How Much Protein Do You Really Need for Performance?

Key Points

  • DAILY PROTEIN REQUIREMENTS.  Daily Protein needs are not one-size-fits-all; they depend on factors like age, weight, and activity level. Different types of exercises, from sedentary to endurance, require varying protein intake levels. 
  • CALCULATING DAILY PROTEIN REQUIREMENT. You can estimate your daily Protein requirement by multiplying your weight in kilograms or pounds by the recommended protein intake range based on your exercise level or check out our Protein Calculator, which does it for you.  
  • TIMING MATTERS. Consuming Protein before and after exercise can support reaching daily requirements and supports muscle recovery and growth. Spreading Protein intake throughout the day helps maintain muscle health. 
  • QUALITY PROTEIN SOURCES. Not all Proteins are equal. High-quality sources like lean meats, fish, eggs, dairy, and some plant-based options provide essential Amino Acids and nutrients necessary for overall health. 
  • PROTEIN SUPPLEMENTS. Alongside food, Whey Protein is a great high quality option to supplement your diet to support daily Protein intakes. 

Supporting performance goals requires more than just hard work in the gym or on the field. It’s about supplying your body with the right nutrients, and one crucial aspect of this is Protein intake. This article will guide you through the importance of Protein and how your daily requirements can vary depending on your exercise routine. Let’s dive in and unlock the potential of Protein for your performance. 

Understanding the Building Blocks: What is Protein? 

Before we get into the nitty-gritty of daily Protein requirements, let’s start with the basics. Protein is one of the essential Macronutrients that make up the foundation of our bodies. It plays a vital role in processes such as building and repairing tissues, supporting immune function, and even acting as enzymes and hormones. 

The Daily Protein Needs: One Size Does Not Fit All 

Your daily Protein needs are not one-size-fits-all; they vary based on several factors, including your age, gender, weight, and activity level1. Let’s break down the Protein requirements for different types of exercises: 

  1. Sedentary Lifestyle: If you have a mostly sedentary lifestyle, with little or no exercise, your Protein requirements will generally be lower. Aim for around 0.8g of Protein per kilogram of body weight per day or 0.36 grams of Protein per pound of bodyweight per day. 
  2. Light to Moderate Exercise: For those engaging in light to moderate exercise, such as daily walks or casual workouts, you’ll want to target about 1-1.2 g of Protein per kilogram of body weight per day or 0.45 -0.54 grams of Protein per pound of bodyweight per day1. This level of Protein intake helps with muscle building and maintaining general health. 
  3. Strength Training and Resistance Exercise: If you’re hitting the gym for strength training or resistance exercises, you should increase your protein intake. Aim for between 1.6-2.2 g of protein per kilogram of body weight per day or 0.74 to 1.0 grams of Protein per pound of bodyweight per day2. Protein becomes crucial for muscle repair and growth in this scenario. 
  4. Endurance Athletes: Endurance athletes, such as marathon runners or long-distance cyclists, also have higher daily Protein requirements. Shoot for 1.6 g of protein per kilogram of body weight per day or 0.74 grams of Protein per pound of bodyweight per day. Protein helps in muscle recovery. 

Calculating Your Daily Protein Requirement

To calculate your daily protein requirement accurately, consider the following steps: 

  1. Determine your weight in kilograms (your weight in pounds divided by 2.2). 
  2. Identify your exercise intensity level (sedentary, light to moderate exercise, strength training, or endurance exercise). 
  3. Use the recommended protein intake range for your exercise level, as mentioned earlier in this article. 
  4. Multiply your weight in kilograms (pounds divided by 2.2) by the appropriate Protein intake range (e.g., if you’re engaging in strength training, multiply by your weight in kg by 1.6-2.2g. For example, an 80 kg individual may require 160g of protein daily (80 kg x 2 kg protein/ kg of bodyweight). 

The result will give you an estimate of your daily Protein requirement. To take the hassle out of having to calculate your requirements, check out our Protein Calculator.  

Protein Timing: When and How Much? 

Hitting your daily Protein intake is the most important factor when it comes to gaining the performance benefits of Protein. However, your muscle can typically only absorb approximately 20-40g of protein per sitting. Therefore, to maximize its benefits, consider eating 20-40 g of protein at these key moments: 

Pre-Exercise

Consuming some Protein before your workout can help provide your muscles with the necessary Amino Acids. A small Protein-rich snack, such as a Greek Yogurt topped with berries, or a Protein Shake, 30 minutes to an hour before exercise can be beneficial. 

Post-Exercise

Consuming Protein within a couple of hours post-workout is beneficial for muscle recovery, but the exact timing isn’t as critical as consistency in hitting your overall daily Protein requirements. 1, 3

However, consuming Protein at this time may be a good habit to ensure you are hitting your daily Protein requirements and providing the muscle with the Essential Amino Acids it needs.  

Throughout the Day 

To meet your daily Protein goals, spread your Protein intake, across your meals and snacks. As you are aiming to consume at least 20g of Protein with each meal and snack, protein shakes and protein bars can be an easy option to help you hit this Protein goal. This consistent supply of Protein helps with muscle maintenance and growth. 

The Quality Matters: Sources of Protein 

Not all Protein sources are created equal. Choose Protein sources that provide Essential Amino Acids and additional nutrients. Here are some excellent choices: lean Meats (Chicken, Turkey, Beef), Fish (Salmon, Tuna, Trout), Eggs, Dairy products, and Plant-Based options, such as, Tofu, Legumes, and Quinoa. 

Are plant-based Protein sources as effective as animal-based ones? 

Plant-based Protein sources can be just as effective as animal-based ones when combined strategically to ensure you get all Essential Amino Acids. Read more on this topic here.

Can you get all the Protein you need from food, or do you need supplements? 

While you can meet your Protein requirements through food, supplements can be convenient, especially for athletes with higher Protein needs. In this instance a Protein Shake, such as Gold Standard 100% Whey Protein is a tasty way to get high quality Protein into your diet, helping you hit your daily Protein targets. 

Is it Possible to Overconsume Protein? 

There is not enough evidence to indicate that Protein at high levels cause negative health effects in healthy adults.

Conclusion: Fuel Your Performance with the Right Protein 

In conclusion, Protein is a fundamental component of your diet, especially if you are dedicated to training and reaching your performance goals. Your daily Protein needs vary based on your exercise routine, so it’s essential to tailor your intake accordingly. Quality Protein sources should be a part of your daily nutrition to support muscle building* and overall health. Consulting a registered dietitian nutritionist can provide accurate guidance on calculating your Protein needs and ensuring your nutrition aligns with your performance goals. 

*When paired with regular resistance training.
