I'm now 11st 8lbs and have been below 75kg for 6 weeks. My current target is 11st 6lbs (160 lbs) and to hold at or below 75kg for 3 months.
Ideally I would like to get below the psychological barrier of 25 BMI (73 kg, 160lbs) and stay there for a while, if not indefinitely!
I have upped the calorie intake quite a bit now and I am still maintaining. If I have a bit of a binge, I know exactly how to bring the weight down, usually within a day or two.
