WW does work but I got to a point I was sick of forking out money each week just to weigh in I couldnt stay for the meetings as I have a family and it was too hard.
My DH is doing Rapid loss shakes and in 3 weeks has lost 11 kilos it works. There is a new healty eating program called the swapit program where you swap something bad for something good. Look in the end all things work and if you are joining a gym then half your battle is over. I had a eating plan devised by my personal trainer just focused on healthy eating 5 small meals a day having carbs for breaky and lunch and a healthy dinner. Cutting out starchy food like white breads rice potatoes peas etc.Just cutting down portion sizes and limit bad foods and exercise and plenty of water. When I was training I went from 128kgs to 109kgs it does work my trainer used to say that alot of his clients like to have a beer etc so they train and eat pure during the week and this allows then at weekends to splurge a little. If you deprive yourself totally you will fail really quickly as I found out and also your mind has to be on the ball to. I hope you find what works for you and good luck in your journey.
