Question: how to calculate how much protein you need in a day?
Answer: To determine your protein needs in grams (g), first, calculate your weight in kilograms (kg) by dividing your weight in pounds by 2.2. Next, decide how many grams of protein per kilogram of body weight is appropriate for you. Use the low end of the range if you are in good health and are sedentary: 0.8g per kg.
