Sugar can give you a short burst of energy followed by a severe drop in vitality. Strike a balance among proteins, carbohydrates, and fats in your diet. Ask your health professional for advice. Eat a light lunch, not too heavy on carbohydrates or dairy products, both of which will lower your energy level. The best lunch is made up of lean meat or fish, salad, and a piece of fresh fruit.
Heavy desserts are out.
Skip candy bars for quick snacks. Instead, keep low-calorie vegetables like carrots and celery sticks on hand. Bananas also make a high-energy food snack. Now that most offices have microwaves, prepackaged microwavable popcorn is a favorite afternoon office snack. Indulge, but choose the air-popped corn without butter or salt.
