What is the energy requirement conversion for carbohydrates and proteins?

The correct energy requirement conversion for carbohydrates and proteins is indeed 4 kcal/g. This means that for every gram of carbohydrates or proteins consumed, the body can derive approximately 4 kilocalories of energy.

Carbohydrates and proteins both play crucial roles in nutrition and metabolism. Carbohydrates are the body's primary energy source, while proteins are essential for growth, repair, and maintenance of tissues. The energy yield of 4 kcal/g reflects the energy content that these macronutrients provide when metabolized.

In contrast, fats yield higher energy due to their chemical structure, which provides about 9 kcal/g. This is why, for dietary purposes, a balance of these macronutrients is important for energy management in the body. Understanding these conversions is fundamental for proper nutrition planning and dietary assessments.
