I would just say, keep at it. Allow yourself treats. Are you deffo eating 1200?
From what you have written, that sounds under to me. I keep going under and it really backfires.
I was the same, at the start it took me 2 weeks to lose a measly pound.
Have a slice of bread i have one a day, do have milk with your cereal.
Make sure you eat your proteins, and don't be worried if you go over a bit with those.
Lots of water, i hate it but i now keep a mug by the sink and i make sure i drink some every time i go to that sink!! which seems to be alot of times.
Ryvitas are great, lots of different types out there. I also make sure i eat a few brazil nuts a day.
