Can someone help explain these directions??

For the energy-yielding nutrients, please convert the amount (grams) consumed to calories.  This can be done by multiplying the amount of that nutrient consumed by the respective number of calories it provides (protein and carbohydrate 4 cal/gram; fat 9 cal/gram).  Divide that value from the total amount of energy (calories) consumed and multiply by 100 to determine the percent of energy contributed by that nutrient.

Certainly! Here's a step-by-step explanation of how to calculate the percent of energy contributed by each energy-yielding nutrient:

1. Identify the amount of each nutrient consumed in grams.
- Let's say you have the following amounts: protein = 50g, carbohydrate = 100g, and fat = 30g.

2. Multiply the amount of each nutrient consumed by the respective number of calories it provides.
- Protein and carbohydrate provide 4 calories per gram, and fat provides 9 calories per gram.
- Therefore, multiply the amount of protein by 4, carbohydrate by 4, and fat by 9:
- Protein: 50g x 4 cal/g = 200 calories
- Carbohydrate: 100g x 4 cal/g = 400 calories
- Fat: 30g x 9 cal/g = 270 calories

3. Calculate the total amount of energy consumed.
- Add up the calories obtained from each nutrient:
- Total energy = 200 calories (protein) + 400 calories (carbohydrate) + 270 calories (fat) = 870 calories

4. Determine the percent of energy contributed by each nutrient.
- For each nutrient, divide the calories obtained from that nutrient by the total energy consumed, and then multiply by 100 to get the percentage.
- Let's calculate the percentages for each nutrient:
- Protein: (200 calories / 870 calories) x 100 = 22.99% (rounded to 23%)
- Carbohydrate: (400 calories / 870 calories) x 100 = 45.98% (rounded to 46%)
- Fat: (270 calories / 870 calories) x 100 = 31.03% (rounded to 31%)

So, according to the given nutrient amounts, 23% of the energy consumed is from protein, 46% from carbohydrate, and 31% from fat.
