help needed

Hi everyone i have been doing ww but have only managed to loose about 3 pounds in 6-8 weeks i would really like to try cs do u think u can lose more on this than the likes of ww? also how much stuff do u need to last u for 1 week like how many shakes ect?

It depends how much variation you want, eg. shakes, bars, soups etc. I had 2 shakes a day and they come in a box of 14 which would last a week.
