You should be, actually. The correct answer is NONE! Diets are normally temporary solutions at best, and most people gain the weight back when they go off the diet. In some cases they gain back even more than they lost. This happens for a reason - your body goes into starvation mode, and ends up storing fat instead of burning it. Aside from that it just makes a person crabby!
Instead of using the term diet (a four letter word in my book), think healthy eating instead. Take some time to learn what foods are good for you and what they do for your body. If you are more aware of why you're eating something, and why you shouldn't eat other things, you will eventually be able to make a smarter choice every time. Reading labels is KEY. First rule of thumb: If you can't pronounce it, there's a pretty good chance you shouldn't be ingesting it!
