A gruelling training regimen for any athlete will burn fat off their bodies, so they must find ways to sustain it while they are pushing it to its limits. Many have found the need for calories can take too much time away from their physical training, so they often choose foods with less nutritional value so their body has something to use. It might seem like the best way to function during training, but those who are on a long term path will find that issues can arise after they are no longer competing in their chosen sport.
One of the largest issues today is the consumption of foods with little nutritional value, and those who are not training for an extreme sport often gain weight quickly. Their bodies store those extra calories as fat, but an athlete in training does not need to be concerned with that issue. They will burn off all they give their bodies, and they might even find they need more due to their training. It can become a habit to eat more than necessary, and that is where the danger lies.
Once the season is over, athletes might still train. They want to ensure they will not need to start from the beginning, so maintaining an off-season regimen is for the best. The issue is that they will need to bring their intake back down to a more reasonable level, but giving up those empty calories could be difficult.
Leaving behind any extreme training routine can be difficult for those who have spent years acquiring their physical habits, and giving up tasty junk food can be worse. They will need to turn off their sweet tooth and start replacing those unhealthy snacks with something more appropriate, and the need to retrain their taste buds could take as much work as their sports training.
