Another researcher shows that calories count.
These researchers conclude, “If you exercise and replace the calories you burn, you’re no better — with regard to how much fat you burn off — than if you didn’t exercise.”
The notion that exercise somehow boosts the body’s ability to burn fat for as long as 24 hours after a workout has led to a misperception among the general public that diet doesn’t matter so much as long as one exercises, says Edward Melanson, an exercise physiologist and associate professor of medicine at the University of Colorado in Denver.
“People think they have a license to eat whatever they want, and our research shows that is definitely not the case,” he says. “You can easily undo what you set out to do.”
In the new report, published in the journal Exercise and Sport Sciences Reviews, Melanson and colleagues discuss research to date on the issue of burning fat during and after exercise.
The authors conclude that while people do burn more fat when they are exercising than when they are not, they have no greater ability to burn fat over the next 24 hours than on days when they are couch potatoes.
