Verified step by step guidance

Step 1: Begin by understanding the concept of macronutrients. Macronutrients are nutrients required in large amounts by the body to provide energy and support bodily functions. The three essential energy-yielding macronutrients are carbohydrates, proteins, and fats (lipids).

Step 2: Recognize that vitamins are not considered macronutrients. Vitamins are classified as micronutrients because they are required in smaller amounts and do not directly yield energy. Instead, they play a role in facilitating biochemical reactions in the body.

Step 3: Compare the options provided in the question. Fats (lipids), proteins, and carbohydrates are all energy-yielding macronutrients, while vitamins are not.

Step 4: Identify the correct answer based on the definition and classification of macronutrients. Vitamins do not belong to the category of energy-yielding macronutrients.

Step 5: Conclude that the correct answer to the question is 'Vitamins,' as they are not considered one of the essential energy-yielding macronutrients.
