I'm eating more and I'm bloated PLEASE READ AND HELP!?

So the last two days I promised myself I would eat more and see how it went. I don't eat a lot on a regular occasion, usually only 1,200 calories a day and this has been going on for almost two years now only last year it was more like 500 calories everyday. You see the issue. So I promised myself that I would do this because honestly I need to be eating more and I think such a restrictive diet is making me hold onto belly fat. Anyway so I've been eating more (1,400 about) and holy crap I am soo bloated! I'm also really hungry which is weird! Is this just my body adjusting or is this what will always happen? Should I go back to 1,200?
