yes weightwatchers is calorie control but you can eat any foods you like all day as long as u stick to your calories. slimming world is a healthy eatin plan where you can eat as much of certain foods in a week as you want and you have sins for alcohol, junk food etc. i have lost weight on both so they both work it just depends on what suits you as a dieter. slimming world you can carry on doing whilst pregnant, weightwatchers you cant because it restricts calories. i am doin slimming world at mo cus im PG. with weightwatchers you tend to eat less especially if u eat what you normally eat so sometimes you can be left hungary at night but with slimming world it only really works if u eat alot of the free foods as the more you eat the more weight you will lose. hope this helped hun. xxxx
