which meal has the most calories?

a meal with 10 grams of protein

a meal with 5 grams of fat, 1 gram of carbohydrates

a meal with 10 grams of carbohydrates and 5 grams of fat

a meal with 1 gram of carbohydrates, 1 gram of protein, and 1 gram of fat

Explanation:

Step1: Recall calorie values per gram

Protein: $4$ cal/g, Carbohydrates: $4$ cal/g, Fat: $9$ cal/g.

Step2: Calculate calories for Option A

$10\ \text{g protein} \times 4\ \text{cal/g} = 40\ \text{cal}$.

Step3: Calculate calories for Option B

$5\ \text{g fat} \times 9\ \text{cal/g} + 1\ \text{g carb} \times 4\ \text{cal/g} = 45 + 4 = 49\ \text{cal}$.

Step4: Calculate calories for Option C

$10\ \text{g carb} \times 4\ \text{cal/g} + 5\ \text{g fat} \times 9\ \text{cal/g} = 40 + 45 = 85\ \text{cal}$.

Step5: Calculate calories for Option D

$1\ \text{g carb} \times 4 + 1\ \text{g protein} \times 4 + 1\ \text{g fat} \times 9 = 4 + 4 + 9 = 17\ \text{cal}$.

Step6: Compare calories

$85 > 49 > 40 > 17$, so Option C has the most calories.

Answer:

A meal with 10 grams of carbohydrates and 5 grams of fat
