Does the body burn fat more effectively during low impact cardio?

I think what you mean is low intensity and not low impact. You can have close to no impact and very high intensity (i.e. eliptical).
The idea behind this low intensity crap is that at certain lower heart rates your body is using more fat as fuel so you burning more fat.
However, if you workout hard and do real cardio you will burn more calories and you will get more of an afterburn and you will get more fit. There is a reason people who do a lot of high intensity exercise are lean.
If you are lazy and want an excuse not to work hard you can do low intensity and sure, you will lose some fat if you eat right. But if you are serious about losing body fat then up the intensity. HIIT works great and is much more effective then sitting your ass on recumbent bike and not breaking a sweat.

You have to be right at, or slightly above, a respiratory exchange ratio (RER) of 1.00 to be running on pure carbs. V02 and HR are linearly related, but the max varies from person to person (220-Age is a rough estimate of MHR).

I can sustain about 105% MHR for 30 minutes if that gives you any idea, and be singing along with Akon doing it...
Part of the issue with which burns more is that lower intensity cardio primarily shows benefit just for the time you are doing it, but HIIT raises metabolism for hours afterwards. Then add in all the differences of body chemistries, eating habits, other activity, other supplements, etc and its impossible to say.

My problem with high intensity while cutting is it usually elevates ur metabolism too much for you to stay at ur desired calories and end up eating more then u want to lose the weight u want. Low intensity is the way to go IMO unless ur using high intensity for a workout on its own

I think it depends totally on your goals as has been said HIIT is great for burning more calories and keeping metabolism high. IF you want overall weightloss and cardo condition HIIT if you just trying to strip off some last stubborn fat while mainting muscle then LISS

Yes that's true but your giving your body another reason to over eat when u do hiit cardio. I don't mind it I can control myself but some people will not be able to do it

Yea absolutly! That's what I said. But I also said I wouldn't do it after a workout or on emnpty. It still increases ur metabolism too much. I know people who run everyday and wonder why they never lose weight and its bc there metabolism is soo high so Is their appetite and they get stuck

Ok let me repharse "too much" to an amount that may have people eating more then normal whn they get hungry leading to them eating an amount that allows them to maintain and not lose. This is just my experience with a few of my clients I've had

Oh yea dude trains like an animal. He intake is high from all the high intensity work. But she eats when she's hiungey and that's pretty often. Her problem is when cuttin calories even a little she stays hungry. It comes down to doing thing properly ion your own yanno. That's all I was getting at some people can't handle it

if jogging and running are so effective......why do you see these folks and they usually look depleted and flat with no muscles......I have heard that many bodybuilders including Dorian Yates, Porter Cottrell, Lee Haney and Phil Hernon....to name a few.....were all big proponents of power walking and or treadmill walking at a brisk pace but not too brisk that you can't carry on a conversation.
These pundits today, all say that you must huff and puff to get ripped.
The conditioning of the bodybuilders today is aweful compared to the shredded competitors of the 80s and early to mid 90s.
