Calories burned during HIIT????

Spliner1969

MFP calorie burns are probably approximately 40-50% over stated
For everyone?
For every exercise?
You know this how exactly?

1) For Everyone? I'd say not for everyone. You're going to have to judge this for yourself. It is going to depend on how hard you work, or how hard you push yourself. Base it on HR if you want it to be more accurate.
2) For every exercise? I'd say refer to #1. It's going to vary for everyone. You'll need to judge this over time for yourself. It's going to depend on how hard you push yourself, what you weigh, and how high you get your HR.
3) You know this how exactly? I dunno about the poster that posted this, it might be right for them, but for me it's not nearly that inflated. Now that I'm at a normal BMI I'd say they are inflated maybe 10% on MFP, and maybe 20% on the app I use called Endomondo. Sometimes less. On my Bowflex M5 it's inflated maybe 30%, but then again that's me, not everyone.

The best way is to judge it for yourself. Pick an app you like and stick to it. Set your base calories without exercise calculated in at MFP, then allow yourself to eat back 70% of the exercise calories on top of what MFP sets you. After two weeks to a month if you're gaining weight or not losing weight at the rate you expected, stop eating back 70% and try eating back 50%. Or vice versa, if you're losing faster than 2lb a week, eat back a tad more. After a few months you'll get the hang of it as long as you don't switch apps constantly (they are all different), and use a good HR strap to calculate burns. I believe my Polar H7 is about 80-90% accurate for me with my Endomondo app. Heck, I've been at maintenance for a few months and am still losing weight so it may even be more accurate at my current BMI than I expected. My point is you're going to have to figure this out based on your own experience. 30% over-inflated estimates are a good place to start though in my opinion. Adjust from there. Mine may simply be more accurate because I push myself to my maximum effort every time. I try each time to do more and work harder (I'm somewhat addicted to it by now lol). I set goals for the time I have and do my best to exceed them. I don't always make it, and I've even pushed myself too hard and had to take an extra rest day, but you get the idea. Max effort means the calorie burns are more accurate for me.
