Love bread, pasta, and potatoes but fear they'll go straight to your hips? Sprinkle them with a little vinegar. "In most instances, when we eat high-carb foods like bread, the amount of glucose in our blood rises rapidly. But very quickly it plummets, triggering feelings of hunger that cause us to eat even more," says Carol S. Johnston, PhD, RD, director of the Nutrition Program at Arizona State University in Mesa.
"The good news is that vinegar moderates that spike in glucose, so you feel full longer," Johnston explains. In fact, in a recent study people who consumed 4 teaspoons of apple-cider vinegar along with some bagels and juice ate 200 fewer calories throughout the entire day than those who feasted on the exact same meal minus the vinegar.
Tip: Take small steps to cut 200 calories a day from your diet and you'll lose 21 pounds in a year.
