What the study was about: April's Cooking Light magazine cites a study done last year by a professor of nutrition at Kansas State University. The research found that not all calories may be equal: "The body may burn calories from whole foods better than it does calories from processed foods like Twinkies."
What the study found: Calories from unprocessed foods -- such as whole grains, fresh fruits and veggies -- may be burned at a higher rate when you are eating and digesting than calories from processed foods such as white bread and processed cheese. Eating whole foods versus processed foods may actually give your metabolism a nice bump.
What it means to you: Take the lead from Weight Watchers, which last year decided that its participants could eat as many fruits and veggies as they wanted. Put away those processed chips, and choose an apple and some grapes instead.
