Correction, I've had the BMF for a little over a month. My average calorie burn is 2505 per day. So subtracting 10%, should I be eating 2200 per day? Wow, I've been way under if that's the case. Again, thank you for any comments!

I have a BMF and it is tempting to adjust daily...but dont't!! Stay at 2200 every day and recalculate weekly to make sure your TDEE is still accurate.

I think consistency is key! i try to stay 300 calories under my average TDEE. Some days I have a high burn, then I just make sure to net my BMR.

Love my BMF!!!

I use a fitbit, but was driving myself crazy keeping up with calories burned by month (i get a little OCD when it comes to spreadsheets) so now I just set MFP to my BMR and then log my exercise here and eat those calories also so I don't go under BMR.

I'm doing EMTWL and use a fitbit and i think i've now got a system that works well for me.

Ok so after doing a week or 2 recording with your device log on and see what average burn is per day over a whole week.
So fitbit's website lets you look at a week and says what the overal burn is and i just divide it by 7.

Then to workout what to eat the next week and beyond, just take your daily average and x by 0.90 (for a 10%cut, i do 15% so x 0.85). And that gives me what to eat every day.

Simple.

Usually every week do this calculation again just to see where i'm at and to make sure my activity level hasn't changed. So long as it is in the ballpark i don't usually change it as i like to keep my calorie intake pretty much a roundish figure.

Now another thing i should note is that i use a HRM in addition to my fitbit to record exercise. So pretty much i just use the fitbit for daily activity, and the minute i go for a run or lift some weights i strap on my hrm. And when deciding if i need to eat more in a day to get my net calorie intake to my BMR i ignore any fitbit adjustment, which for me is usually minimal anyway.

Now if you are using a bodymedia fit but not a HRM for exercise, which i believe doesn't automatically sync to MFP then it is slightly more complicated.

I think you'll need to check at the end of the day if you suspect you've done a lot of extra exercise that will take you under your BMR if you eat your normal allowance. If you can work that what you are likely to have burnt by midnight and then just times that number by 0.85 then then that might give you a ball park figure that you could eat. That would have you eating at exactly 0.15% cut for that day (i pick 15% for that day since you've probably already figured into your 10% cut value for the week a more active day on this day, you've just done a little more than you expected) which should ensure you've eaten above your BMR. And maybe after a week of doing that you can check all your numbers and see if that was a reasonable thing to do - that you've eaten roughly 90% of what your burnt over the last week.

Hope that helps.

Funny how the extra information and technology actually makes things more difficult for most people.
It has taken me weeks to work out what works for me.

I think it would be good if there was a sticky thread on here with some ideas of what people can do. My method as outlined above works for me, but there are probably a lot of other ways to do it out there as well.
