Often people who want to lose weight are told that in order to lose fat they would have to keep their heart rate on "target", keep it in the "fat burning zone" or have a "fat burning pulse" when they do cardio activities like jogging or running.
It is true that with a lower heart rate most of the energy you use to fuel your cardio activity will come from fat. But will you really burn more fat in total when you do fitness that way? Let's have a look.
Please keep in mind that the examples and data given are a bit simplified, as otherwise this would have become a very long video.
