Calories vs. exercise

My doctor always told me that calories really do count, and it’s virtually impossible to lose weight with just exercise.

Ready to jump off the calorie-counting bandwagon? Here's what to do instead:

• Instead of counting calories, eat smaller portions. It may seem like a basic concept, but it's easy to forget that bigger portions have more calories. Most of us gauge a serving as "the amount we're used to eating," a recent study found. That would be restaurant food -- where meals are served on platters, not plates. And the more we look at (and eat) huge portions of food, the more we see them as normal -- to the point of serving ourselves the same amounts at home. Unfortunately, studies show that when we're served more, we tend to eat it. When researchers from the University of Illinois, Urbana-Champaign served subjects bigger helpings, people ate up to 45% more food. One caveat: there's no reason to eat fewer vegetables; they're much less calorie dense than other foods (they contain fewer calories per gram). A cup of raw broccoli, for example, contains only 31 calories, while the same amount of chocolate ice cream boasts close to 285.
• Instead of counting calories, choose foods that use more calories. Some foods require more energy than others to digest and metabolize, says John Berardi, PhD, CSCS, president of Precision Nutrition, and author of The Metabolism Advantage. We call this the thermic effect of food, Aldana says. The difference is very small, he cautions, just a few calorie's difference, for example, to eat a slice of bread made from whole grains vs. one made from refined flour. (Refined flour digests easily, leaving you with the full 4 calories per gram, while whole grains use up part of their 4 calories per gram during the digestion process, he says.). For example, if a woman were to start eating only foods that take a lot of work to digest (high-fiber, protein foods) she might save about 12 to 15 calories per day, the same amount she could expend by walking for about four minutes. But for some people -- especially those stuck in sedentary jobs or crunched for time -- it just may be worth it. Besides, foods that take more work to digest, like those high in fiber, tend to be those that are better for you. And choosing the best nourishment for your body is a much healthier food focus than counting calories.
• Instead of counting calories, make sure you consume the right kind. Nearly one-quarter of Americans' calorie intake comes from sweets, desserts, soft drinks, and alcoholic beverages, research from the University of California, Berkeley notes. Another 5% comes from salty snacks and fruit-flavored drinks. Nutrient-rich fruits and vegetables, on the other hand, contribute only 10% to the average American's calorie budget. "When it comes strictly to weight loss, a calorie is a calorie, Klein says. However, when it comes to your health, it's best not to blow your calorie budget on foods that lack nutrients. Nutrient-dense choices like fruit, vegetables, and whole grains can help prevent heart disease, cancer, and diabetes, while those lacking in nutrients, like candy, soft drinks and white bread can contribute to a whole host of health problems.
