Protein is a key nutrient for gaining muscle strength and size, losing fat, and smashing hunger. Use this calculator to find out how much protein you need to transform your body or maintain your size.
Protein is essential for life. It provides the building blocks for your body’s tissues, organs, hormones, and enzymes. This macronutrient is crucial for building and maintaining muscle mass. It also increases satiety, which is why it’s so important to get enough protein when you’re limiting your calories to meet a fat-loss goal.
The amount of protein you need depends on your weight, goals, and lifestyle. The daily minimum recommended by the National Institutes of Health is 0.36 grams per pound for a sedentary person. However, if you do intense workouts or have a physically demanding job, you’ll need more. While the average healthy diet provides enough protein for most people, it may benefit you to bump up your intake if you exercise to build muscle or lose fat, either from dietary protein or supplements.
The protein calculator on this page takes your body-composition goals and activity level into account to estimate your protein needs. Everyone is different, though, so experiment to find the right level of protein for your body. Start with the number given by the calculator, see how that makes you feel, and try adjusting your protein level up or down to see what amount makes you feel good and perform well.
