The stimulus does not say anything about “maintaining energy.” The nutritionist is focused on how excess carbohydrates lead to the accumulation of more fat.

The stimulus says nothing about people who produce enough insulin. The Nutritionist is focused on people who were on low-fat diets and are considering switching to a high-carb diet

This is too strong to support. The Nutritionist does not suggest limiting the intake of high-fat foods for those who consume simple carbohydrates. It focuses on the effects of simple carbohydrates, not fats.

The stimulus supports the idea that those who want to avoid gaining fat should limit their intake of carbs because these can cause an overproduction of insulin, which leads to more fat.

This is far too specific and strong to support. The Nutritionist does not claim that only restricting carbs will/will not result in weight loss. It is only talking about consuming an excess of carbs
