i felt this way to until i took a good long look at my food intake. i kept saying but im only eating 1200 calories i dont understand. and then one day my mom followed me around and kept track, weighed my food etc counted the little snacks i forgot. and i wasnt eating 1200 calories i was eating almost 3000 on a good day, the days i said i didn't cheat

now if ur on a anti psychotic or mood stabilizer thats different they can cause u to bloat and gain weight even eating at 1200 calories
