What are some good diets? not meal replacement!!!?

I have been looking for some healthy diets and I need some more options. I already tried low carb and it worked but I realized the problem with that is you are cutting out a food group so you gain most of it back. I tried calorie counting but I always seem to fail. What are some good diets? Does the Diet Solution book work? or maybe the Amen Solution? anyone ever tried them.. did they work? thanks(:
