1200 is more on the low end if I'm not feeling particularly hungry, I typically eat between 1200-1500 calories a day so that on the occasions when I want to treat myself and eat out and have something really calorie dense I don't have to worry about it or if at the end of the day I'm peckish and I want to have like a small snack I can have it without worrying. I've been eating like this and essentially maintaining my weight so it works for me, granted I think I might have a slightly damaged metabolism as I suffered from an ED between the ages of 14-17.
