1. Every diet soft drink consumed each day could increase your risk of being overweight by 65 percent, according to a study presented at the American Dietetic Association. Other research suggests that artificial sweeteners may actually stimulate appetite, causing you to overeat.
2. A recent Japanese study found that people who drank a daily 11-ounce bottle of green tea lost 5.3 pounds after three months, while those who drank regular tea lost only 2.9 pounds.
3. Eating three servings of grapefruit a day (either half of a whole one or a cup of juice) for 12 weeks could help you lose just over three pounds, according to a recent study. "It helped lower insulin levels, which can contribute to weight loss by reducing appetite and encouraging fat burning," explains study author Ken Fujioka, MD, director of nutrition and metabolic research at Scripps Clinic in Del Mar, California.
4. A University of Washington study found that doubling up on protein could help you eat less without feeling hungry. "Protein may make your brain more sensitive to leptin, a hormone that helps you feel full," says study author Scott Weigle, MD, a professor of endocrinology at the University of Washington School of Medicine. Make sure at least a third of each meal and snack is a source of lean protein.
5. People who sleep seven to eight hours per night are leaner than those who get only five or six hours, according to research from Laval University in Quebec. "When you're sleep-deprived, your body produces more stress hormones, which may increase your appetite," explains Michael Breus, PhD, cofounder of Sound Sleep Solutions in Atlanta. Having trouble nodding off? Consider hitting the treadmill before, not after, work: One study done at Seattle's Fred Hutchinson Cancer Research Center found that women who exercised in the a.m. fell asleep faster at night than those who did a p.m. workout.
6. "Instead of refined and processed white foods, aim to have whole-grain starches such as brown rice, whole wheat pasta, whole wheat breads and bran cereals," says Blatner. For the most part, the browner the food, the higher the fiber, which spells w-e-i-g-h-t l-o-s-s. According to a 2005 research review, increasing consumption of dietary fiber is critical to losing weight, because it helps you feel fuller and decreases absorption of calories from other food sources.
7. Successful dieters eat out fewer than two and a half meals per week on average, according to the National Weight Control Registry. If you're strapped for time, simply nuke a frozen dinner. A recent University of Illinois study found that dieters who followed a meal program that included two frozen entrees a day lost more weight than those who followed the USDA Food Guide pyramid. "Frozen dinners serve as a form of portion control, so you don't overeat," explains Dr. Hensrud. Look for entrees with fewer than 400 calories each: Lean Cuisine, Weight Watchers, and Uncle Ben's Rice Bowls are all good choices.
8. "I've had clients come in complaining that they can't lose weight, but then I find out that they're taking in hundreds of calories while preparing dinner," says Blatner. "Every little 'taste' counts!" Her tip? Sip a Low Sodium V8 juice. "It's only 50 calories per serving, but it will keep you feeling satisfied and stave off hunger pains so you're less inclined to snack," she explains. (The new Calcium Enriched V8 makes it easier to protect your bones, but that's another story!) Hate V8? Chew gum to keep your mouth occupied.
9. Feel the Heat
"When food is warm, its molecules move around faster, which means it will have a stronger smell," explains Alan Hirsch, MD, director of the Smell and Taste Treatment and Research Foundation in Chicago. The result: The aroma affects the satiety center in your brain, leading you to think that you've eaten more than you have, so you feel full faster. In addition, if your food is hot, you'll be forced to eat it more slowly, which will give your stomach time to signal to your brain that it's full.
10. Brush your teeth or rinse your mouth right after you have a meal or a snack to quell the urge to keep nibbling. "It's both a physical and a psychological signal to your body that you're done eating," says Blatner.
11. "One reason women overeat is that they don't hit their food craving right on the head -- they keep bingeing until they're finally satisfied," explains Blatner. Ask yourself what you really want: Salty? Sweet? Smooth? Crunchy? "Food cravings can be broken down into four categories," says Blatner. "If you are craving sweet and crunchy, try a mini bag of popcorn mixed with a little bit of artificial sweetener or even sugar. If you want sweet and creamy, opt for a light vanilla yogurt. If you're thinking about something salty and smooth, try a couple of pieces of low-fat string cheese; if you really want salty and crunchy, try a handful of dry-roasted nuts or soy nuts."
12. K.I.S.S. (Keep it Simple, Sweetie!)
People who eat a variety of foods, even low-fat ones, are more likely to have trouble keeping weight off than those who rely on a few diet staples, according to a National Weight Control Registry study published last May. "When people have a wide range of foods in front of them, they generally eat more," explains study author Holly Raynor, PhD, RD, an assistant professor of psychiatry and human behavior at Brown Medical School/the Miriam Hospital. The study showed that the most successful weight losers consistently consume just three to five staples from each food group, switching them around occasionally to prevent boredom.
13. Distract Your Taste Buds
Visions of Godiva flooding your head? Before you rush out to buy a box, try deflecting your attention. New research from Flinders University in Adelaide, Australia, has found that the more vivid your mental image of a particular food, the more likely you are to crave it. But there's plenty you can do to tone down those visual cues. Researchers found that randomly flicking through images on a computer screen or, to a lesser extent, listening to a speech in a foreign language, was enough to distract students from their food cravings. Anything that engages both your eyes and your mind -- like playing Sudoku -- should help, say researchers.
