    I think that is an easy and reasonable equation. Especially considering that most people who do her videos probably arent using a site that calculates your burn for you like MFP, and as others have said MFP is often way off on their estimates.

    Pretty decent estimate, but not completely and perfectly accurate like a HRM will be.

    The subtle sarcasm of your posts never ceases to bring a smile to my face (as well as the responses from those who bite hook, line, and sinker).
    Yeah, pretty funny. Only working out in a bomb calorimeter would be as close to completely accurate as possible.

    It's actually very close to what my HRM gave me when I did 30DS.

    I think it's a good formula. I have always heard that you burn more (and lose faster) when you're heavier, than you do when you only have 5 pounds to lose.

    MFP tends to seriously overestimate the calorie burn for most people. Before I got my HRM for real numbers I would take whatever MFP gave me and subtract at least 25%.

    Ditto! :D

    I typically take my MFP estimates and divide them in half. For me, there's only about a 10-15 calorie difference between doing that and using Jillian's formula, with Jillian's saying I burn a little more than what I've been estimating.

    Sounds about right. When I take my HRM and subtract my BMR plus another 20% for error percentage, it's pretty close to her estimate. I can definitely believe I burn 600 calories per hour if I keep my heart rate around 150, maybe even more. I weigh 316 pounds. It takes a lot to move this body. :)

    I think that is probably a good average.

    What if it's an extra 25lbs of muscle, vs an extra 25lbs of fat?

    OP here: When I do her formula, it says I burn considerably less than what MFP says. About 50-75 calories less. But it makes sense. I think I'll have to log less calories burned. I don't have a HRM. I just cut and paste the original question from her website.

    I think that being within 50-75 calories shows quite a bit of accuracy. HRMs are estimates. What we log as calories in our food is estimates. Being off by 50-75 calories, even every day, is not going to harm your progress. This is why some people will shave 25% or so off the total to give a little bit of room. Nothing is within a calorie or two of being completely accurate.

    At least her formula gives you something to go on.

    I'm too lazy for an entire hour of intense workout, so when it comes to burning calories, so I happily note that Jillian Michaels wrote in one of her books that if she had the choice between six hours of sleep and a workout on one side and eight hours of sleep on the other, she would not hesitate to pick the eight hours of sleep!

    There's little doubt her formula for burning calories during a workout is ok. When that is said though, more and more research is emerging to show that exercise has a negligible impact on weight loss. The kind of calories you eat will lose the pounds, during which the purpose of exercise is to promote fat loss rather than muscle loss.
