? Hr monitor

Definitely go with what the HRM says. I have one with the watch and chest strap and MFP is waaaaay off when it comes to my calories burned. I was actually not losing at first because it had me burning 100 more than I actually did and I eat my exercise calories back.

You gotta trust the HM, I'd say. I ordered one but haven't gotten it yet.

Assuming your HRM has all your info inputted into it (weight, height, age, gender,...) I'd go with that. If it doesn't I'd go with MFP since it does have that info in the data about you. My HRM and MFP are pretty much on target within 10 cals burned.

Hi i have a question.
I wore my hr monitor out when i walked the dog it is programmed with my stats, It said my hr was avg140 and i burnt 400 cals. When i put dog walking at mod pace on my diary it says for 35 mins i burnt 200. which one should i count?
Any help gratefully excepted ta

HRM is more accurate but would also count a portion of calories you would have burned had you not worked out, that MFP already accounts for. Essentially you should use your HRM calories burned but back out your maintenance calories for that time.

If you Maintenance calories are 2200, you would burn 1.53 calories/minute (2200/24/60) while just living, so in 35minutes you would have burned 53 calories had you not worked out. So you should enter 347 (400-53) into MFP for calories burned due to exercise.
