Calculate Your Protein Intake: How Many Grams of Protein Do You Need?

If you eat a diet with 2,000 kilocalories and 45 percent of those calories come from protein, about how many grams of protein did you eat?100128200225

225

To answer this question, we can use the following equation:

Calories from protein = Total calories in diet x percentage of calories from protein / 100

Let’s plug in the values given in the question:

Calories from protein = 2,000 x 45 / 100 = 900 kilocalories

We know that 1 gram of protein provides 4 kilocalories of energy. Therefore, we can calculate the amount of protein in grams consumed as follows:

Protein in grams = Calories from protein / 4

Protein in grams = 900 kilocalories / 4 = 225 grams

So, if you eat a diet with 2,000 kilocalories and 45 percent of those calories come from protein, you would have consumed 225 grams of protein.
