Yes, you can eat dark chocolate to lose weight. A study among women with normal weight obesity (or “skinny fat syndrome”) who ate a Mediterranean diet that included two servings of dark chocolate per day showed a substantial reduction in waist size than when on a cocoa-free meal plan. Researchers attribute dark chocolate’s weight loss abilities to flavonoids, heart-healthy compounds in the sweet treat that the scientists at Harvard say can reduce the risk of diabetes, heart disease, and mortality. Like nuts, dark chocolate has also been found to induce satiety. When reaching for chocolate, just make sure you choose a bar with at least 70 percent cacao. Anything less contains more belly-bloating sugar and a significantly reduced flavonoid content.
Although they're best known for containing potassium, bananas are also a great source of resistant starch, a type of starch that's important for weight loss. Your body digests resistant starch slowly—helping you feel full for longer—while simultaneously encouraging your liver to switch to fat-burning mode. And no need to wait for them to become completely ripe; bananas actually contain more of this calorie-torching ingredient when they're still a little green.
Sure, nuts aren’t known for being low in calories, but they have an array of other properties—namely a high protein and fiber content—that makes them ideal for weight loss. A study published in the Journal of the American Heart Association, Circulation, found that consuming 1.5 ounces of almonds daily (as opposed to a carb-dense muffin) along with a heart-healthy diet, helped to improve cholesterol and lipid profiles among the research participants. The study also found that eating almonds reduces belly fat, too.
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.
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.
“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.
If you want to sip your way to a faster metabolism, pour yourself a cup of green tea. The beverage is filled with powerful antioxidants that can help fight inflammation, burn fat, and increase energy. According to one study, drinking five cups a day could help you lose twice as much weight, mainly in your midsection. And drinking green tea could also reduce risk of Parkinson's disease, as well as ovarian, colorectal, skin, and prostate cancers.
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.
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.
Eggs are rich in high-quality protein, fats and essential nutrients, like vitamin D and choline. It's the protein, and the time of day we tend to eat them, that especially makes them a powerhouse for weight loss. Eating a high-protein breakfast promotes weight loss, because protein increases satiety while regulating hunger and appetite hormones, helping fend off your hunger until lunchtime. One study found that eating eggs for breakfast left people feeling more satisfied than those who had bagels—which helped them eat less throughout the day.
