When it comes to weight loss, there are a lot of gimmicks out there. But That's Fit readers know this: Gimmicks never work, and sometimes they can leave you with more weight to lose than when you started. The other day, however, a friend told me about an idea that sounds gimmick-y, but is actually just a new way of looking at solid, time-tested advice.

It's called the 5 and 30 plan. The idea is easy -- eat a minimum of five fruits and vegetables a day and get 30 minutes of moderate exercise. Essentially, the plan reduces calories, increases fiber, improves nutrition and ensures daily physical activity. But at the same time, it sounds pretty simple.

It's not a diet, it's a way of life. And this week, I'm going to try it on for size.
