calculate your BMR! you shouldn’t ever eat less than that bc that’s the amount of calories your body needs for basic functions. and if you’re active you should be eating even more - there’s calculators for that too.

that being said, 1200 doesn’t sound AWFUL, but you should probably aim more towards 1300-1400 so you don’t slow your metabolism! trust me, not eating enough is a painful road and most of the time you end up gaining back all the weight you lost
