Like peanuts, avocados contain metabolism-enhancing monounsaturated fats that have been shown to reduce hunger. In fact, a study in Nutrition Journal found that participants who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterwards. What’s more? The trendy toast topping is also loaded with unsaturated fats, which seem to prevent the storage of belly fat, as well as satiating fiber and free-radical-killing antioxidants.
Drinking enough water can help you stay slim, too. Research from the American Chemical Society in Boston found that having two 8-ounce glasses of water before a meal while also reducing portion sizes could help you lose weight and keep it off. Not to mention, water fills you up, curbing your appetite: "In addition to slightly boosting your metabolism, drinking water before meals has been shown to help you eat less without trying," says Sass.
Kamut is an ancient grain native to the Middle East that is an excellent source of heart-healthy omega-3 fatty acids, protein, and fiber, while simultaneously being low in calories. In fact, a half-cup serving of the stuff has 30 percent more protein than regular wheat and just 140 calories. What’s more? A study published in the European Journal of Clinical Nutrition found that eating Kamut reduces cholesterol, blood sugar, and cytokines (which cause inflammation throughout the body). Kamut’s ability to stabilize blood sugar and reduce inflammation make it a great weight loss staple, especially if it is used in place of nutritionally lacking refined grains.
A big reason to incorporate more strawberries into your diet: not only do they taste delicious, but a study from Harvard Medical School found that an increased intake of flavonoid-rich fruits, like strawberries, could help prevent weight gain. Stock up on the seasonal fruit in summer, but don't shy away from grabbing the frozen variety once colder temps hit — fruit is frozen at its nutrient peak, so you'll still nab most of the same health benefits.
A complete plant protein boasting all nine essential amino acids, quinoa is a weight loss superfood win. One cup of cooked quinoa has about 220 calories, 5 grams of fiber, and 8 grams of protein. “Complex carbohydrates like those in quinoa can help with satiety when eaten with other healthy foods (like heart-healthy avocados for a healthy dose of fats) that inevitably will help with weight loss in the long run,” explains Elizabeth Ann Shaw, MS, RDN, CLT, CPT.
Since avocados are packed with nutrients and healthy fats that can stimulate weight loss, it’s no surprise that avocado oil acts in a similar fashion. When Penn State University researchers compared those who consumed monounsaturated-rich oils (like high-oleic canola oil or avocado oil) with those who consumed a flax-safflower oil blend, they found that those who used just three tablespoons of the monounsaturated-rich oil daily lost nearly two percent of their belly fat in just one month.
Let's be real: Some nights, you need to eat out or order in. Check online menus before going out to prevent impromptu (read: poor) choices. A California roll with brown rice has only 26g carbs—that's half the carbs and triple the fiber in a white rice tempura (battered = carbs) roll.

Speaking of things you find in the sea, oysters have also been shown to contribute to weight loss thanks to their impressive zinc content. One study found that obese people who consumed 30 milligrams of zinc per day—the equivalent of just six raw oysters—had lower BMIs, weighed less, and showed improvements in blood cholesterol levels. If oysters aren’t your thing, spinach, pumpkin seeds, and mushrooms are also excellent sources of zinc.

Want to lose weight? Grab a bottle of V8! According to a study published in Nutrition Journal, tomato juice consumption can aid weight loss because it increases resting energy expenditure (REE)—the amount of energy expended by a person at rest. After eight weeks of drinking unsalted tomato juice twice daily, the 95 women in the study (who were each exhibiting some menopausal symptoms) increased their REE by an average of over 100 calories per day.
Good news, wine drinkers. Thanks to resveratrol, an antioxidant found in grape skin, drinking red wine in moderation can be part of a healthy diet. Some studies suggest that people who drink wine have smaller waists and less abdominal fat than those who drink mainly liquor. And having one glass of red wine can increase your body's calorie burn for up to 90 minutes afterwards. The antioxidants in wine might even help your body prevent cancer and improve heart health. Just be sure to stick to no more than a glass a day—the calories can add up fast.
If you want to sip your way to a faster metabolism, pour yourself a cup of green tea. The beverage is filled with powerful antioxidants that can help fight inflammation, burn fat, and increase energy. According to one study, drinking five cups a day could help you lose twice as much weight, mainly in your midsection. And drinking green tea could also reduce risk of Parkinson's disease, as well as ovarian, colorectal, skin, and prostate cancers.
With its trifecta of carbs, protein, and fat, Greek yogurt can keep you full and ward off hunger by keeping blood sugar levels steady. Instead of choosing the non-fat kind, go for 2 percent or one with whole milk—selecting non-fat is a surefire way to wind up hungry soon after downing your meal. A single cup of Fage Total 2 Percent has 170 calories, 4.5 grams of fat, and a whopping 23 grams of protein.
Spirulina is a powdered, high-protein seaweed supplement. The dried stuff is about 60 percent protein, and, like quinoa, it’s a complete protein, meaning it can be converted directly into muscle in the body and is thus a great weight loss tool. A tablespoon of the blue-green algae delivers 8 grams of metabolism-boosting protein for just 43 calories, plus half a day’s allotment of vitamin B12, which in and of itself can give you more energy and boost your metabolism. Try tossing some spirulina into a smoothie and watching the pounds melt off. For more skinny smoothie ideas, check out this list of smoothie recipes for weight loss!
Cabbage is rich in antioxidants and vitamin C but extremely low in calories (just 22 per cup), so you can fill your plate with the leafy green guilt-free. And while you're probably familiar with the infamous Cabbage Soup Diet, there are plenty of alternate ways to eat this veggie that won't leave you feeling hungry. It's delicious in a variety of slaws or salads, and makes a crunchy garnish atop tacos or burgers.
These support bone health and have other possible benefits. Dairy products are the best sources of calcium, but you can also get it from fortified foods as well as canned salmon, sardines, dark leafy greens, and most tofu. If you can’t get the recommended 1,000 to 1,200 milligrams a day from food, take a calcium supplement. It’s hard to consume enough vitamin D from foods (the RDA is 600 to 800 IU a day, though other experts advise more). Thus, many people—especially those who are over 60, live at northern latitudes, or have darker skin—should consider taking a supplement.
