What makes Greek yogurt a delicious tool for weight loss is its protein content. It has twice as much as other yogurts. "Protein takes longer to leave the stomach," says sports nutritionist Leslie Bonci, MPH, RD. "That keeps you satisfied longer." As a bonus, Bonci tells WebMD, the body burns more calories digesting protein than carbs. Non-fat, low-fat, and low-sugar types keep a slim profile.
Quinoa (pronounced keen-wa) is a nutritional all-star that belongs in your weight loss plan. This whole grain has 8 grams of hunger-busting protein and 5 grams of fiber in one cup, plus it's as easy to cook as rice. It's also packed with nutrients such as iron, zinc, selenium, and vitamin E. For a quick and interesting dinner, mix in some vegetables, nuts, or lean protein.
Studies suggest cinnamon may have a stabilizing effect on blood sugar levels. This could curtail appetite, particularly in people with type 2 diabetes, Bonci says. Nearly everyone can benefit from cinnamon in its traditional role. Stir some into your coffee, tea, or yogurt to add sweetness without adding calories.
Hot peppers contain a flavorless compound called capsaicin. It's more plentiful in spicy habaneros, but also occurs in jalapeños. This compound appears to curb appetite and speed up the metabolism slightly, but only for a short time. Bonci doubts that this has a significant impact on weight loss. But, she says, people tend to eat less when their food is spicy.
Several studies suggest green tea may promote weight loss by stimulating the body to burn abdominal fat. Green tea contains catechins, a type of phytochemical that may briefly affect the metabolism. To get the most benefit, you may need to drink green tea several times a day. Bonci recommends taking your tea hot, because it takes longer to drink, slowing your calorie intake and providing a soothing, mindful experience.
While grapefruit doesn't have any magical fat-burning properties, it can help dieters feel full with fewer calories. Bonci attributes this to the plentiful amounts of soluble fiber, which take longer to digest. Having half a grapefruit or a glass of grapefruit juice before a meal may help fill you up, so you eat fewer calories during the meal.
Foods that are high in water content take up more room in the gut, Bonci says. This signals the body that you've had enough to eat and leaves less room for other foods. Many raw fruits and vegetables are chock-full of water and nutrients, but low in calories. Watermelon is a great example. It's a rich source of the antioxidant lycopene and adds some vitamins A and C to your day, too.
Pears and Apples
Pears and apples are also high in water content. Eat them with the peels for extra fiber, which will keep you full longer. Bonci recommends whole fruits rather than fruit juice. Not only do you get more fiber, you have to chew the fruits. This takes longer and requires some exertion. You actually burn a few calories chewing, as opposed to gulping down a smoothie.
Grapes vs. Raisins
The value of water content becomes clear when you look at two cups of grapes vs. ¼ cup of raisins. Either choice has a little more than 100 calories, but the larger portion of grapes is likely to feel more satisfying. Still, Bonci says, dried fruit has an interesting texture. When used sparingly, a few raisins or dried cranberries can make a salad more appealing.
Like other fruits, berries are high in water and fiber, which can keep you full longer. But they have another benefit -- they're very sweet. This means berries can satisfy your sweet tooth for a fraction of the calories you would take in gobbling cookies or brownies. Blueberries stand out because they're easy to find and loaded with antioxidants.
Raw vegetables make an outstanding snack. They satisfy the desire to crunch, they're full of water to help you feel full, and they're low in calories. Half a cup of diced celery has just eight calories. Bonci suggests coating celery with a little peanut butter or dunking carrots in salsa. When you're in the mood for chips and dip, try replacing the chips with raw veggies.
Think of the typical toppings on your baked potato -- butter, sour cream, maybe cheese and bacon bits. If you substitute a sweet potato, you might not need any of that. Baked sweet potatoes are so full of flavor, they require very little embellishment. This can save you loads of calories. As a bonus, sweet potatoes are packed with potassium, beta carotene, vitamin C, and fiber.
Studies suggest eating protein in the morning will keep your hunger at bay longer than eating a bagel or other carbs. One egg has only 75 calories but packs 7 grams of high-quality protein, along with other vital nutrients. Bonci adds that your body will burn more calories digesting eggs than a carb-heavy breakfast. If you have high cholesterol, check with your doctor about how many eggs you can eat per week.
It sounds too good to be true -- one of your favorite beverages may actually help rev the metabolism and help you lose weight. Bonci says coffee does stimulate the metabolism -- a little. She cautions that the effect is small and is easily cancelled out by the extra calories in a mocha cappuccino.
Oatmeal has three things going for it: fiber-rich whole-grain oats, lots of water, and it's hot. Bonci says this is a very filling combination. Hot food takes longer to eat, and all that liquid and fiber will help you feel full longer. "Don't buy the one that's already sweetened," Bonci says. "You can choose how to flavor it." Stirring in cinnamon or nutmeg will give you a sweet taste with less sugar.
Whole-grain rye crackers, sometimes called crispbreads, offer a low-fat, fiber-packed alternative to traditional crackers. Research suggests people who replace refined grains with whole grains tend to have less belly fat. Whole grains also provide a richer assortment of plant nutrients. This doesn't just apply to crackers. You can get the same benefits by switching to whole-grain breads, cereals, and pastas.
A standout whole grain is bulgur wheat, the type found in tabouli. It's high in fiber and protein, but low in fat and calories. That helps you fill up with a minimum of calories. Bonci adds that the rich taste makes it satisfying. "It's flavorful, so you don't need to add a lot of oil," she says. To turn this dish into a meal, she suggests adding beans and stirring in extra tomato, cucumber, and parsley.
Soup -- we're talking broth-based, not creamy -- is a dieter's friend in several ways. It's full of water, which fills you up with the fewest possible calories. It's hot, which prevents you from guzzling it down too quickly. When eaten before a meal, soup can take up space that might have gone to higher calorie foods. You can also make a satisfying, low-calorie meal out of soup alone by adding chicken, fish, cut-up vegetables, or beans.
Another way to fill up before a meal is by eating salad. Lettuce has plenty of water content to take up space in the stomach. That leaves less room for fattier foods that might come later in the meal. Make your salad interesting by adding a variety of fruits and vegetables or grated cheese. But be careful about dressing, which can add a lot of calories. Bonci recommends using salsa, hummus, or black bean dip as dressing.
If you dress your salad with oil and vinegar, you may get another fat-fighting benefit. More research is needed, but some studies suggest vinegar may help the body break down fat. Whether or not this effect pans out, Bonci says vinegar is a good choice. It's full of flavor that can make salad more satisfying -- and it has no calories.
Nuts are an excellent way to curb hunger between meals. They're high in protein, fiber, and heart-healthy fats. Studies suggest nuts can promote weight loss and improve cholesterol levels when eaten in moderation. The key is to "be careful with quantity," Bonci tells WebMD. "Choose something in a shell, so you have to work harder and slow down."
Three cups of plain, air-popped popcorn may seem like a whole lot, but the calorie content is low. All that air adds volume without adding fat or sugar. "When people are looking to snack, they don't stop at 10 potato chips," Bonci says. They want to have their fill, and a big bowl of popcorn delivers. "It's visually satisfying, plus it takes time to eat."
Skim milk provides plenty of protein and calcium with none of the fat found in whole milk. And even though it's fat-free, skim milk can help you feel full. It takes longer to leave the stomach than drinks with less protein, Bonci says. There's also evidence that skim milk and other nonfat dairy foods may promote weight loss, particularly around the mid-section. More research is needed to confirm this effect.
As we've seen, protein can keep you full longer and burn more calories during digestion. But you want to choose your protein carefully. Dark meat tends to be high in fat, which could cancel out some of the benefits. Skinless chicken breast is a great choice. And some cuts of beef can make the grade. Flank steak, eye of round, and top sirloin are extra-lean with less than 4 grams of saturated fat per serving. Just stick with a 3- to 4-ounce portion.
One of the best sources of protein is fish. Studies show it's more satisfying than chicken or beef, probably because of the type of protein it contains. Most fish is low in fat, and the exceptions usually have a healthy form of fat -- omega-3 fatty acids. Omega-3's, which are found in salmon, herring, and other fatty fish, appear to help protect against heart disease and other chronic conditions.
Beans deliver a nutritional triple punch, Bonci says. They're a vegetable, a protein, and a great source of fiber. This means they'll help you stay full for the price of very few calories. They're also easy to prepare when the munchies strike. Open a can of garbanzo beans and toss them into soup or salad or mash them up to use as a dip. One cup packs 12 grams of fiber, just 4 grams of fat, and 15 grams of protein.
