Myth or Fact: Myth

It's not when you eat, it's what (and how much) you eat. The reason some diets suggest you close the kitchen after enjoying the early-bird special is that people have a tendency to overeat at night, especially if they have skipped a meal during the day. "If you are finding yourself bingeing at night, chances are you are not eating anywhere near enough good calories during the day," says Borden.

Capitalize on the facts: You can eat at night, just watch what's on the menu. Borden recommends a light meal or a protein shake with water, berries and some fat: "I love UDO's OIL 3, 6, 9 blend. It's a mix of wonderful omega and nut oils that will help satiate your hunger. Not to mention help your skin, lean muscle tissue and digestion." Can't live in a world where nighttime doesn't include a bowl of something sweet or a bag of salty snacks? Try substituting fat-free yogurt or whole grain cereals with skim milk for the ice cream, and baked chips and salsa or one of those 100-calorie snack packs of crackers for the cheese doodles. Just don't over-indulge.

Mindless eating is a real danger of nighttime eating; so try not to eat in front of the TV and be wary of food-goggling (over-eating under the influence of cocktails).

Myth or Fact: Myth

You gain weight when you consume more calories than your body burns. And yet, not all calories are the same. It's really the good carb/bad carb distinction. "Bad carbohydrates (refined simple sugars) are rapidly digested and absorbed into the bloodstream," celebrity nutritionist Paula Simpson explains. "If there is a high concentration of blood sugars (hyperglycemia), then [the excess sugars] can be stored as fat." The fiber in good carbohydrates helps slow down the rate of digestion, controlling blood sugar levels, which results in a longer window of time during which the body can burn the calories from those good carbohydrates before the excess is stored as fat.

Capitalize on the facts: Eat more complex carbohydrates -- fruits, vegetables and whole grains -- and try to avoid simple sugars like candy and soda and any of the "white" foods like regular pasta, potatoes and bread. Need another reason to choose good carbs over bad? Simpson points out that the fluctuations in blood sugar levels caused by the rapid digestion of simple carbohydrates can make you feel tired and can mess with your appetite control regulation. That can't be good for those of us who already feel like our appetites are out of control.

Next: Drink up

Myth or Fact: Fact

A study conducted at Penn State University demonstrated that eating foods with a high water content increases one's sense of fullness. Interestingly, drinking water on its own has not been shown to have the same impact. Evidently, water is emptied out of your stomach more quickly than water incorporated into foods you eat, so it doesn't trigger any of the body cues that tell your brain you are full.

Capitalize on the facts: Have a cup of broth-based (no cream!) soup as an appetizer or before you go out. And, if you are still drinking high-calorie juices or sodas, replace them with water. That glass of water may not make you feel more full, but the calories it saves could help the weight come off. And -- bonus -- because water flushes toxins from your body and carries nutrients to your cells, it helps to reduce skin breakouts and minimize under-eye circles.

Next: Calling all carnivores

Myth or Fact: Myth

You don't have to swear off red meat. Red meat, in moderation, is a great source of protein and iron.

Capitalize on the facts: Choose lean cuts of meat -- sirloin tip, flank steak, extra lean ground beef -- and then trim away all visible fat. And portion control is key. "Try to cut down your red meat intake to once every week and a half," Borden advises. "Your portion should be approximately the size of your palm and the thickness of your palm � not your boyfriend's palm or Shaquille O'Neal's palm!"

Myth or Fact: Myth

This was a gimme, right? Ephedra ring any bells? Just because you can buy something in a health food store doesn't mean it's healthy. Unless and until a product's claims have been evaluated by the FDA, you should be skeptical. And, in any event, it's worth consulting a physician before taking any drugs.

Capitalize on the facts: While there is no magic pill, there are FDA-approved diet drugs and appetite suppressants (over-the-counter and prescription) that, when taken in conjunction with a reduced calorie diet and an exercise plan, can help you lose weight. One example is Alli, an over-the-counter medication approved by the FDA, which blocks fat absorption by about 25 percent. But Alli, like all weight loss drugs, is not recommended or appropriate for all dieters. Again, before taking any drug, you should talk to your doctor.
