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.
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.
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.
As found in nuts, seeds, fish, avocados, and plant oils. You should consume these high-fat foods in place of other high-calorie foods; otherwise, you’ll be adding excess calories to your diet. For instance, substitute olive or canola oil for butter, and nuts for chips. Fatty fish may reduce the risk of heart disease and have other benefits, attributed at least in part to their omega-3 polyunsaturated fats.
Kefir is a yogurt-like substance, but it actually contains less sugar and more protein than conventional yogurt while remaining packed with gut-friendly probiotics that can help you lose weight by aiding digestion. In one study, kefir displayed weight loss properties similar to those of milk and other dairy-rich products. Other probiotic-rich foods include kombucha, bone broth, and fermented items such as sauerkraut and kimchi.
Kimchi is a spicy Korean condiment that's made with fermented cabbage and is a great source of vitamins A, B, and C. Because it's fermented (like sauerkraut), kimchi contains tons of those good probiotics that aid the body in digestion. A recent study in the Proceedings of the National Academy of Science found that maintaining healthy bacteria in your gut can improve gut lining, which in turn could help reduce fat mass and inflammation.
Popular diets, often referred to as fad diets, make promises of weight loss or other health advantages such as longer life without backing by solid science, and in many cases are characterized by highly restrictive or unusual food choices.:296 Celebrity endorsements (including celebrity doctors) are frequently associated with popular diets, and the individuals who develop and promote these programs often profit handsomely.:11–12
Try not to think of certain foods as “off-limits.” When you ban certain foods, it’s natural to want those foods more, and then feel like a failure if you give in to temptation. Start by reducing portion sizes of unhealthy foods and not eating them as often. As you reduce your intake of unhealthy foods, you may find yourself craving them less or thinking of them as only occasional indulgences.
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.
Food processing isn’t always a bad thing: Cooking and preparing raw ingredients at home is also processing them. But the word “processed” is almost always reserved for commercial foods, usually packaged. Highly processed foods are industrially formulated mixtures that are no longer recognizable as their original plant or animal sources—everything from hot dogs and margarine to ice cream, candy, and many packaged snack foods. Such foods, which supply more than half the daily calories in most U.S. households, lack key nutrients and fiber and are high in sugars and sodium.
Coconut oil is having a moment right now: it can be used as a butter or olive oil substitute in everything from baked goods to salad dressing, and can even be used as an alternative to milk in lattes (yes, really). Sass is a fan of the heart-healthy oil whipped into smoothies, and you can also use it to sauté veggies, sear fish, or as an olive oil replacement in soups and stews. (It's also a must-add to your beauty routine, and makes a wonderful natural moisturizer for skin and hair.)
Salmon is a rich source of high-quality protein and provides plenty of "good" fats: omega-3 fatty acids. A diet rich in omega-3 fatty acids helped people feel more satisfied when they were watching their calories, per a study in Appetite. Eating salmon can be a delicious and versatile way to get your recommended two weekly servings of heart-healthy fish.
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.
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.
Grapes were basically made to be snacked on, and always having some on hand could be great for your weight loss goals — a study published in PLOS Medicine found the sweet fruit can aid in shedding unwanted pounds. If you're trying to resist a calorie-heavy dessert, try tossing a bunch into the freezer so you can pop a few whenever you're craving something sweet.
“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.
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.
If you’re on a quest to jumpstart weight loss, why not kick your metabolism into overdrive by sneaking spicy foods into your diet. Capsaicin, the active ingredient in cayenne pepper that gives it its spiciness, revs up your metabolism in a way that’s conducive to weight loss. In fact, according to a study in the American Journal of Clinical Nutrition, those who supplemented their diet with capsaicin consumed 200 fewer calories during their next meal.
Wouldn’t it be great if life came with a magic remote control that made the bad parts speed up and the good parts slow down? You could hit FF at the beginning of every workday, and RWD at the end of awesome date. All the vacations, holidays and parties could move at the pace of a Kenny G song, and all the endless conference calls could spin by faster than Nicki Minaj’s hairstyles.
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.
