We've all heard the saying that breakfast is the most important meal of the day, but the author of that adage probably didn't have donuts and Belgian waffles in mind when they said it. With so many high-carb, high-sugar options available in the A.M., breakfast is often the cause of our low energy throughout the day as well as our expanding waistlines. Instead of reaching for a starchy snack that will give you a quick burst of energy and cause you to crash later, enjoying a meal that combines protein, healthy fats, and slow carbohydrates will help your energy levels stay stable all day and won't undo the hard work you've done to achieve your Zero Belly. Even if you're pressed for time before work in the morning, many of these tasty, satisfying meals can be prepared in advance, making them as easy to grab on the go as their less healthy counterparts. Start incorporating some of these breakfasts into your regular routine and you'll see your energy levels go up as your waist size goes down.
