Everybody agrees that you need protein to build muscle, but there’s still some debate on when you should consume it.
Sports nutritionist Roo Whelan says that the timing is actually less important than making sure you eat adequate amounts. Most studies also suggest that your muscle gains aren't affected by when you eat your protein-filled snack.
That doesn't mean there aren't any benefits to filling up on protein before or after your gym session. We got Whelan to explain how it affects your body.
Benefits of protein before a workout
The main benefit of eating protein before a workout is that it could improve your performance. According to Whelan, downing a shake before you exercise can stabilize blood sugar and provide sustained energy levels.
Consuming protein before you exercise will also ensure that your body has easy access to the amino acids it needs to repair and grow your muscles.
This could minimize muscle breakdown, which happens during strenuous training sessions, and also encourage your muscles to repair themselves during your workout.
Benefits of protein after a workout
According to Whelan, your body is in a heightened state of nutrient absorption after exercise. This means that it’s especially receptive to any protein you consume, using it to immediately repair damaged muscle fibers.
If your protein shake also comes with a serving of sugar and carbs, your body can use this to replenish your diminished glycogen (energy) stores.
It’s not clear how long this heightened state lasts for, but you probably have a few hours before your body returns to normal.
The other benefit of eating your protein after you exercise is that it's easier on your digestion. Who likes doing burpees on a full stomach?
So should you eat protein before or after a workout?
Studies suggest that there’s minimal difference between consuming protein before or after a workout when it comes to muscle gains. If you want to take advantage of all of the above benefits, you could try eating protein before and after you work out.
But unless you’re a competing athlete, it’s important not to get caught up in the weeds here. If you are trying to build or maintain muscle, the main thing is just getting enough protein regardless of when you consume it.
