3 ST by end October - Is it Possible ?

I want to lose 3 stone by end October. Is this possible on WW ? I am currently doing the Cambridge Diet, but want to start eating but the only thing keeping me on CD is the fact that I know I will be able to get to 16st and lower by October, but not sure if I could do that on WW ? Can I have everybodys opinion on this please ?

theres 20 weeks until we hit early october, so realistically, you could lose 20-40lbs by then on WW as the diet promises a healthy weight loss of 1-2lbs a week x

You very possibly could, men often lose a bit faster. Even if you didnt, you wouldnt be a kick in the pants off it
