My conso was or is 70 days but I also think it will depend on a lot of factors. Why you had gained the weight, what your eating is actually like and if you have taken on board a change in eating. I think for me, because I have an underactive thyroid and the weight crept up and up but I took my calories down and down it was different for me. My thyroid condition is finally under control, the weight off and I am more active by default.
I see you are over half way there now, you must be feeling really different now.
