Q1
A meal contains 15 grams of fat, 30 grams of carbohydrates, and 10 grams of protein. How many total calories does this meal provide? (Fat = 9 cal/g, Carbohydrates = 4 cal/g, Protein = 4 cal/g) (2021)
Q: A meal contains 15 grams of fat, 30 grams of carbohydrates, and 10 grams of protein. How many total calories does this meal provide? (Fat = 9 cal/g, Carbohydrates = 4 cal/g, Protein = 4 cal/g) (2021)
Step 1: Identify the amount of fat, carbohydrates, and protein in the meal. We have 15 grams of fat, 30 grams of carbohydrates, and 10 grams of protein.
Step 2: Know the calorie values for each macronutrient: Fat has 9 calories per gram, carbohydrates have 4 calories per gram, and protein has 4 calories per gram.
Step 3: Calculate the calories from fat by multiplying the grams of fat by the calories per gram: 15 grams of fat * 9 calories/gram = 135 calories.
Step 4: Calculate the calories from carbohydrates by multiplying the grams of carbohydrates by the calories per gram: 30 grams of carbohydrates * 4 calories/gram = 120 calories.
Step 5: Calculate the calories from protein by multiplying the grams of protein by the calories per gram: 10 grams of protein * 4 calories/gram = 40 calories.
Step 6: Add all the calories together to find the total calories in the meal: 135 calories (from fat) + 120 calories (from carbohydrates) + 40 calories (from protein) = 295 calories.
