A study was then done at Physical Activities Sciences Laboratory, Laval University, Quebec, Canada, and challenged the common belief among health professionals that low-intensity, long-duration exercise is the best program for fat loss. They compared the impact of moderate-intensity aerobic exercise and high-intensity aerobics on fat loss.
The bottom line was that the low intensity group burned more calories during their workouts almost twice as many.
But the high intensity group got 9 times more fat loss benefit for every calorie burned while exercising.
How did this happen? Compared to moderate-intensity endurance exercise, high- intensity intermittent exercise causes more calories and fat to be burned following the workout. They also said it may be that appetite is suppressed more following intense intervals.
The high intensity training raises the metabolic rate causing you to burn more calories after your training is long over with.
