IFK Göteborg’s Max Fenger says his body went into “survival mode” after he ate too little and trained too much

Fenger has been given playing time in IFK Göteborg's latest Allsvenskan matches after missing large parts of the season.

At the beginning of the year, I was sick. It was a tough pre-season and I didn't feel like myself. I lost a lot of weight and didn't have the same strength or speed. I felt really tired and had no energy, he tells Blåvitt+.

According to SVT, the lack of energy was due to relative energy deficiency in sport, also known as RED-S.

I have trained more than my body has received energy from my diet. This has caused my body to go into survival mode and become stressed.
