Breakfast comes at a terrible time of day to make a rational decision. We're rushed. We're groggy. And we're famished.
We know it's good for us -- 90 percent of Americans think it's the most important meal -- yet fewer than half of consumers actually eat breakfast on a regular basis, according to the International Food Information Council.
Unlike other meals, however, breakfast is unique in that it can set the tone for your entire day -- for better or for worse. The trick is knowing how to eat it.
There is no perfect morning meal because the best breakfast depends on your body and individual nutritional needs, but you can't go wrong by eating "a moderate meal of mixed foods," said Richard Mattes, a professor of food and nutrition at Indiana's Purdue University. Start experimenting, using our guide below to see how common breakfast combos will affect your day.
Really bad: no breakfast at all.
Some people say they're not hungry when they wake up, but because you've fasted all night your metabolism -- and fat-burning ability -- slows down. Those who skip breakfast are also more likely to be overweight and consume more fat and calories the rest of the day, said Dr. Susan Biali, a dietetics specialist in British Columbia. Bypassing breakfast also makes you less productive and less likely to excel at school or work.
Very bad: coffee or tea only.
A daily cup of coffee or tea can give you hydration and a jolt of caffeine. Research has also linked both drinks to a variety of health benefits. Though it might hold you over until lunch, "it's only the hot liquid that is filling your stomach, tricking you into feeling satisfied," said Janel Ovrut, a registered dietitian in Boston. "You likely wind up overeating come lunch, when you're famished." To jump-start your metabolism, add a piece of fruit, Ovrut said.
