If James's daily caloric needs are 2200 calories, how many calories does he get from protein with 5% of his intake?

To determine how many calories James gets from protein, you need to calculate 5% of his total daily caloric needs of 2200 calories. To do this, multiply 2200 by 0.05 (5% expressed as a decimal):

2200 calories x 0.05 = 110 calories.

This means that if protein constitutes 5% of his caloric intake, he consumes 110 calories from protein each day. Understanding the percentage calculation is crucial for evaluating macronutrient contributions to total caloric intake, as it allows one to break down the total caloric needs into specific macronutrient sources—protein, fats, and carbohydrates.
