Frontload your meals with protein and fiber: This is crucial if you've managed to eat or drink too much sugar early in the day. Protein and fiber, when paired with a carbohydrate of choice, can stabilize your blood sugar and help you avoid that dreaded crash. Be sure to choose snacks and meals that are high in fiber and protein naturally: hard-boiled eggs, for one, or even a small omelette; a handful of nuts at your desk; an apple with peanut butter, or even some crudité and hummus.
