TV and radio ads for various companies tell you their food is what you need to lose weight. And of course, their food comes at a hefty price. Do the math: Depending on which diet plan you choose and which specific foods you buy, you could pay anywhere from $300 to $700 per month. Plus, if you have a family, not only are you paying for and preparing this special diet food, you’re also still buying groceries and cooking meals for the rest of the family. Not much of a bargain there. Luckily, those diet plans aren’t the only game in town. There are countless diet books on the market. You could spend a pretty penny at the bookstore, too, if you decide to check out each and every one. Fortunately for you, we’ve surveyed some of the best dietitians in the country and they’ve come up with a list of the 10 best diet books. See the full list on our sister site, Living on the Cheap. See which one suits your style best.
