You will not necessarily burn more fat using a ‘fat burn’ program on the treadmill which keeps you in an intensity of 50 – 60% of your max heart rate. There is evidence to show that exercising at a light to moderate range burns more fat than strenuous exercise as the body has greater access to use fat as a fuel during these lower intensities. As you can see in the table below, a percentage of fat is used during all intensities of exercise, but at different rates. Because the rate of fat use is slow during light to moderate exercise, it is important to increase the duration of your exercise session – minimum of 30 minutes progressing to 60 minutes.
I have been helping clients to loose weight for over ten years now. My success has lead to employment in the film industry across dozens of films and I have also been employed to optimise the body composition of athletes to help improve their athletic performance. The majority of my work however, is with average, everyday people in my clinics in and around London.
