A study in the journal Metabolism found that eating half a grapefruit before meals may help reduce visceral fat and lower cholesterol levels. Participants in the 6-week study who ate a Rio Red grapefruit fifteen minutes before each meal saw their waists shrink by up to an inch, and LDL levels drop by 18 points. Though researchers don’t exactly know what makes grapefruit so good at burning fat, they attribute the effects to a combination of phytochemicals and vitamin C found in the tart treat.
We’ve said it before and we’ll say it again: fat is your friend! To be more specific, healthy fats will be your weight loss friends. Consider adding extra virgin olive oil to your diet and you might see the scale start to tip in your favor. One Journal of Women’s Health study discovered that an EVOO-enriched diet helped participants lose more weight than those on a low-fat diet. Like peanuts and avocados, extra virgin olive oil’s belly-blasting abilities are thought to be a result of the monounsaturated fats it contains.
According to a study published in Bioscience, Biotechnology, & Biochemistry , consuming apple cider vinegar each day can lead to weight loss, reduced belly fat, waist circumference, and lower blood triglycerides. More specifically, the study of obese Japanese participants found that those who consumed just one tablespoon of ACV over a three-month period lost 2.6 pounds, and those who consumed 2 tablespoons lost 3.7 pounds in the same time frame. Go ahead and toss a tablespoon or two of this calorie, fat, and sugar-free stuff in your next salad dressing, sauce, or smoothie.
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.
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.

A squeeze of lemon adds instant freshness to everything from drinks to salads to fish without additional calories, making it an ideal way to flavor food if you're watching your weight. Plus, the pectin fiber in lemons can help fill you up and fight off hunger cravings. And while it hasn't been scientifically proven, some experts believe that the citrus fruit can aid in weight loss, as well.
Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
