My wife joined WW five years ago, just after we got married (the wedding photos are NOT on public display). She didn't do the meetings, but the 'at home' option. As I was doing all the shopping and cooking at the time, I was going to have to be involved if it was going to work. We then bought some scales. 17 stone
Before the end of the year I was down to around 11 stone (never below that and usually about 11-7).
I'm now just under 12 stone. We didn't usually feel hungry during the experience (obviously there were one or two occasions which were difficult, but usually no problem).
Suggestion -- budget the treats FIRST! (in my case a beer allowance).
Obviously worked for us. My only cycling during that period was the 2.85 miles each way to work, four days a week. I also swam once or maybe twice a week.
Losing that much weight had some problems -- several old friends have failed to recognise me! But over all I'd recommend WW (and trying to be a sensible weight)
