After researching the Volumetrics plan, I'm convinced it's among the best eating strategies yet. So does Consumer Reports.

Notice that the word "diet" is not mentioned. "Diet" implies temporary while "eating strategies" and another commonly used phrase "eating plan" implies permanent changes. The book "The Volumetrics Eating Plan" by Barbara Rolls, who is a professor in the department of nutritional sciences at Pennsylvania State University, is worth a read for anyone looking to take control of their nutrition for the long term rather than just lose a few pounds for the summer.

The runner-up is the review was the Weight Watchers International Inc. (NYSE: WTW) diet plan (I'm a fan of this one) and Jenny Craig also came in a very close third.

The rest? Well, do your homework and see if there are solid tracts of science behind whatever diet plan you choose -- and don't fall for the marketing hype or baseless celebrity endorsements.

It's easy to do.

From the recent Atkins Diet craze to the newest "Best Life Diet" that counts Oprah Winfrey as an endorser, there are many plans making claims to be the best.

As Consumer Reports shows, very few are worth the bother.
