Eat chocolate to slim down? Yes, it's true, says a study in the American Journal of Clinical Nutrition. In fact, snacking on two small squares a day may help curb a hormone that triggers belly flab. Read on for more tips and tricks from celebs and the nutritionists and trainers who help them stay slim -- and drop pounds fast.
Tea Up to Trim Down
Green tea = hot-body brew! Those who sipped it daily shed 3 pounds in three months, according to an American Journal of Clinical Nutrition study. "Tea's catechins can trigger calorie burn," says dietitian Keri Glassman, who has designed meal plans for Sofia Vergara.
Be a Cocoa Buff
A good excuse to eat chocolate: People who do so have less belly fat, says a Nutrition study. Researchers think antioxidant-rich dark chocolate may curb cortisol, a hormone that triggers abs flab. Advises Heidi Klum's nutritionist Oz Garcia: Snack on two squares a day.
Veg Out More
Vegetarians, who typically have less fat in their diets, lost about 5 more pounds than omnivores in two months in a University of South Carolina study. For a similar effect, Glassman, cohost of HLN's Cook Your Ass Off, suggests going veggie one day a week and eating lean protein (poultry, fish) the other days.
Take a Stand
According to a study from the U.K.'s University of Chester, standing an extra three hours a day can burn 720 calories a week -- or help you drop 8 pounds a year! Suggests Kelly Rowland's trainer, Jeannette Jenkins: "Cook at home rather than eating out and stand while on calls."
Pack in Protein
Start your day with a high-protein breakfast (a Greek yogurt parfait is a great choice) and you can shave 120 calories off lunch, suggests University of Missouri research. Experts say the protein helps release appetite-curbing hormones.
Phone It Thin
To dial up your willpower, use a healthy-themed picture as your cellphone wallpaper. People who looked at an image of fruit before a meal ate 106 fewer calories in an Appetite study. The theory: The photo reminds dieters of their goals.
Get on the Chew-Chew
People who took twice as many bites of their food consumed 112 fewer calories at each meal, says a study from Iowa State University. Explains one of the researchers, Dr. James Hollis: "Chewing affects the part of our brain linked to satiety."
