BMR??

I've been eating just under my BMR, based on my TDEE deficit and it has been working nicely so far.

I'm sure this has been posted before, but I am new to the site so I figured I would ask. My BMR is 1665 calories a day according to the calculator on this site - so does that mean I should be eating at least that many calories each day? :ohwell:

No, your BMR is just what your body needs to survive everyday, if you didn't get out of bed. It doesn't account for regular daily activity, your job, and your exercise - that is TDEE, total daily energy expenditure. It is this number you need to eat under. Many people will recommend not eating below your BMR.
