The problem with a Heart Rate Monitor (HRM) could be...

... counting the calories twice.

I am not sure this will sound intelligent but I am going to try to explain myself. You could be counting the calories burned twice. This would really throw off your deficit for the day.

In the Daily Differential of Reports (under My Tools) I noticed that BMR* has that asterisk * by it and went back to check it out.

Here is what it said when I found the *:
BMR is your Basal Metabolic Rate, which is the number of calories your body burns on a daily basis to perform its basic tasks like breathing and pumping blood. The BMR calculation is based on your age and weight and accounts for a sedentary lifestyle. The BMR in the chart above has been multiplied by 1.2 to account for the calories you need for both basal metabolic functions and light activity outside of exercise (such as light walking on the job, desk-work, and running errands.) Please note that BMR is not a perfect measure.

So we all need to make sure that when we count our cardio, that it really is cardio and not just light walking on the job, or desk-work, etc.

When I was struggling last winter 2009-10, I was counting housework and it is already calculated in - same with walking around the grocery store pushing a food cart.

If you are using the numbers from your HRM and losing weight - WooHoo! Go for it!!

But if you're not losing weight - this could be part of the problem.

    yes, my bmr is about 1 calorie a minute. so if i exercise for 30 minutes, i subtract 30 from what ever my hrm says i burned. i feel that is only fair...

    I never did that. I had to work out to count it. So I guess I am safe on that score. Since my scale seems to have the right moving idea, I must be doing some things right. LOL!

    Love you,

    emoticon I know my body is at maintenance at the moment when it is not supposed to be! I have upped the cardio, so now going to lower the calories and eat more protein and less carbs, just to get this body of mine to react! emoticon

    You have hit on something that I have always wondered about and have done some reading on. You are right, according to my understanding of what I have read. Whenever we exercise - whether we use the HRM or the machine to calculate - there is some overlapping of calories burned. While we are exercising the body is still carrying on its basic functions(BMR)so, acvcording to what I have read for us to get an accurate measure of the number of calories that we actually burn from the exercise we would have to subtract some numbers. They gave a formula. For me thats too much work and complication so what I do is account for the calories burn during cardio session and tell myself that those calories that I burn doing strength training is just to make up the difference and for good measure.

    Thank you for sharing. I am new to the heart rate monitor, just having purchased one. I only use mine at the gym when I am working the cardio machines. My reason for this was that the readings according to my research and an article I read on Spark are not always accurate on calories burned as they were ma they were tested by individuals which may not burn at the same rate as women, in particular. So far, I have been remaining on track, but only time will tell what is reality and what is hype. emoticon
