When working at this intensity, a greater percentage of calories burned comes from stored fat. Working anywhere within the cardio zone will improve cardio fitness and burn calories. The benefit of working in the fat-burning zone is that you target stored fat and thus encourage weight loss. But, keep in mind, that if you work in a higher zone, you burn a greater amount of calories overall—which is important to weight loss. Although a lower percentage of these calories will come from fat sources, the total number of fat calories burned will likely be the same or greater.
Take, for example, a person who burns calories in a minute walk at a heart rate of 55 percent of maximum. Seventy-five percent of those calories, or 75 calories, may come from fat.
