I know it's been asked a hundred times, but...

I just wore my HRM for 7 hours of normal activity, mfp/email time, cleaning house, grocery shopping, eating lunch, etc. I couldn't wear it all day and night because it was driving me crazy.

So, I burned 920 calories. If we take that as an average = 131 calories an hour and figure 15 hours awake = 1965 calories, maybe another 500 sleeping for 9 hours (yes, I know you all hate me now for getting that much sleep). That means I get 1965 calories per day for a pound a week lost (not count exercise)?

Seems like an awful lot for a 5'3" 156 lb person. MFP says for a lightly active person at my weight I should get 1380 + exercise.

Thoughts?

I really think that MFP is set low for most people. I wonder if the formulas that figure out how many calories a day should adjust based on body fat % (vs. muscle which burns more at rest). I think that there are people in this world who are super-duper sedentary, and maybe that's what these figures run off of.

I wore my HRM on a very slow day, and it said I should be at minimum 1700 with no activity. (137ish and 5'6") (I was coming down off of a busy week, and the most I moved was changing the channel from "E true hollywood story" to "mummies are fascinating!" shows on the discovery channel.

I think this whole craziness boils down to us learning how to figure out when we're hungry and when we're full. Bleeeaaaargh. . .I suck at that.

I do know that what MFP says is "maintenance" for me seems to be my magic "last five pounds" number. I think maybe a good experiment would be adding a hundred or so to what MFP says, and then keep adjusting.

I wish this was more scientific. In my science-fiction geek fantasy, I get some sort of non-invasive body scan, and then a machine makes me fantastic tasting food in exactly the proper proportions to make me buff. Sigh.

anyways, that's my 2 cents worth. :flowerforyou:

Wouldn't that mean that at 1965 you would maintain you weight? So if you cut back 500 cal at day to 1465 you would lose a pound a week? Or am I misunderstanding? I need to try wearing my hrm on a slow day and into the night, I have a feeling I'll rip the chest strap off sometime in the middle of the night too.

That would be without the 9 hours of sleeping calories (I figured 500) - so my 1965 would be my lb a week.

well mary, sounds like you wore it for the busiest part of your day, I would imagine you would probably want to knock some calories off for the hours that you aren't quite so busy or average it out a little lower. I did your numbers and it came out to around 2250 for a RMR (maintenance calories) which sounds about right considering if you knock say 10 calories an hour off your estimate (because I imagine 2 or 3 of those night time hours are less active, I don't mean sleeping hours, just the time after everything settles down.). Also, looking at your schedule, if that is an average day, I would call you moderately active, not lightly. Now if you don't clean the house every day, and go grocery shopping, then I guess you would want to knock off a few calories anyway.

you can get em at any local sporting goods store. Polar makes a great one.

I love my F6

www.polarusa.com

look under the general fitness catagory in the polar store to see the F series watches. You can also find them on Ebay or Amazon, just search for polar F4 or polar F6 or F11 (depending on what extras you want with the HRM)

flabbyguy

Thanks Banks i checked out the site.I will definitely want one of those...
