If you're a three-meal-per-day guy, chances are that your energy levels take a dive between meals. By refueling with healthy snack foods, instead of traditional junk food, you'll keep your energy levels high without sacrificing your health. Traditional junk foods tend to be high in sugars and fat. When consumed, these foods will give an immediate boost of energy, followed by a big energy drop. Eating healthy snacks, on the other hand, can help to ensure that your energy stays level throughout the day。

6. 零食也要吃得健康，避免垃圾食品

　　如果你習慣一日三餐，那么餐間你一定會吃點兒小零食。傳統的垃圾食品扔掉吧，健康的零食才會讓你保持精力又不至于犧牲了健康。高糖高脂肪的垃圾食品會帶來精力的驟升驟降。健康的小零食會讓你一天精力平穩。
