The correct Answer is:
To determine the energy content in Kcal/g of carbohydrates, proteins, and triglycerols (fats) and express it in the form of a ratio, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Energy Content of Each Nutrient**: - Carbohydrates provide approximately **4 Kcal/g**. - Proteins also provide approximately **4 Kcal/g**. - Triglycerols (fats) provide approximately **9 Kcal/g**. 2. **Establish the Ratio**: - Based on the energy content identified: - Carbohydrates = 4 Kcal/g - Proteins = 4 Kcal/g - Triglycerols = 9 Kcal/g - Now, we can express these values in a ratio format: - Carbohydrates : Proteins : Triglycerols = 4 : 4 : 9 3. **Simplify the Ratio**: - To simplify the ratio, we can express it in a more manageable form. Since 4 and 4 are the same, we can represent them as 1: - 4 : 4 : 9 simplifies to 1 : 1 : 2.25. - However, for practical purposes, we can round 2.25 to 2 for a simpler ratio, which gives us: - 1 : 1 : 2. 4. **Final Ratio**: - Therefore, the final ratio of the energy content in Kcal/g of carbohydrates : proteins : triglycerols is approximately **1 : 1 : 2**. ### Conclusion: The energy content in Kcal/g of carbohydrates, proteins, and triglycerols respectively is approximately in the ratio of **1 : 1 : 2**.

One of the first diets to limit the intake of carbohydrates was prescribed by Dr. William Harvey in 1862. The diet consisted of three meals a day containing equal amounts of protein per meal. IF protein contains 4 dietary calories per gram, and the diet consisted of 672 dietary calories of protein per meal, how much protein, to the nearest ounce, was in each meal? (1 ounce is approximately 28 grams.)
