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.
When it comes to condiments, mustard is about as healthy and low cal as it gets, and the pungent yellow stuff that contains about 5 calories per teaspoon has also been found to stimulate weight loss. Scientists at England’s Oxford Polytechnic Institute found that eating just one teaspoon of mustard can boost the metabolism by up to 25 percent for several hours after it’s been consumed. Researchers attribute this to capsaicin and allyl isothiocyanates, phytochemicals that give the mustard its characteristic flavor. So instead of reaching for the sickeningly sweet ketchup, make sure you have mustard on hand at your next BBQ.
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.
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.
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. 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.
There's a reason (well actually, many reasons) why lentils are considered one of the world's healthiest foods. With 13 grams of protein and 11 grams of fiber per serving, this legume—another member of the pulse family—will keep you feeling full for hours in between meals. They're a great source of fat-burning resistant starch, too, with 3.4 grams in a half-cup serving.
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.
Blueberries are lousy with antioxidants, satiating fiber, potassium, and more, and according to researchers at the University of Michigan, the colorful fruits may also encourage weight loss. In a study of laboratory rats, scientists found that after 90 days the rats who consumed blueberry-enriched powder as 2 percent of their diet had less abdominal fat, lower triglycerides, lower cholesterol, and improved fasting glucose and insulin sensitivity, than the rats who didn’t consume any blueberry-enriched powder.
A 2016 study found that garlic powder reduces body weight and fat mass among people with non-alcoholic fatty liver disease (NAFLD). Recent studies have also shown that garlic supports blood-sugar metabolism, and helps control lipid levels in the blood. What’s more? Eating garlic can help boost your immune system, help ward off heart disease, fight inflammation, increase memory retention, and lower blood pressure, so consider adding some to your next meal. At the very least, it is preferable over salt, which can lead to water weight gain and bloating.
Is there anything avocados can't do? This creamy superfood (loaded with monounsaturated fats, potassium, magnesium, folate, and vitamins C and E) has been linked to improved vision, good heart health, and a reduced risk of certain cancers. And avocados can also help whittle your middle: according to one study, people who regularly consume them weigh less and have smaller waists than those who do not. Another study found that women who eat half an avocado at lunchtime might experience reduced food cravings later in the day.
