ET's own Kevin Frazier gets a sneak peek inside Oprah's fridge -- and some serious tips from her health and fitness super coach on how to whip yourself into shape for the summer!

Kevin visited Oprah's Montecito Mansion -- nicknamed Oprah's Hearst Castle -- to get inspired by Bob Greene, who shares the six foods he wants to pull off your table for a better body.

"Get rid of them; don't eat them or limit them," says Bob. "We eat so many calories due to stress, boredom -- a void in your life."

"The first one I pull off the table, only temporarily, because it slows your metabolism, is alcohol," says Bob. "So if you love your wine with dinner, pull it off for a month or two. Substitute with a healthy beverage -- water would be my first choice."

Another thing to abandon is soda: "If you substitute one sugary beverage every day with water, that's 38 pounds of calories a year that was just eliminated," says Bob.

Other foods to remove from the table? Fried food, white bread, foods with trans fat, and high fat dairy.

"Most people think the secret is in the foods you eat -- and they're very important -- but the truth of the matter is most people are looking to comfort themselves," explains Bob. "It's not that you're physically hungry that makes you go to the refrigerator too often, it's the stress in your life; worrying about your work situation, do you have relationships that are valued and fulfilling? That's the key really. Misusing food, we do it for a reason -- and clearing up those issues in your life is the key to your success."
