There is no set way of measuring the amount of grams of carbohydrates that you burn during a 30-minute jog, according to Jillian Michaels. However, certain aspects of cardiovascular activities impact the burning of carbohydrates.
When you exercise, your body burns carbohydrates before it burns fat and then protein. Carbohydrates are the primary source of energy burned at the beginning of a workout and during short and intense bursts, such as sprints. Jillian Michaels explains that 50 to 60 percent of the energy burned during low-intensity workouts, such as jogging, is in the form of fat. It takes 20 to 30 minutes of constant cardiovascular activity to burn 50 percent of your supply of carbohydrates.
