What is Protein?
Protein is one of the three primary macronutrients, along with fats and carbohydrates. It is the building block of body tissues and serves as a vital component in several biological functions, such as hormone production, enzyme activity, and oxygen transportation. Protein is made up of amino acids, which are essential to maintaining the structure and function of organs and tissues.
There are 20 different amino acids in total, and while some can be synthesized by the body, there are nine essential amino acids that we must obtain from our diet. Complete protein sources, which contain all nine essential amino acids, include foods like eggs, fish, lean meats, soy products, and quinoa. By combining different plant-based protein sources, you can ensure your diet provides all the essential amino acids needed for a healthy body.
How Much Protein Do I Need?
The amount of protein you need varies based on factors such as your weight, age, goals, and activity level. The minimum recommendation for the average sedentary adult is around 0.36 grams per pound of body weight. However, if you engage in intense exercise or have physically demanding activities, your protein needs may increase.
Our Protein Intake Calculator tailors recommendations to your lifestyle and fitness goals, whether you want to build muscle, lose weight, or maintain your health.
Why Should You Track Your Protein Intake?
For those who are highly active, training in the gym, or aiming to build muscle, tracking your protein intake is crucial for achieving optimal results. Knowing your protein needs helps ensure you’re fueling your body effectively for recovery and growth.

How Does the Protein Calculator Work?
The calculator uses established formulas to determine your daily protein needs. First, it calculates your Basal Metabolic Rate (BMR) using the Harris-Benedict equation, which estimates the number of calories your body needs to sustain basic functions at rest.
Calculating Your BMR
BMR is determined by your gender, weight, height, and age. Once your BMR is calculated, it is multiplied by an activity multiplier to estimate your maintenance calories, which represent the total number of calories needed based on your activity level.
