Do I need to eat during the hockey game?

During training or a game, you may need to refuel, depending on how long you’ve been playing and at what intensity. Try to take in some carbohydrate at every opportunity. Sports drinks, diluted fruit drinks, a handful of cereal, or “back pocket food” (gels, beans, and blocks, etc.) with 8 ounces of water will provide additional fuel to working muscles.

Maybe! In general during a regular 3-period game there is likely not a need to eat during intermission. Although, all teams should have a plan for multiple overtime scenarios for food, like easy to digest carbohydrates: fruit, raisins, shot blocks, gels/gus. Also before you decide to add food to your game routine, try it out in practice first to see how you feel on the ice!
