You've done some pretty harsh things to your body (Slim-fast, clensing, binging, etc...). You are going to need to give your body some time before it trusts that you aren't up to something else and is willing to relax and start letting go of those pounds. 1,400 calories a day is about the minimum I'd recommend you eat. You might actually lose better between 1,600 and 1,800 a day. What I usually recommend is at least 10-12 times your goal weight (that's a minimum, not a maximum). Sounds strange, but if your body isn't getting enough of what it needs, it will hang on to everything coming in.
