Protein Intake Calculator

By definition, every essential nutrient is necessary for the proper functioning of the body. However, the focus for muscle strength and growth is always on protein intake.

Protein builds muscle, improves training, and accelerates recovery. The right amount is crucial for fitness and muscle growth, as well as for optimally supplying the body with protein during the recovery phase after training.

This article explains how much you should consume daily and when the best time to do so is. A handy calculator and tips for a healthy diet will help you consume the right amount of nutrients according to your activity level and achieve your goals.

What are proteins?

Proteins, along with carbohydrates and fats, are among the three macronutrients that are essential for healthy bodily function; they are the building blocks of the body.

Proteins consist of 20 amino acids, organic molecules. The body can produce some of these itself, while others, the so-called essential amino acids, must be obtained through food. There are nine essential amino acids.

Proteins perform specific functions in the body. Adequate protein levels ensure the correct structure of organs and tissues. Therefore, protein intake should be increased during growth and development. Proteins are also an essential component of cell function.

Proteins can also be categorized according to their function. Some act as messenger substances, transmitting signals that support various bodily functions. Other proteins are structural proteins and build cells.

How do I calculate my protein requirements?Empty heading

As with other nutrients, the amount of protein you need depends on various factors, including your energy requirements, whether you are growing or developing, and how much exercise you do.

The correct amount can be calculated in various ways based on age, body weight, or calorie intake. The recommended range is 10–35% of daily food intake.

Here you will find recommendations for different protein amounts depending on activity level.

Muscle building or maintenance (minimum)

The recommended daily allowance (RDA) is 0.8 g of protein per kg (or 0.36 g per lb) of body weight. This is the minimum to prevent deficiency in adults with a sedentary lifestyle. For active individuals or those wishing to maintain muscle mass, a more functional guideline of 0.8 g per lb of body weight is appropriate.

Muscle building (Recommended)

To build muscle You need to consume more protein than the recommended daily allowance. A recommended amount is 1 gram per pound of body weight.

Maximize growth and performance (High)

For very active people or those aiming for maximum growth and muscle building, the daily protein intake should be 1.2 g per pound of body weight.

Does it matter what type of protein you eat?

You can include many different protein sources and combinations in your diet to meet your needs.

Many people meet their protein needs through meat and dairy products. Plant-based alternatives exist for vegetarians and vegans. Although these generally contain less protein, they can be combined to meet the desired protein requirements.

The ideal combination is a mix of different protein sources, which also contributes to a balanced diet.

For nutritional purposes, proteins are divided into complete and incomplete proteins.

Complete proteins

A complete protein is a protein source that contains sufficient amounts of all nine essential amino acids.The nine essential amino acids are:

• Phenylalanine

• Histidine

• Isoleucine

• Leucin

• Lysine

• Methionine

• Threonine

• Tryptophan

• Valin

Here are some common animal sources of the nine essential amino acids:

• Lean beef

• chicken breast

• turkey breast

• Fish

• tuna

• shrimp

• eggs

• Milk

• Greek yogurt

• cottage cheese

Plant-based sources of essential amino acids include:

• Soy products such as tempeh, tofu and edamame beans

• Quinoa

• beans

• rice

• Buckwheat

• Hummus and pita

• Hemp and chia seeds

• Spirulina

Incomplete proteins

Incomplete proteins are protein sources that do not contain all nine essential amino acids. These sources are less effective than foods with complete proteins, but can still be valuable in the right combination.

Many healthy, protein-rich foods contain incomplete proteins, and many food sources that contain complete proteins, such as fatty red meat, are unhealthy.

It is possible to combine various foods containing incomplete protein, such as legumes and grains, to meet the recommended daily intake for your needs.

Here is a list of incomplete proteins; these are the most common sources for people who want to avoid meat, dairy products, and fish.

• lenses

• Ezekiel Bread

• peanuts

• pumpkin seeds

• Chia seeds

• Oats

• almonds

• Brussels sprouts

• broccoli

• Green peas

• Mushrooms

• grapefruit

• Avocados

Does the timing of protein intake play a role?

The benefits of protein consumption are undeniable, but does it make a difference when you consume this essential nutrient throughout the day?

It is generally accepted that animal protein is beneficial after training, especially after strength training or weightlifting, as it provides the essential amino acids for muscle growth. But let's look at the scientific findings:

A study in Medicine & Science in Sports & Exercise investigated various variables for sustainable muscle growth.

Forty physically active individuals, men and women, were asked to consume animal proteins and vegan meals at different times so that researchers could assess whether there was a difference in the body's protein synthesis after strength training.

The study found hardly any differences in the body's protein synthesis, regardless of whether protein intake was spread throughout the day or consumed in larger quantities with an evening meal. The type of protein consumed also had only a minor effect.

Further investigations within this study revealed another interesting result: that a vegan diet as a protein source can successfully build new muscle mass, which challenges some traditional views.

However, with vegan protein sources, it is crucial that the protein is balanced or "combined", for example by combining grains and legumes to complement the amino acid profile.

When it comes to the timing of protein intake, despite the results of this particular study, there are known benefits to consuming a protein-rich breakfast that improves metabolism; muscle growth should not be the sole criterion.

Breakfast offers an important opportunity to consume sufficient protein before training. to record , especially during endurance training. Traditionally, however, most athletes and sportspeople focus on protein intake after training.

Consuming protein (along with other essential nutrients like fluids, carbohydrates, and electrolytes) 30–60 minutes after training supports faster recovery and promotes muscle growth and repair. This timeframe is often referred to as the optimal recovery period. “ anabolic window " designated.

Anabolism is the process by which small molecules develop into larger, more complex molecules, thereby forming new tissue and cells, including muscles. The anabolic window describes the body's anabolic response.

After strength training, the body is in an anabolic state – processes at the cellular level promote muscle growth and repair. During this anabolic window, muscles are particularly receptive to nutrients such as protein.

How much protein you should consume depends on the intensity of your workout. Whether or not you ate before training also affects the benefits and timing of protein intake, although most people consume protein within two hours of exercising.

One of the most overlooked times for protein consumption is before bedtime. While the body is at rest, protein can promote muscle recovery and alleviate muscle soreness after exercise or sports.

Consuming 30-40 grams of protein before bed is beneficial for those who regularly engage in strength training, as it supports muscle strength and muscle growth.

Several studies have examined casein and its effects when taken 30 minutes before bedtime. It has been found to have a positive effect on muscle strength and development.

Casein is a complete and slowly digestible protein, therefore bedtime is the perfect opportunity for a sustained release of amino acids that are essential for muscle recovery.

Frequently Asked Questions

How much protein should you consume daily?

The recommended daily intake is 0.8 g of protein per kg of body weight. However, active individuals or those wishing to maintain muscle mass should aim for 0.8 g per pound of body weight. Actual requirements may vary depending on age, sex, and activity level.

A nutritionist can help you find the right amount and type of food to suit your fitness needs and dietary preferences.

Is it possible to eat too much protein?
