I have seen people doing it, it gives results but keep in mind that it is necessary a 500 calorie diet daily, the person I saw doing it was weak all the time while doing it as she wasnt getting as many nutrients as the body needed daily...Keep researching about it though

you can also get the Timex T5G971, that one tells you heart rate, maximum rate achived, calories burned and it has an awesome price on Amazon.com, check it out...

You need to create it, and then monitor your calories burned and put the manually, thats what I do with insanity

I ordered a HR monitor on Amazon, and its great and the price is great as well, it calculates calories burned, time in zone, maximum heart rate, etc, easy to use and really accurate....
