Your metabolism isn't an on/off switch, it's an engine. An athlete's body is like a race car that needs to refuel constantly and quickly, while a regular person's body is like a regular car that refuels occasionally. Athletes need way more nutrition, way more often.
Your body doesn't have a switch inside of it that just says, "Mm, fast metabolism. Mm, slow metabolism." I want you to think of your body kind of like a car engine. A car driving to run errands every so often throughout the week maybe needs to fill up once every other week. But a race car driving 200 miles an hour around the track, lap after lap after lap, needs to refuel fast and it needs to refuel often. Athletes, you are this race car. You need a lot more fuel than the average person does because your engine is running a lot more and a lot faster than other people's.
