I have done both WW and SW.
I found WW to be a lot easier, you could just put ready meals in the microwave. And because I like lots of 'nice' snacks (ie not fruit!!!!!!) It worked for me. You could get lovely choccie cookies, still have chip shop chips etc!! But I found I didn't eat healthy and substituted lots of meals for junk food!!
Why have a piece of fruit when you could have a cookie instead!!
Though I lost 4 and a half stone on WW, quite quickly.
But.........I am a comfort eater, needed comforting and put 2st back on!!! I am now having a go of SW!!
On SW you can't have much Chocolate, wine etc, chip shops dinners are out unless you save days of sins! But.....
You can have lots of free food, inc lots of fruit. For me, I find this a lot healthier. And can snack whenever on free food, although you do tend you have a dislike for pasta n sauces after a while!!
Hope that has helped a little!!
Do you have a friend that goes anywhere? It is always a good incentive to go with somebody so you HAVE to go each week!!!
Good luck
