How to Determine Your Protein Needs

How to Determine Your Protein Needs

The protein requirements for individuals vary based on factors such as muscle mass, activity level, age, and fitness goals. While chicken and broccoli are commonly included in bodybuilding diets, determining the ideal daily protein intake is essential. The National Institutes of Health (NIH) recommends a protein intake of 0.8 grams per kilogram of body weight (or 0.36 grams per pound of body weight) as the Recommended Daily Allowance (RDA). However, it’s worth noting that a healthy diet can consist of protein ranging from 10% to 35% of total daily caloric intake.


If you’re looking for a convenient and hassle-free way to calculate your protein requirements, the MyFitnessPal app offers a simple solution. By entering your details, such as body mass and calorie goals, the app provides personalized targets tailored to your needs. Additionally, age can influence protein requirements, and a higher protein intake may be necessary to prevent muscle loss as we age.

While the National Institutes of Health (NIH) suggests that the Recommended Daily Allowance (RDA) adequately meets the protein needs of active individuals, other prominent researchers and nutrition professionals recommend a higher protein intake to cater to the demands of physical activity. Here’s a summary of the recommendations:

  • Healthy adults/sedentary individuals: 0.8g/kg
  • Pregnant women: 1.1g/kg
  • Lactating women: 1.3g/kg
  • Endurance athletes: 1.2–1.4g/kg
  • High-intensity interval training/Stop-and-go sports: 1.4–1.7g/kg
  • Strength athletes (to gain muscle mass): 1.6–1.7g/kg
  • Strength training (to maintain): 1.2–1.4g/kg
  • Weight loss, calorie-restricted diets: 1.4–1.5g/kg

To calculate your specific protein needs, convert your weight in pounds to kilograms by multiplying it by 0.454. Then, multiply your weight in kilograms by the recommended protein value in grams to determine your total daily protein requirement.

It’s important to keep in mind that consuming more than 2.0g/kg of protein has not shown any additional benefits, meaning that exceeding this amount does not necessarily lead to further advantages.


When evaluating the nutritional value of proteins, two crucial factors to consider are amino acid composition and digestibility. Animal proteins derived from sources such as meat, chicken, fish, eggs, and dairy are considered complete proteins as they contain all essential amino acids, unlike plant-based sources. Animal proteins are generally considered higher in quality due to their comprehensive amino acid profiles, including a higher concentration of leucine per gram of protein. Leucine is an amino acid that plays a vital role in triggering muscle protein synthesis and can also have implications for weight loss.


The timing of protein intake is a crucial aspect to consider as well. It is not recommended to consume your entire daily protein intake in a single meal. Instead, it is advisable to distribute your protein consumption evenly throughout the day, with meals containing around 20-30 grams of protein every 4-5 hours. This strategic approach to protein timing and portioning ensures that your body has a steady supply of essential amino acids, which are vital for achieving fitness and performance goals such as weight loss, muscle building, and exercise recovery. Furthermore, it helps to keep your body consistently fueled and satisfied throughout the day, as it aligns with the changes in blood sugar levels and hunger cues.

Protein content can vary among different food sources. Here are a few examples of high-protein foods that you can incorporate into your regular meal rotation:

  • 3 ounces of meat, fish, or poultry: 21 grams
  • 1 cup of cooked beans: 16 grams
  • 1 cup of dairy or soy milk: 8 grams
  • 1 egg: 6 grams

In maintaining your daily protein intake, it’s important to choose a variety of protein-rich food sources. By incorporating high-protein foods such as meat, fish, poultry, beans, dairy, and eggs into your balanced diet, you can ensure that your body receives the necessary protein it needs for optimal health and performance.
