Confused about calorie goal
I am going to embarrassingly post my stats in hope for some help. I am throughly confused after reading through the message boards and trying to decide if I have my calorie goals set correctly. I, like most, just entered my stats in MFP and said I wanted to lose 2lbs per week and off I went. MFP has me calculated at 1200 cal/day. Then when I was reading I saw some posting about another calculator and when I did that one it had be at 1500-1600 (I can't remember the exact number). There was lots of talk about not eating enough calories and not losing and of course we all know if you eat too many then you also don't lose. I tend to notice I stall a lot and I know I make bad food choices (eating 200 calories of cake on my birthday instead of fruit) but whatever. I am still new at this and do my best most of the time (I admit I have issues like everyone) but I just want to really try to have my goals set so that I succeed. Anyway, I apprecaite any help or advice anyone has. Thank you in advance. Now for the embarrassing part:
34 year old female
189lbs (down from 218)
Work 8 hours at a desk job basically at my desk the entire day
Do couch 2 5k 3 times per week
Walk 2 miles 3 times per week (on the days I don't do C25K)
Have a 16month old son
Is that enough info for any advice?
