Your weekday breakfast is latte-only; your weekend breakfast is lumberjack-worthy. But each adds up to a cup (or heaping plate) of empty calories.

Instead of starting off that way, reach for energy-boosting, nutritious, and tasty foods that health experts themselves eat. Whether you're in a rush or have some extra time, here are eight easy breakfasts from top nutritionists.

Weekdays
Considering breakfast's benefits -- it provides energy, keeps daily caloric consumption in check, and can even lower cholesterol -- Peeke is amazed that people skip it. If better health isn't a motivator, then try some vanity: According to the largest weight-loss study ever done, a major predictor of a person's success was whether he or she ate breakfast. To get a quick and even mix of protein, fat, and carbohydrates, Peeke microwaves a piece of low-fat mozzarella cheese and a tomato slice in a whole-grain pita. She grabs an apple for fiber and a cup of her favorite antioxidant-rich Kona coffee (haoleboycoffee.com).

Weekends
When Peeke has time to stand at the stove, she makes a small bowl of Irish steel-cut oatmeal and tops it with a handful of chopped walnuts, a half-cup of blueberries, and a dash of cinnamon. The oatmeal is full of cholesterol-lowering fiber. Blueberries provide potent antioxidants to boost her immune system, and walnuts offer protein and omega-3 fatty acids. Peeke is an avid runner, and she says, "This breakfast fills me up and gives me all the energy I need." She also squeezes a glass of "true juice" in her juicer. Her favorite combination: an apple with three carrots and a small piece of ginger.
