I eat no more than around 1200 a day now, 3 meals, no snacks. Although when I was pregnant I did aim for about 1800. I'd recommend that, because its tough going from eating lost and lots of calories to such a low amount!
I aim for each meal to be around 300-400 calories.
Tiaratara, sorry to hear about your feet. I don't know about your area, but here people can self-refer to NHS physiotherapy so that might be something for you to look into. If you can't self refer, I'm sure your GP would refer you. You'll still lose weight despite not being able to exercise, I didn't exercise at all whilst pregnant and I still lost a lot of weight xxx
