You’re building muscles by damaging or injuring the muscle fibers. When the muscle fibers get time to heal we experience muscle growth. This is where protein plays its part.

To experience muscle growth, our muscles have to be able to repair themselves. They’ll only be able to do so if there’s enough protein to work with.

Why protein are important during a weight loss

Protein isn’t just important for gaining muscle, it’s just as important when trying to lose weight.

When we’re in a calorie deficit our body will start to use the recourses at hand, glycogen, fat, and muscles. A low protein diet will result in more muscle mass being lost. Not only is it hard to build muscle mass again, but it will slow your weight loss down too.

It even counteracts water retention, which will make you look “harder”.

It’s recommended to eat 2.2-2.6g of protein per kg of body weight or 1.1-1.2g of protein per lbs of body weight while trying to lose weight. Especially if trained.
