Thanks for your kind words, Libby, Epixi and Jenn.
Libby, if you are up after one day at 1200 cals that is water weight. There's no way you could gain there (short or no lol). It is hard to know the right number of calories to eat to lose and everyone is different. It's kinda trial and error. But consistently eating under 1000 cals is likely to backfire.
It's wonderful about the walking. You will feel so much better. You may need to boost your metabolism a bit and the best way to do that is add some muscle.
How many days have you been cutting calories? How much do you expect to lose? Are you expecting to lose everyday? For me, after a quick initial loss, I slowed down to 2-4 pounds a month. It was either be ok with that or do something drastic. I'm in it for the long haul so I guess I'm ok with that.
