Think of your body like a car, when you fuel that car with premium fuel it runs at a completely different level. Performing at your peak means you need to supply your body with that same kind of quality fuel. You might have previously been able to get by with eating the wrong things, or even running on empty.
However, if you are looking to make a serious transformation you need to look at what your diet is doing. You won’t reach the same performance heights or make progress if you don’t start considering what is boosting your workouts. Of course, the term performance means different things to people.
For a powerlifter, it means generating maximal strength for a few seconds spread over several hours. For a long-distance runner, it means avoiding hitting the wall at the halfway point in a marathon.
