Question for science people about heart rate during exercise

DorkothyParker

I am finally getting a heart rate monitor.
I know that low intensity exercise is supposed to burn the most fat but that high intensity actually burns more calories overall.
If you are already fat adapted, is it more worthwhile to go for the high intensity exercise or do you run the risk of burning through muscle more easily?

Feel free to pull out charts and peer-reviewed journals because I'm sure some of you have already looked into it.

(Or you can ELI5)

Read the Fat Burner thread if you haven't already.

You need to first understand what it means to be "fat adapted." That's OK, nobody really does.

In terms of internet keto memes, it's almost meaningless. It that context, it's really about protein metabolism, and you can read Lyle McDonald if you want details. Or just ask me. Bottom-line: if you're sedentary, it means the difference between 90% of energy coming from fat (non adapted) and 92% (adapted).

In terms of exercise and muscle adaptations, it's much more interesting, and high-intensity exercise seems to get you there. More info in the thread above.

I found the good part!

Let's try to quantify this for the average low-carber. For the LC athletes, peak fat oxidation was 1.5g/min and it occurred at 70% VO2max. For the HC athletes, peak fat oxidation was 0.7g/min at 55% VO2max.

70% VO2max for me is roughly 150 BPM. This is definitely a doable rate, I won't be falling over.

Now, I am not a HC person, but I am new to this. Still, I think I will go for the 150 BPM range. Thank you.
