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.
Diets to promote weight loss are divided into four categories: low-fat, low-carbohydrate, low-calorie, and very low calorie. A meta-analysis of six randomized controlled trials found no difference between the main diet types (low calorie, low carbohydrate, and low fat), with a 2–4 kilogram weight loss in all studies. At two years, all of the diets in the studies that reduced calories caused equal weight loss regardless of whether changes in fat or carbohydrate consumption were emphasized.
No way could we have a “best foods for weight loss” list without this slice of heaven. Dark chocolate contains antioxidants known as flavonoids, which promote good heart health. As a bonus, an ounce of 70-85 percent cacao dark chocolate has 3 grams of fiber and 64 grams of magnesium, which supports nerve and muscle function, immune health, and bone strength. For maximum benefits, reach for a bar with at least 70 percent cacao. “The higher the percentage, the more antioxidant content,” according to Cleveland Clinic Wellness.
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.
Carbohydrates are one of your body’s main sources of energy. But most should come from complex, unrefined carbs (vegetables, whole grains, fruit) rather than sugars and refined carbs. Cutting back on white bread, pastries, starches, and sugar can prevent rapid spikes in blood sugar, fluctuations in mood and energy, and a build-up of fat, especially around your waistline.

“This warming—or cooling—beverage serves a dual purpose. Not only is it full of antioxidants and other healthy phytochemicals, but it has the benefit of slightly increasing your metabolism,” says Harris-Pincus. Sipping tea in the evening instead of snacking, or trading in your PSL for a cup of green tea will lower your calorie intake and help you burn a few extra calories. Just be sure to keep it unsweetened.
Make the right changes. When cutting back on unhealthy foods in your diet, it’s important to replace them with healthy alternatives. Replacing dangerous trans fats with healthy fats (such as switching fried chicken for grilled salmon) will make a positive difference to your health. Switching animal fats for refined carbohydrates, though (such as switching your breakfast bacon for a donut), won’t lower your risk for heart disease or improve your mood.
“Fish is a great source of satiating protein and is typically lower in calories than other animal proteins,” says Maggie Moon, MS, RD, author of The MIND Diet. “Sardines are a sustainable seafood choice, which are packed with heart-healthy and brain-healthy omega-3 fats,” she says. These healthy fats can help decrease inflammation and improve your mood while dieting.
A fat-burning superfood, grapefruit contains a compound that can lower the fat-storage hormone insulin, which in turn can lead to weight loss. In fact, eating half a grapefruit before each meal could help you lose up to a pound a week—even if you don't change anything else about your diet. Because grapefruits are 90% water, which fills you up, they also act as a natural appetite suppressant.
Another condiment worth utilizing in place of sugary dressings and marinades is apple cider vinegar. According to a study published in Bioscience, Biotechnology, & Biochemistry, consuming apple cider vinegar each day can lead to weight loss, reduced belly fat, waist circumference, and lower blood triglycerides. More specifically, the study of obese Japanese participants found that those who consumed 1 tablespoon of ACV over a three month period lost 2.6 pounds, and those who consumed 2 tablespoons lost 3.7 pounds in the same time frame. Go ahead and toss a tablespoon or two of this calorie, fat, and sugar-free stuff in your next salad dressing, sauce, or smoothie.
Think of each almond as a natural weight-loss pill. A study of overweight and obese adults found that, combined with a calorie-restricted diet, consuming a little more than a quarter cup of the nuts can decrease weight more effectively than a snack comprised of complex carbohydrates and safflower oil—after just two weeks! (And after 24 weeks, those who ate the nuts experienced a 62% greater reduction in weight and BMI!) For optimal results, eat your daily serving before you hit the gym. A study printed in The Journal of the International Society of Sports Nutrition found that almonds, rich in the amino acid L-arginine, can actually help you burn more fat and carbs during workouts.

Calcium and vitamin C team up well to boost metabolism, and broccoli is just one of several healthy foods that contain both nutrients. What sets broccoli apart from the others, however, is that the green veggie also contains kind of fiber that’s been shown to increase the digestion, absorption and storage of food, also known as the thermic effect of food or TEF. Combine a revved up metabolism with an increased TEF and you get a match made in weight loss heaven!
Going gluten-free may be a popular trend, but unless you're actually gluten-intolerant or have celiac disease, plenty of reasons exist to continue eating whole grains. They're a tasty way to fill up on both soluble and insoluble fiber, which help you feel full for longer and keep bowel movements regular (oats, barley, and bulgur are especially high sources). Whole grains can also help prevent weight gain: in one study, women who ate whole grains like wheat germ and dark bread had a 49% lower risk of "major" weight gain over time.
In addition to dietary recommendations for the general population, there are many specific diets that have primarily been developed to promote better health in specific population groups, such as people with high blood pressure (as in low sodium diets or the more specific DASH diet), or people who are overweight or obese (in weight control diets). However, some of them may have more or less evidence for beneficial effects in normal people as well.
We’ve said it before and we’ll say it again: fat is your friend! To be more specific, healthy fats will be your weight loss friends. Consider adding extra virgin olive oil to your diet and you might see the scale start to tip in your favor. One Journal of Women’s Health study discovered that an EVOO-enriched diet helped participants lose more weight than those on a low-fat diet. Like peanuts and avocados, extra virgin olive oil’s belly-blasting abilities are thought to be a result of the monounsaturated fats it contains.
Fruit and vegetables are low in calories and nutrient dense, which means they are packed with vitamins, minerals, antioxidants, and fiber. Focus on eating the recommended daily amount of at least five servings of fruit and vegetables and it will naturally fill you up and help you cut back on unhealthy foods. A serving is half a cup of raw fruit or veg or a small apple or banana, for example. Most of us need to double the amount we currently eat.
Think smaller portions. Serving sizes have ballooned recently. When dining out, choose a starter instead of an entree, split a dish with a friend, and don’t order supersized anything. At home, visual cues can help with portion sizes. Your serving of meat, fish, or chicken should be the size of a deck of cards and half a cup of mashed potato, rice, or pasta is about the size of a traditional light bulb. By serving your meals on smaller plates or in bowls, you can trick your brain into thinking it’s a larger portion. If you don’t feel satisfied at the end of a meal, add more leafy greens or round off the meal with fruit.
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.
