Many of us are aware professional athletes have strict diets and take care of their body to stay in peak physical condition to allow for optimal performance, but what exactly do they consume?

Benita Lalor, who is the performance dietitian for the Penrith Panthers, has revealed exactly what star players Josh Mansour and Matt Moylan eat on a regular day to help ensure they are prepared for the match each and every weekend.

Both players detailed what they would eat on a normal training day during the week, with some clear differences between the two stars.

Given Mansour plays in a position that prides itself on explosive strength and agility, the winger has protein powder in at least three meals a day, compared to Moylan who doesn't have any.

Moylan also eats less, and has just two small snacks outside of his usual breakfast, lunch and dinner, while Mansour has at least four.

“The player’s nutrition plan underpins every aspect of their training and performance. It’s an important component of our recovery strategies here at the Penrith Panthers," Lalor said.

"Protein is critical to recovery because it provides muscles with the building blocks to recover and repair. The stress that players’ bodies go through in NRL is extreme. Delivering quality protein can help to repair their muscles and maintain their lean mass.”

“After a game, recovering for the next week is always my biggest focus. What we do to our bodies after a game or big training session is key – we swim, ice, sleep and, most importantly, make sure we consume enough protein and carbs to refuel," Moylan added.
