While I adjust to the heart meds I have re-set my maintenance level to "not very active" . For my size/age, MFP says 1470 calories. Not a lot, but ok.
Surprisingly though, I weighed myself this morning and in any case I appear to be lighter than I thought. 9st 8.5 lbs. So it will be interesting to see what 1470 cals does with my "beta-blocked metabolism" !
