Even if you fill up on produce, lean proteins, and whole grains, according to British Journal of Nutrition findings, when you think about the quality of your diet, you’re likely forgetting about all the unhealthy food that also finds its way to your mouth. People tend to exaggerate the good foods they eat and underestimate the bad stuff, says study author, Kentaro Murakami, PhD of Japan’s University of Shiga Prefecture. While it’s not necessarily intentional, it’s likely one of the reasons why it’s so hard for people to lose weight. For example, you might grab a handful of candy at a co-worker’s desk or a sample at the mall and then forget about it altogether. Our advice: To get a more accurate overview of your diet, keep a detailed food journal on your phone—yes, that means you should include that food court sample, too. Whether you snap photos or keep a written log is totally up to you—both tactics will work. The more food records dieters kept over the course of 30 months, the more weight they lost, a study in the American Journal of Preventive Medicine found.
Not only does zinc help protect you from the sun, but the element has also been shown to impact weight loss. 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.
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.
Alcohol isn’t exactly a weight loss ally, but using it to flavor meat when you cook it could help you drop a few pounds and stay healthy. According to a study in the Journal of Agricultural and Food Chemistry , if you marinate meat with beer for four hours, you can lower the harmful chemicals it produces when exposed to high heat by up to 68 percent.
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.
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.
Kamut, also known as Khorasan wheat, is an ancient grain native to the Middle East that packs in heart-healthy omega-3 fatty acids and protein while remaining low in calories. In fact, a half-cup serving of the stuff has 30 percent more protein than regular wheat and only 140 calories. A study published in the European Journal of Clinical Nutrition found that noshing on Kamut reduces cholesterol, blood sugar, and cytokines (which cause inflammation throughout the body).
The best diet for losing weight is Weight Watchers, according to the experts who rated the diets below for U.S. News. Volumetrics came in second, and the Flexitarian Diet, Jenny Craig and the vegan diet were third on this overall weight loss ranking list, which takes into account short-term and long-term weight loss scores. Some other diets performed as well or better in our rankings for enabling fast weight loss, but long-term weight loss is more important for your health.
Fill at least half of your lunch and dinner plate with vegetables. Vegetables are nutrient-dense, high in satiating fiber, and low in calories, making them ideal weight loss tools, says registered dietitian Danielle Omar. “By eating the veggie half of your plate before anything else, you will take the edge off your hunger, eat less overall calories, and still feel full and satisfied. Keep eating this way and the pounds will painlessly melt away.”
If you have a big celebration or date coming up, you might think it makes sense to “save” your calories for when it’s time to let loose, but this technique is rarely effective and could actually be hindering your ability to lose weight. “Although this makes sense in theory—consuming fewer calories total per day—it rarely works out as cleanly as we like,” Lisa Hayim spelled out for us in The 30 Worst Diet Mistakes You’re Making. “By the time you get to the date, and have a drink or two, the feelings of extreme hunger rush in, and you’re grabbing for whatever you can get your hands on, which is usually foods high in calories and fat. You’re so hungry, you may even end up consuming more than a day’s worth of calories in one sitting! Plus, with alcohol in your system, your body is less able to efficiently metabolize the calories,” explains Hayim. “Instead, consume normal meals throughout the day, arrive at your date cool, calm, and collected, and enjoy your cocktail and eat responsibly.”
Hold on right there if you thought fats were bad. Because no, they are not. Not all. Fats, just like the other nutrients, are essential to keep the body functioning at the optimum level. They keep your skin and hair healthy, and also help absorb vitamins A, D, E, and K (also called the fat-soluble vitamins) (19). The trick lies in differentiating the good fats from the bad. Sources of good fats include foods rich in omega-3 fatty acids, avocados, and walnuts (20). These are beneficial in many ways, some of which include keeping the heart healthy, preventing arthritis, dementia, and depression. Most important, good fats have also been found to contribute to healthy weight loss (21).
“They may be small, but these sweet-tasting fruits contain a hefty amount of actinidin, a natural enzyme unique to kiwifruit that aids in digestion by breaking down protein in the body. Kiwifruit also contains prebiotic fiber, which primes the gut for healthy digestion,” Scritchfield says. “Research indicates that a daily serving of green kiwifruit helps increase bowel movements. So, cut in half, scoop with a spoon, and pop into your mouth like nature’s Tums (SunGold kiwis, with a yellow flesh and tropical taste, offer three times the vitamin C of oranges and as much potassium as a medium banana).”

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.
