Your natural weight will level when you are content in your sobriety, along with a balanced diet and exercise at least 3x/wk. Expect your natural weight to occur around the 6 month mark of sobriety. If at that point you want to lose more, or tone up etc... then you will need to create a plan to do so, but dont bother with that just yet. Concentrate on yoyr health and well being in the early days... keep things as easy and stress free as possible.
I lost about 30lbs (from 205 to 175, 6' male) in the first year, and have maintained the same weight now for about a year. That weight loss was basically due to absence of alcohol, b/c my diet has remained the same.
All else being equal you will lose weight for sure, it's inevitable.
