What's the best way to burn fat during cardio? Too high of an intensity will rob the muscles of glycogen and force your body to break down its own muscle for fuel. Too low of an intensity and you'll have to do cardio for hours before it will even be worthwhile.
Fortunately, a recent UK study has found the answer.......
British scientist found that my using a method called Indirect Calorimetry, they can measure the amount of fat that the body burns during a particular method of exercise (treadmill, stationary bike, etc.) The method works by analyzing a subject's expired air for oxygen and carbon dioxide concentration. The amounts are calculated to determine how much fat or carbohydrates are being used for energy.
Their conclusion? The best way to burn fat is to jog on the treadmill at 70% of your maximum heart rate (220 minus your age); this burned about 40 grams of fat per hour of exercise. Going above or below burned significantly less fat, as did other forms of cardio.
The message: Use the treadmill or head for a run as your main method of cardio!
