If a bagel contains 4 grams of fat, 30 grams of carbohydrates, and 8 grams of protein, how many calories does it provide?

To determine the total caloric content of the bagel, one must consider the caloric contribution of each macronutrient: fat, carbohydrates, and protein.

• Fat provides 9 calories per gram, so for 4 grams of fat, you calculate:

4 grams x 9 calories/gram = 36 calories.

• Carbohydrates offer 4 calories per gram, so for 30 grams of carbohydrates, the calculation is:

30 grams x 4 calories/gram = 120 calories.

• Protein also yields 4 calories per gram. Therefore, for 8 grams of protein, you find:

8 grams x 4 calories/gram = 32 calories.

Now, you add the calories from each macronutrient together:

36 calories (from fat) + 120 calories (from carbohydrates) + 32 calories (from protein) = 188 calories.

This total represents the overall caloric content of the bagel, confirming that it provides 188 kilocalories. Thus, the correct answer to the question is indeed 188 kilocalories.
