss.
