Research shows that simply shifting around the groceries in your kitchen can actually retrain your brain, helping you crave healthy foods instead of junk, says Larrian Gillespie, M.D., author of The Goddess Diet. The top shelf of your fridge is a good place to start. This eye-level area is prime refrigerator real estate. Stock it with healthy and low-cal beverages: skim milk, 100% fruit and veggie juices (no sugar added) and calorie-free soft drinks. Why? "Opting for low-cal beverages is a simple way to shave calories out of your diet," says Dr. Gillespie. "Plus, staying well hydrated naturally helps curb appetite." Use these slimming thirst-quenchers to cut just two sugary sodas out of your daily diet and University of Minnesota researchers say you can shed up to 33 pounds this year.
