I've been on optifast for a year.. I've been seeing a dietician in Frankston Private - Sharon Marks.
If you stick with it and do replace 3 a day, in a couple of months you will be shocked as hell how much you can lose. And that was with NO.. NIL exercise...
Last 3 mths I've been on 1 a day and not being very careful with what I eat, and it shows..
Now trying to get my act together and stick with 3 a day
Dropping sugar and sugary drinks will also help massively, but I cant drink just plain water day in day out, its just too bland for me..
