Walking Points Question

It depends on you. If you have your activity level set to sedentary you could certainly eat some of the extra calories you earn from your daily movement but there's really nothing that says you have to. MFP already builds in the deficit you need to lose weight at your goal rate so those extra calories will keep you at the set deficit.

For those who have a lot to lose, and don't get more hungry from the exercise, not eating the extra calories should have no effect. It seems to get more important to eat them back the less weight you have to lose but your mileage may vary.

I'll second SueInAZ's comment, but if you choose to eat back your exercise calories, I would encourage you to not eat !00% of them. Remember; the calories you burn and the calories you eat are all based on estimates - there's a lot of room for error baked into each input. Eating between 50% - 80% of your exercise calories helps to ensure the aggregate errors don't inadvertently put you over your daily goal.

1200 Net is as low as MFP will go (it's a default). So you don't need to worry about eating some of your walking calories back while still losing weight. You have room.

Logging steps as exercise in MFP has it's problems though. Sedentary people take steps....so MFP already includes some calories for steps. If you log 100% of your steps there will be some double counting. Walking briskly burns more calories than walking slowly....so there's the issue of how fast your steps are. Purposeful walking that raises your heart rate is best measured with a heart rate monitor. I only log purposeful walking.

Find a balance that you can sustain. I couldn't stick with 1200, plus I'm closer to goal and a large deficit doesn't support lean muscle efficiently (over 50 and can't afford to lose more muscle).
