_______ have more than twice as many of calories as do proteins or carbohydrates.

Yes.

To determine the answer, we need to compare the calorie content of different nutrients.

First, let's consider proteins. Proteins contain approximately 4 calories per gram.

Next, carbohydrates also contain approximately 4 calories per gram.

Now, fats contain more than twice the amount of calories compared to proteins or carbohydrates. Fats contain approximately 9 calories per gram, making them the most calorie-dense nutrient.

Based on this information, the correct answer is D. Fats.
