Protein is an essential macronutrient that is crucial for optimal health. It is required for building and repairing tissues, producing hormones and enzymes, and maintaining a healthy immune system. However, the amount of protein an individual needs varies based on several factors, including age, activity level, and overall health. This article will help you understand how much protein you need and how to complete your daily protein intake.
What is Protein and why do I need it?
Protein is an essential macronutrient that plays many different roles in the body, including:
- Building and repairing tissues: Proteins are the main building blocks of tissues such as muscles, bones, skin, and organs. When tissues are damaged, the body uses proteins to repair and rebuild them.
- Enzymes and hormones: Many enzymes and hormones in the body are made of proteins. Enzymes help to speed up chemical reactions in the body, while hormones act as messengers, carrying signals between cells and organs.
- Immune function: Proteins are important for immune function, helping the body to fight off infections and disease.
- Transport and storage: Proteins are involved in transporting molecules around the body, such as oxygen in the blood. They can also act as storage molecules, storing nutrients such as iron in the liver.
- Energy: Although carbohydrates and fats are the body’s main sources of energy, proteins can also be broken down and used for energy in times of need.
Given its importance, you need to make sure you include adequate amounts of protein in your diet to support these functions and maintain good health.
Recommended Daily Allowance (RDA) for Protein
The National Institutes of Health (NIH) recommends the following RDA guidelines for protein intake:
- For sedentary adults, the RDA for protein is 0.8 to 1.2 grams per kilogram of body weight. This means that an adult who weighs 70 kilograms needs 56 to 84 grams of protein per day.
- For physically active adults who do strength training, the RDA is higher, at 1.3 to 1.8 grams per kilogram of body weight.
- Healthy adults who consume protein over the long term and athletes with experience can consume up to 2 grams per kilogram of body weight.
- Endurance athletes need around 1.3 grams per kilogram of body weight.
It is important to note that there is an upper limit to the amount of protein that can be safely consumed, which is 3.5 grams per kilogram of body weight for well-adapted individuals. Consuming excessive amounts of protein can cause kidney damage and increase the risk of dehydration.
If I am overweight, how much protein do I need?
For those with a high body weight, it is important to calculate the RDA for protein based on their lean body mass instead of their total body weight. This is because individuals with a high body weight may have a higher proportion of body fat that does not require protein for maintenance and growth.
Lean body mass refers to the amount of muscle, bones, and organs in the body that require protein for maintenance and growth. By calculating protein requirements based on lean body mass, individuals can ensure that they are getting enough protein to support the needs of their lean tissue.
To calculate your lean body mass, you can use a body composition scale or have a health professional perform a skinfold measurement or bioelectrical impedance analysis.
How Much Protein Do I Need To Gain Muscle?
To support muscle growth, it’s recommended to consume 1.6 to 2.2 grams of protein per kilogram of body weight per day. For example, an individual who weighs 70 kilograms would need to consume 112 to 154 grams of protein per day.
It’s also important to consume enough calories to support muscle growth. Consuming a calorie surplus, or more calories than you burn, can help provide the energy and nutrients needed for muscle growth.
In addition to consuming enough protein and calories, engaging in regular strength training exercises can help support muscle growth. Resistance Training can help stimulate muscle growth and help optimise the benefits of protein consumption.
How Much Protein Do I Need To Lose Weight?
Protein can be helpful for weight loss because it can help increase satiety and reduce appetite. Research suggests that consuming 25 to 30 grams of protein per meal can help promote feelings of fullness and lead to a reduction in overall calorie intake.
To determine your daily protein needs for weight loss, you can use the same RDA guidelines recommended by the National Institutes of Health (NIH). For sedentary adults, the RDA for protein is 0.8 to 1.2 grams per kilogram of body weight. For physically active adults or those doing strength training, the RDA is higher, at 1.3 to 1.8 grams per kilogram of body weight.
Research suggests that consuming 1.2 to 1.6 grams of protein per kilogram of body weight can help support weight loss. It’s important to note that while protein can be helpful for weight loss, it’s not a magic solution. To promote weight loss, you need to create a calorie deficit, which means consuming fewer calories than you burn. It’s still important to maintain a balanced diet and engage in regular physical activity to support overall health and weight loss goals.

Do I Need Protein Immediately After A Workout?
Consuming protein immediately after a workout can help support muscle recovery and growth. During a workout, muscle tissues break down, and consuming protein can help repair and rebuild these tissues.
Research suggests that consuming 20 to 30 grams of protein immediately after a workout can help support muscle recovery and growth. Consuming protein with carbohydrates can also help replenish glycogen stores in the muscles, which can be depleted during exercise.
However, it’s important to note that the timing of protein consumption isn’t as critical as previously believed. As long as an individual consumes enough protein throughout the day to meet their daily needs, the timing of protein intake may not have a significant impact on muscle growth and recovery.
Therefore, while consuming protein immediately after a workout can be beneficial, it’s not absolutely necessary. As long as an individual meets their daily protein requirements, they should be able to support muscle recovery and growth regardless of when they consume protein.
How can I complete my daily protein requirement?
Meeting daily protein needs can be challenging, especially for individuals following a vegetarian or vegan diet. However, there are several ways to help complete daily protein intake:
- Incorporate protein-rich foods into meals and snacks, such as lean meats, poultry, fish, eggs, dairy, legumes, nuts, and seeds.
- Consider using protein supplements, such as whey protein, casein protein, or plant-based protein powders.
- Plan meals and snacks in advance to ensure that protein-rich options are included.
- Aim to include protein in every meal and snack to help meet daily protein needs.
- Consider speaking with a registered dietitian to help develop a personalised meal plan that meets daily protein needs.

Some parting thoughts on protein
Protein is an essential macronutrient that plays a crucial role in the body, from building and repairing tissues to producing hormones and enzymes. Daily protein needs vary based on several factors, including age, activity level, and overall health. Meeting daily protein needs can be challenging, but incorporating protein-rich foods, using protein supplements, and planning meals in advance can help support optimal health and wellness goals.
