In the world of fitness and sports nutrition, you hear the word proteins or proteins almost daily. Protein shakes, protein-rich bars, powders, and even protein-rich pancakes are everywhere. This makes some think it's a marketing hype — a temporary trend like low-carb diets or detox juices. But don't be fooled: proteins are not a hype. They are an essential part of your diet, especially if you exercise.
Why are proteins important?
Proteins are the building blocks of your body. They consist of amino acids that are necessary for the building, repair, and maintenance of muscles. Every time you train — whether it's strength training, running, or HIIT — microtears occur in your muscles. Your body needs proteins to repair these and rebuild stronger.
Without enough proteins:
-
Your body recovers more slowly
-
Muscle building is less effective
-
You increase the risk of overload or injuries
-
You can lose muscle mass, especially on a calorie-restricted diet
In short: if you stress your body with sports, you must also support it with the right fuel and building blocks. And protein is crucial for that.
How much protein do you need if you exercise?
For non-athletes, the general recommendation is about 0.8 grams of protein per kilogram of body weight. But athletes need more. Depending on your sports goals, the requirement lies between:
-
1.2 to 1.6 grams/kg for endurance athletes
-
1.6 to 2.2 grams/kg for strength athletes and people who want to build muscle mass
-
Sometimes even up to 2.4 grams/kg during a strict diet while maintaining muscle mass
For a sporty man weighing 75 kilos who does strength training, that means 120 to 165 grams of protein per day.
Is more always better?
No. Excess harms. The body can only process a limited amount of protein per meal (on average 20–40 grams, depending on your weight and training condition). The rest is converted into energy or stored. What is more important than eating extremely much is distribution throughout the day. Ideally, you consume a protein-rich meal or snack every 3-4 hours.
Proteins from food or supplements?
Good protein sources include:
-
Chicken, turkey, beef
-
Fish (salmon, tuna, cod)
-
Eggs
-
Dairy (quark, yogurt, milk)
-
Legumes and tofu
-
Nuts and seeds
Protein shakes and bars are convenient tools, especially around your training or on busy days, but they are not a replacement for a balanced diet. See them as a supplement, not a base.
The bottom line: not hype, but science
Proteins are not a fad — they are scientifically proven essential for everyone actively involved in sports, recovery, and health. Whether you want to build muscle, lose fat, or just get stronger: protein is part of your foundation.
So don't be misled by people who say "protein is only for bodybuilders." Everyone who takes sports seriously benefits from sufficient protein intake. It's not a hype. It's a necessity.
