How to Figure Out How Many Calories Come From Protein

To maintain a healthy diet, it is important to have a balance of carbohydrates, protein and fats. This can seem very complicated to determine particularly because nutrition labels on food can often be misleading. If you are concerned with how many calories you are getting from protein, which is an essential building block of muscles, this can be calculated quite easily using only a few pieces of information and some basic math. First, it is important to know that 1 gram of protein is equal to 4 calories.

Instructions

• 1

  Pick up a package of the food you are interested in. Look at the nutrition label provided and note the number of grams of protein per serving.

• 2

  Determine the number of servings you will be eating. Most people eat more than one serving so this is important to get an accurate value of how much protein you're consuming.

• 3

  Multiply the number of grams of protein by the number of servings you will be eating to get the total number of grams of protein for your meal.

• 4

  Calculate the number of calories from protein. Now that you know the number of grams of protein you'll be eating, multiply this number by 4, which is the amount of calories per gram of protein. This will be the number of calories you are getting from protein alone.
