Hi, am new to MN thought i'd chip in that i joined the dreaded WeightWatchers. 8weeks ago now and i've lost a stone , and i'm breastfeeding.
I find it works because it looks at healthy eating and exercise as a whole, and it is realistic - no foods are forbidden. It can be a pfaff working out the points but for me it's worth it... In theory it's finding a healthy eating plan for life - if it's a diet - and most of them work. You have to be prepared to stick to it once at your goal or it just piles back on (speaking from experience). I've got another 6 stone to loose (anyway!) so wish me luck and i wish you all luck too.
