Sounds like WW is for you. It is points based but that is a shorthand and (IMO) better version of calorie counting because it takes into account total fat, fibre, carbs and protein of a food to get the points value. With WW you are free to eat what you choose so it is a "real life" diet (not like a shake-based or restrictive diet one where you add or cut out things while "on" the diet).

WW works. You get support from the meetings (a CRITICAL part of the program) and lifestyle change is an essential thing with it too. You have to keep an eye on fruit/veg, water intake, exercise - the works. It rocks!
I can totally vouch for this! Before I was married I lost 22kg in 6 months on WW and it is probably the best 'diet' around for teaching you how to *think* about what you put in your mouth instead of being *told* what to put in it. You only really learn by having to work it out yourself - calorie king is good for this as well. It also allows you to keep cooking the food you always cook in your home and be aware of what points all the ingredients are and make modifications etc. Other prescribed diets are probably OK, but how many times would you make a warm tuna and tossed green salad with balsamic dressing for your entire family to eat kwim? I will do it online for a little while and then drop off and the problem is not having a meeting to go to to keep me honest. Not that I 'cheat' when I'm on it, but knowing you have a weekly weigh in gives you something to strive for.
