Does anyone set their calories to their BMR

I confuse myself so much, one day my brain will catch up

So I am in between everything -- sedentary, lightly active and moderately active and Ive decided that my exercise and activity is far too unpredictable to have a set TDEE - 20%

Does anyone custom add their BMR calories to their MFP and eat back exercise calories?

Is this something you can do?

I know this answer! I am the same way. I average a TDEE of 2184. However, I have many days where it is a lot lower and some that are a lot higher. I have my MFP set to a 1 pound loss per week, with negative calorie adjustments turned on. Then, when my Fitbit syncs (fitbit works off the TDEE system) it tells MFP if I need more or less calories. On lazy days, it takes calories away (Friday I only ate around 1350) and on active days it gives me a lot more (Saturday I ate 1873). I tried all the equations thinking I needed to up my daily calories, but that just doesn't work for me since I am sedentary some days. I don't exercise every day, so don't need to eat 1700 calories on those days, and on a day where I can eat 1900 calories- I want to eat all those calories. You could find your TDEE and subtract 20% (which for me is about 500 calories), but I would just get a fitbit and let it do the math for you. Also, I was on a plateau for months until I changed the setting to 1 pound per week (or TDEE-20%).

I set my daily calories at an average of BMR since different calculators gave me slightly different results.
I usually eat some of my exercise calories back but not all.

My BMR is ~1500, and I eat 1600 plus exercise. I calculated my TDEE without exercise using another user's spreadsheet which was really helpful, I can't link it right now but I'm sure if you look through the TDEE threads you'll find it. It's pretty specific but still easy to use.

What surprised me was that after all that math and trying to figure out what TDEE etc is, I realized I'm basically on MFP's calorie goal to lose 1lb a week. So there's that.

It's been 3 weeks since I switched from ~1100/1200 a day to 1600+exercise and I didn't gain any, but I've only just started to lose again. I've gone from 175 to ~173ish in the 3 weeks, which I guess is pretty good now that I look at it if it's really supposed to be 1lb a week. My scale's not digital so it's easier to use every 5 pounds as a marker rather than looking at every pound.
