Bad Eating Habit: You’re a serious snacker.

The Fallout: You may end up overeating. A healthy snack or two between meals is fine. They can keep blood sugar steady as well as allow you to rack up more servings of fruits and vegetables. “It’s when you snack in place of eating real meals that you’re more likely to lose track of how much you’re eating,” says Tara Gidus, R.D., an Orlando, Florida–based spokesperson for the American Dietetic Association. Of course, what you eat matters, too. Typical snack foods (chips, cookies, pretzels) aren’t that nutritious or satisfying, so it’s easy to overdo them.

The Fix: To keep your energy up and hunger at bay, allow yourself two snacks a day of 100 to 300 calories each. “Rather than a cookie or a candy bar, opt for something that feels like real food — half of a small sandwich, whole-grain crackers with cheese, a handful of nuts, baby carrots with hummus, or yogurt sprinkled with cereal,” says Gidus.

Bad Eating Habit: You’re a speed-eater.

The Fallout: Gulping food may set you up for stomach troubles. “You take in excess air, which can lead to bloating,” says Leslie Bonci, R.D., director of sports nutrition at the University of Pittsburgh Medical Center. You also might not be chewing well. Saliva begins to break food down, and too little time in the mouth leaves more work for the rest of the digestive tract. This may contribute to indigestion, says Ellie Krieger, R.D., host of the Food Network’s Healthy Appetite. Finally, speed-eating doesn’t give the brain time to catch up to the stomach; it needs at least 20 minutes to get the message that your stomach is full. A recent study found that women who ate a meal in 30 minutes ate 10 percent fewer calories compared with those who wolfed one down in barely 10.

The Fix: Try to slow down. Avoid finger foods, and instead choose items you have to put on a plate and eat with utensils, such as stir-fries and salads. Pause often, and drink water throughout meals.
