What is most efficient way to burn fat?
Not the fastest. I want to know how to target fat specifically if possible or just calories in general if not for the least effort output. Time spent exercising or the activity doesn't matter as much as long as total energy used is less (or maybe... perceived to be less).
I've read all about how HIIT will blast fat off - even after you are done working out, but that slow running will target fat specifically - and you can do that for a longer time.
1 hour of slow running generally seems easier to me than 20 minutes HIIT. At least psychologically. But is it really more efficient fat burn? You can (and should?) feel like death after a good HIIT session, and pretty fine after a pretty long run.
The math I tried:
HIIT feels like 100 effort
Easy Jog feels like 20 effort
100 effort expended over 20 minutes & 500 fat-based-calories burned
HIIT_EFFORT = 100 * 20 = 2000
20 effort expended over 60 minutes & 500 fat-based-calories burned
JOG_EFFORT = 20 * 60 = 1200
HIIT: 500 calories / HIIT_EFFORT = 0.25 calories burned per effort
Jog: 500 calories / JOG_EFFORT = 0.42 calories burned per effort
In this case the easy jog is more efficient at fat burning than hiit.
