Is 1200 calories not enough

lnicker

I need advise on how many calories I should be eating. First of all, I have to work at keeping weight off and worked really hard to lose 60 pounds prior to now and my fitness pal.

MFP tells me I need 1200 net calories. My body seems to starve at that amount so I upped it to 1400 net. I am also training for a half marathon so I am eating a lot of extra calories to make up the net calories. I am putting on weight. I know a lot of people say this could be muscle and I do think some of it is that, but my pants keep getting tighter and my stomach seems to be getting larger. And I know when training that you shouldn't worry about not losing weight, but for someone who has struggled my whole life, having my pants getting tighter on me is really hard for me. Now I wonder should I cut back to 1200 again and make sure I eat back all the exercise calories, or should I be eating even more? I can't seem to find my right number. Any help would be appreciated.
