I just got an Apple Watch that I barely know how to us (app suggestions anyone?) and I saw that there is a heart rate called the fat burning zone in the app HeartWatch. It’s a fairly low heart rate, you barely break a sweat. I’m used to pushing myself as hard as I can hoping for the best results, but now I’m wondering if I should slow things down…but then I was wondering if when you’re keto, every heart rate is a fat burning zone, because all you use is fat.
Can anyone explain this fat burning zone and if it is still a think of you’re in ketosis?
