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.
You may not think of them as a weight-loss food, but eggs are packed with protein, which helps curb your appetite. One study found that overweight women who ate eggs for breakfast were able to lose twice as much weight as women who started their days with bagels. And egg whites in particular are a good source of branched-chain amino acids, which help keep your metabolism running smoothly.
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.
A 2012 CDC study found that the average adult consumes about 100 calories worth of alcohol daily, but favoring a glass of wine instead of beer or sugary cocktails can drastically reduce that figure and make your waistline slimmer. In addition to having fewer calories than most alcoholic beverages, red wine, in particular, is a good source of those waist-shrinking flavonoids that are also found in red fruits. Resveratrol, a particular flavonoid found in red wine, is believed to have heart health benefits because it helps prevent blood vessel damage and reduces your ‘bad cholesterol.’ Just remember to imbibe in moderation.
It’s time to focus on your lentil health. In one four-week Spanish study, researchers found that eating a calorie-restricted diet that includes four weekly servings of legumes aids weight loss more effectively than an equivalent diet that doesn’t include beans. Those who consumed the legume-rich diet also saw improvements in their “bad” LDL cholesterol levels and systolic blood-pressure. To reap the benefits at home, work lentils, chickpeas, peas and beans into your diet throughout the week.
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.
Greek yogurt is an extremely satiating breakfast or snack, thanks to its thick, creamy texture and a whopping 17 grams of protein (nearly three times more than is in an egg, in fact). A study from the journal Appetite found that people who ate a high-protein yogurt snack three hours after lunch felt fuller and ate dinner later than the other participants. And on top of that, other studies suggest that the acids produced during yogurt fermentation might help increase feelings of fullness.
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.
Potatoes often get a bad rap, but when it comes to weight loss they're hard-to-beat sources of scale-dropping fiber. According to the Cleveland Clinic, sweet potatoes will up the insoluble fiber in your diet, keep you full longer, and you can bake and eat one for just 114 calories. Just watch what you load it with — instead of cheese or sour cream, opt for good-for-you fillings like black beans, tomatoes, and bell peppers.
“Thirst and hunger cues feel similar, so it’s important to stay hydrated, especially if you’re trying to lose weight,” explains Moon. Yes, plain water is important, but 20 percent of our daily water intake comes from foods, she says. “Watermelon is 92 percent water, plus it is bursting with vitamins A and C and anti-inflammatory nutrients like lycopene,” she explains.
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.)
Riffing off the flavor of a Greek gyro, these turkey burgers cook up fast in a cast-iron skillet or grill pan. Lemony, olive-studded yogurt sauce adds more Middle Eastern–inspired flavor and is a tasty alternative to ketchup and mustard. Piled high with arugula, cucumber, and red onion, these are filling enough to be called dinner. Or, round out the meal with roasted potato fries. For the juiciest burgers, go for 93% lean ground turkey (a combination of white and dark meat).
The average American consumes approximately 15.5 pounds of pasta each year—and most of it is the refined white stuff. Unfortunately, this type of noodle is usually void of fiber and micronutrients. Spaghetti squash, on the other hand, boasts only about 40 calories per cup—more than 75 percent fewer calories than a cup of plain pasta—and is an excellent source of vitamin A and potassium. Make this simple swap to jumpstart your weight loss and you’ll be fitting into your skinny jeans in no time! For more swaps to save you calories, don’t miss these food swaps that cut calories.
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.
