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.


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.
Hello, hydration. Watermelon, which gets its pretty color from the antioxidant lycopene, is a juicy, delicious way to make sure you’re staying hydrated—a key factor in weight loss for various reasons. When you’re drinking enough water, all your systems (including your metabolism) are better able to work at their maximum capacity, Shawn Talbott, Ph.D., a nutritional biochemist, told SELF in a previous article. Plus, proper hydration prevents you from confusing thirst for hunger, which can lead you to overeat throughout the day. And don’t buy into the hype about watermelon being a calorie bomb—1 cup only contains 46 calories.
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.
Yes, peanut butter is high in calories, but if you stick the real stuff—a tasty combo of peanuts and maybe a touch of salt—the legumes can earn a place as one of the best foods for weight loss. In addition to providing you with belly-slimming monounsaturated fats, tummy-filling fiber, and metabolism-boosting protein, peanuts also contain genistein, a compound that helps turn down the genes for obesity and reduces your body’s ability to store fat.
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.

Fears of high cholesterol were frequently voiced up until the mid-1990s. However, more recent research has shown that the distinction between high- and low-density lipoprotein ('good' and 'bad' cholesterol, respectively) must be addressed when speaking of the potential ill effects of cholesterol. Different types of dietary fat have different effects on blood levels of cholesterol. For example, polyunsaturated fats tend to decrease both types of cholesterol; monounsaturated fats tend to lower LDL and raise HDL; saturated fats tend to either raise HDL, or raise both HDL and LDL;[42][43] and trans fat tend to raise LDL and lower HDL.

These foods—notably vegetables, fruits, legumes, and whole grains—should supply about 20 to 35 grams of dietary fiber a day, depending on your calorie needs. (Aim for 14 grams of fiber for every 1,000 calories, as advised by the  Dietary Guidelines for Americans.) Fiber slows the absorption of carbohydrates, so they have less effect on insulin and blood sugar, and it provides other health benefits. Try to fill three-quarters of your plate with produce, legumes, and whole grains—leaving only one-quarter for meat, poultry, or other protein sources.


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!

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.

You could complicate things if you wanted to, but why bother when the simple way tastes so great? Not counting salt, pepper, and oil, this recipe contains just six ingredients—and tastes like a million bucks. That’s because the lightly seasoned chicken releases all its chicken-y goodness into the skillet, where onions, garlic, kale, and chickpeas lap it up so that none of the rich poultry flavor goes to waste. If you can, purchase air-chilled and/or organic chicken thighs. Since chicken is the star here, you want the best you can find.
Try a lower-calorie version. Use lower-calorie ingredients or prepare food differently. For example, if your macaroni and cheese recipe uses whole milk, butter, and full-fat cheese, try remaking it with non-fat milk, less butter, light cream cheese, fresh spinach and tomatoes. Just remember to not increase your portion size. For more ideas on how to cut back on calories, see Eat More Weigh Less.

Carbs are not the nutritional Voldemort. Actually, certain healthy carbs can help you lose weight—and air-popped popcorn is one of them. “Portion-wise, it has a lower calorie per unit volume than many other snacks,” Lauren Harris-Pincus, M.S., R.D.N., and owner of Nutrition Starring You, told SELF in a previous article. You get more bang for your caloric buck, and since popcorn is made up of complex carbs, it’ll digest more slowly, keeping you fuller longer.
Challenge yourself to come up with two or three dinners that can be put together without going to the store—utilizing things in your pantry, freezer, and spice rack. A delicious dinner of whole grain pasta with a quick tomato sauce or a quick and easy black bean quesadilla on a whole wheat flour tortilla (among endless other recipes) could act as your go-to meal when you are just too busy to shop or cook.

Vending machines in particular have come under fire as being avenues of entry into schools for junk food promoters. However, there is little in the way of regulation and it is difficult for most people to properly analyze the real merits of a company referring to itself as "healthy." Recently, the Committee of Advertising Practice in the United Kingdom launched a proposal to limit media advertising for food and soft drink products high in fat, salt or sugar.[46] The British Heart Foundation released its own government-funded advertisements, labeled "Food4Thought", which were targeted at children and adults to discourage unhealthy habits of consuming junk food.[47]

The American Heart Association, World Cancer Research Fund, and American Institute for Cancer Research recommend a diet that consists mostly of unprocessed plant foods, with emphasis a wide range of whole grains, legumes, and non-starchy vegetables and fruits. This healthy diet is full of a wide range of various non-starchy vegetables and fruits, that provide different colors including red, green, yellow, white, purple, and orange. They note that tomato cooked with oil, allium vegetables like garlic, and cruciferous vegetables like cauliflower, provide some protection against cancer. This healthy diet is low in energy density, which may protect against weight gain and associated diseases. Finally, limiting consumption of sugary drinks, limiting energy rich foods, including “fast foods” and red meat, and avoiding processed meats improves health and longevity. Overall, researchers and medical policy conclude that this healthy diet can reduce the risk of chronic disease and cancer.[11][12]
You’ll want to add a pop of blue to your meals with this berry delicious fruit. “Research has linked eating a diet rich in fruits and non-starchy vegetables with weight loss, but I really like blueberries because they're packed with antioxidants and are available all year round in the frozen aisle,” says Rizzo. Add to yogurt, oatmeal, and salads, or use for sweetness in smoothies, sauces, and dressings.
Dietary cholesterol is only found in animal products such as meat, eggs, and dairy. The effect of dietary cholesterol on blood cholesterol levels is controversial. Some studies have found a link between cholesterol consumption and serum cholesterol levels.[44] Other studies have not found a link between eating cholesterol and blood levels of cholesterol.[45]
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.
