How are people burning such high calories

There are a lot of variable that go into calorie burn...you can't simply compare yours to someone else's. Yes, they could be inflated estimates, but they could also be perfectly legit. Your overall size is going to be a huge factor...both weight and height. Also, your overall fitness level is going to play a pretty big role.

Someone who is 5'10" but grossly overweight and out of shape is going to burn far more calories doing far less than someone who is 5'10" with 15% BF and very fit. When I first started working back my fitness, all I could really do was walk...just walking my HR would get up to 135 - 140 because I was so out of shape. I don't remember my burn, but now my 3x weekly walks for 30 minutes only give me about 150 calories and my HR doesn't get above 110 because I've upped my fitness and lost 25 Lbs.

1 mile = approx 100 calories regardless if you walk or run. Of course if you have more muscles you will burn more and supposedly if you weigh more you will burn more but not really much more to make a difference.

i do think many people overestimate how many calories they are burning and underestimate how many calories they are consuming.

I strongly believe if you run 1 mile in under 6 minutes you will be burning more calories than if you walked that mile in 20 min.

You are correct, and so is the post you quoted. Someone running a 6 min mile would burn (according to that theory) about 333 cals in 20 mins while the person walking would burn 100, that is more!

Trust me they are not. Use your HRM or body media device and adjust your calls according to that. That is a flaw with the MFP app. If they were truly burning that much on a daily basis they would be very thin which in most cases is not the case.

I have learned from experience on this. I bought a Timex HRM with chest strap and was thrilled when it read over 1,000 calories for 60 minuteo

I just started using a Bodybugg too. My TurboFire 60 burn has been between 550-600. My Les Mills Combat is generally between 450-550, but that is only for the 60 minute DVDs. I love my Bodybugg!!!

I burn +/- 700 cals per hour when I do high intensity workouts like Zumba. I don't stay within the "fat burning" zone. I normally average 168 and can go as high as 185ish. Obviously I expect this number to go down as I lose more weight...

If could be that they are going off what MFP says or they weight more.

If I do intervals on either my treadmill or elliptical I can burn maybe 600 cals in an hour.

I often wondered the same thing, and realized that once you exercise and enter your exercise, that if you go back and exercise again, that it will just continue to add it on throughout the day. Some people are exercising two/three times a day.

Maybe we're just VERY overweight and our heart works harder? I burn quite a bit.

I asked this exact question yesterday pretty much haha.

Probably over estimating. I burn about 300 calories in 35 minutes on the elipitical and I'm drenched in sweat when I'm done.

irrelevant. who cares?

questions you should be asking yourself are things like "what sort of exercise regimen can I commit to doing regularly?", "how should i structure my diet in a way that will keep me satiated?", "what are my fitness goals?"

^^^^^^^^ This!! We need to stop looking for reasons to bring down our efforts by finding faults with every body elses.

How is it irrelevant, and the OP obviously cares. Maybe she wants to know how she can burn 1000+ calories too

I use an Octane elliptical trainer and work out at lvl 20 resistance, and that gives me about 900 cals an hour. It doesn't matter to me how much it actually is because i never count my workout cals. I just use my daily allotment.

I do regularly burn over 1,000 in a day, but that is usually running 5 miles plus an hour long weight lifting class.

They likely either weigh more or are overestimating. Even while running the best I can do is about 450-475 calories per hour, according to my heart rate monitor.

According to my HRM I have been able to hit 650 on a really good run within an hour.

I've heard a general rule of thumb is 100 calories for 10 minutes of moderate exercise. Seems to fit your burn there OP.

I do an hour of kickboxing.. and high energy, high intensity.. i know it burns more. I also do Zumba.. the intensity depends on the teacher.. but I'd wager at least 600 in any class and I usually make it more intense. My step step would be higher then Zumba.. probably up there with kickboxing.. I sweat my butt off in all of them. I have no idea how many calories weight lifting burns and am guilty of just using MFP's numbers on that one. when I do the treadmill it seems to average out to about that 100 calories for 10 minutes, no matter which machine I am one..give or take a few. I know my classes get my heart rate up over reccommended.. but since I have a slow heart rate, it's super easy to go over.. to be in my range is quite diffiuclt. to maintain and as soon as I stop it drops.. Anyway.. I'm looking for cardiovascular workouts usually so I'm happy with the higher rate.

I did look up the average calories for my classes using google, and adjusted them on here. I don't wanna spend the 100 bucks on the HRM.

Also heavier people will burn more calories then thinner ones. Unfair if you ask me! but good for them! LOL

I suspect they are using the inflated numbers given by MFP.

^^^ this!!
