Not sure yet what to make of all this - but it is interesting!  |
The existence/relevance of the so-called fat burning zone seems to be questionable. But I don't know that it really makes any difference. Most people who are trying to lose weight can't sustain exercise at 80+% of their maximum heart rate for very long anyway.
The switch into fat burning mode after 20 minutes of exercise is a different phenomenon. I think it is more generally accepted. The behaviour of my blood glucose levels when exercising certainly supports it.
