Could food be ruining your mood?

One of the top nutritionists says not only can your diet be killing your buzz, it could be harmful to your health.

Susan Kleiner’s new book, “The Good Mood Diet: Feeling Great While You Lose Weight,” is full of tips to help you eat your way to happiness.

She says while the rest of the diet world is focused on “medieval torture,” she has ways for you to feed your brain. Instead of choosing diet techniques that will make you depressed, Susan offers strategies for not only losing weight but keeping it off.
