HRM: Maintenance calories on MFP lower than actual daily cal

frenchielover

Hello all,
I have had a HRM strapped to me for one whole day, and my total expended calories, not doing any additional workouts....this is just my normal, every day routine..come to just under 2,000 kcals. However, MFP says my maintenance calories are 1,760. Does this mean I need to manually change it to maintenance of 2,000 kcals?

I wouldn't change anything. The MFP estimate is the calories you'd burn lying in bed all day. Clearly, moving around doing stuff will burn more

HRMs are not accurate for calorie expenditure at low heart rates. You'd need something like a BodyBugg for that - different algorithms required. HRMs assume you're exercising.

if you have your activity set to sedentary... and you are actually lightly active or active... you will be burning more than what MFP says you are burning.

I think probably the discrepancy is because MFP can't possibly tell how active or inactive we each are- I think your MFP BMR is based on what you would need to lie around in bed all day having your organs keep you alive, so it's up to you really - whatever suits you best!

This. HRMs will be wildly inaccurate if you attempt to use them this way.

Use the MFP estimate. As stated above, the HRM is only accurate for aerobic sustained activity at elevated heart rates. It won't be accurate for estimating normal activity calorie burn.

Thanks for sharing this one! I've often wondered how accurate my HRM is
