Whether you're looking for a diet to lose weight or just to get healthier, here is a list of the best diet plans from US News and World Report.

This year they've added a new list -- the easiest-to-follow diets, which got points for convenience, taste aand how full you feel when you're on it. Here's how they rank:

#5 --Volumetrics

#4 -- SlimFast

#3 -- The Mediterranean Diet

#2 -- Jenny Craig

and the #1 diet:

Weight Watchers

Research also shows it's not what you eat, but how many calories that really counts when it comes to weight loss. And a diet combined with exercise can help burn those calories.

Have you tried any diets? If so, what worked and didn't work for you? Or what did you love/hate about the diets you tried?
