As someone who has done FF, and passed it on to others, I think it's important that people understand that it's not a life-threatening, unhealthy plan that will make you seriously ill if you do it without your consultant recommending it.
It's simply the SW plan, but with portion control and a healthy limit on snacking. It's three meals a day, plus snacks, and includes things like lots of bread, ready meals, veg, fruit and salad.
It's a lot less food than a lot of people are used to, and if you still have a lot of weight to lose, it is probably too restrictive and not neccesary. But if you're plateauing with not much weight less to lose, it's a great way to kick start your body into losing sensibly again.
Just to make a point, there was a guy at our class who still has about 5 stone to lose, but he was scared of putting weight back on so had stopped eating properly and as a result had stopped losing weight... The consultant put him on FF for a week and he said he really struggled to eat all the food on the plan as it was a lot for him (he was 25st when he started!) to eat. He lost 3lb that week, but my point is that it was way more than he usually ate - the Fast Forward plan is not a lettuce leaf and a glass of water, and if you feel you need a boost, your consultant will give you the plan to follow....
Good luck everyone, the SW tools are there for a reason!!
