Reisman shares the good news that “non-Olympians can learn from those athletes because no matter what you do in terms of an active lifestyle we should all be eating the same as they," she says. "The only difference with an Olympian is that they are going to consume double the calories we are because by nature they are more active."

Richmond snowboarder, Alexa Loo, for example, is very careful about what she puts in her body while preparing for the winter games. She never skips breakfast and eats many meals and snacks throughout the day. Her advice: “in addition to lean proteins and healthy carbs, make sure to load up in fruits, veggies and lots of water.”

Reisman stresses that "the body needs water to function, especially during intense training or exertion," she says. "Dehydration of as little as two per cent body mass can decrease muscular strength, muscular endurance and anaerobic work capacity."

Reisman suggests that we should start the day with a snack to "kick-start [our] metabolism" because after sleeping six to eight hours the metabolism is at its slowest rate possible,” she says. Like Loo, Reisman suggests that we should eat many small meals throughout the day with items from all four food groups in order to prevent us from being hungry and overeating.

"I know it's hard to change habits," Reisman admits. "But many of us eat too much late at night and aren't hungry when we wake up so we down a coffee and muffin, a small salad or sandwich at lunch and then we are starving at 4 o'clock in the afternoon."

The key is to eat small meals throughout the day and "stay healthy by stocking your diet with real foods first and as a last resort use energy bars if you must."
