It ain't hard. Just takes you getting into the mindset. It's basically:
All plans: unlimited fresh/frozen fruit and non starchy veg
Green unlimited healthy carbs, so your dry pasta (fresh pasta has oil), beans, rice, cous cous, starchy veg ie spuds, peas etc
Red: unlimited lean, healthy meats like chicken with skin off, fish, meat with fat cut off
Extra easy: all free food on red and green is unlimited, but try to make a third of each meal fruit/veg to limit calories
Healthy extras: those foods which are good for you but in large quantities can put on weight. You get a healthy extra A each day for calcium ( measured milk or cheese) and a healthy extra B each day for fibre and vitamins (wholemeal bread, cereal, dried fruit etc). On green and red you get 2 of each instead of one.
All plans: 5-15 syns a day. For those treats or extras you can't live without. Basically either for extra healthy foods that put on weight, like nuts and cereal. Or for food without much nutrition like chocolate, ice-cream, gravy etc.
It's the least amount of weighing/counting I've ever had to do on a diet.
I tried the starve-myself-till-I'm-thin diet once. Lost weight, maintained for about a year then put it all back on plus 2 extra stone. And I was miserable! This plan's great!
