Question

The Olympic swimmer, Michael Phelps, required 10,000 calories during training. He needed 30% protein, 50% carbohydrates and 20% fat. How many calories did he need for each nutrient?

1 gram of carbs= 4 calories, 1 gram of protein=4 calories, 1 gram of fat= 9 calories.

Answer 1

750 grams of protein, 222.22 of fat, and 1,250 of carbs.

Explanation:

3,000 calories from protein, 2,000 from fat, and 5,000 from carbs.

3000 / 4 = 750 grams of protein.

2,000 / 9 = 222.22 grams of fat.

5,000 / 4 = 1,250 grams of carbs.
