How many calories are found in a brownie containing 15 grams of carbohydrates, 2 grams of protein, and 13 grams of fat?

To calculate the total caloric content of the brownie, you need to consider the calorie contributions from carbohydrates, proteins, and fats, as each macronutrient has a specific caloric value per gram.

• Carbohydrates provide 4 calories per gram. Therefore, for 15 grams of carbohydrates, the calculation is:

15 grams x 4 calories/gram = 60 calories.

• Proteins also provide 4 calories per gram. For 2 grams of protein, the calculation is:

2 grams x 4 calories/gram = 8 calories.

• Fats provide a higher caloric value of 9 calories per gram. For 13 grams of fat, the calculation is:

13 grams x 9 calories/gram = 117 calories.

Now, summing these amounts gives the total caloric content:

60 calories (from carbohydrates) + 8 calories (from protein) + 117 calories (from fat) = 185 calories.

This means that the brownie contains a total of 185 calories, supporting the choice. Understanding how these macronutrients contribute calorically is essential for estimating the energy content of various foods accurately. This is a fundamental aspect of nutrition that helps in meal planning
