You may also know this root veggie as a sunchoke since they're the roots of a type of sunflower. According to a Canadian study, subjects whose diets were supplemented with a type of gut-healthy insoluble fiber called oligofructose not only lost weight but reported less hunger than those who received a placebo. Researchers discovered that the subjects who consumed the prebiotic fiber had higher levels of ghrelin—the hunger-suppressing hormone—and lower levels of blood sugar. And you guessed it: Jerusalem artichokes are one of the best sources of the fiber.
The phrase "slow carb" is anything but sluggish when it comes to blasting fat. Slow carbs are digested slowly, which keeps you feeling fuller and energized longer—and sweet potatoes are one of them. Among the magic ingredients here are carotenoids, antioxidants which stabilize blood-sugar levels and lower insulin resistance, which helps your body efficiently convert calories to energy rather than stored as fat. And their high vitamin profile (including A, C, and B6) give you more energy to burn at the gym.
This brilliantly orange root is a powerful fat fighter. According to a 2009 study by the USDA, mice whose diets were supplemented with turmeric experienced reduced weight gain and body fat levels even when their food intake was not changed. Experts believe the power of this spice comes from the active ingredient curcumin: Studies, including one published in the journal Journal of Traditional and Complementary Medicine, have found that curcumin is one of the most effective anti-inflammatory options out there. Because it's more difficult for your body to lose weight when you're fighting off inflammation, adding anti-inflammatory turmeric will help you achieve your weight loss goals.

After your diet, and once you cycle off of your fat burner, it's important to bump your calories back up to or above what is known as "maintenance," where your calories and calorie burn are roughly equal. One popular way to do this is what is known as a "reverse diet," where you gradually and systematically raise calories. Registered dietician Katie Coles explains how in her article "The Ultimate Guide to Reverse Dieting."
I'm not telling you that it's easy, but it really is pretty simple. In an age where people don't even have to go outside to grill a steak, it's tempting to spend a few dollars on a quick fix. Human anatomy hasn't changed much throughout history, however. If you adopt your grandparents' work ethic and apply it to your every day life, you will achieve your greatest results.
Research suggests these magical pulses are one of the closest things we have to a fat-burning pill. For starters, beans are a great source of resistant starch, a type of slow-digesting, insoluble fiber that feeds the healthy bacteria in your gut, triggering the production of the chemical butyrate, which encourages the body to burn fat as fuel and reduces fat-causing inflammation. They're also one of the top sources of soluble fiber. A recent study by Wake Forest Baptist Medical Center researchers found that for every additional 10 grams of soluble fiber eaten per day, a study subject's belly fat was reduced by 3.7 percent over five years. Black beans? One cup boasts an impressive 4.8 grams of soluble fiber.
This Asian veggie dish is made by fermenting a blend of cabbage, radishes, and scallions with a seasoned paste of red pepper, salted shrimp, or kelp (koji) powder. Fermented foods are great for healing your gut thanks to the high levels of probiotics, but the unique strains found in kimchi may also help you stay slim: Researchers at Kyung Hee University in Korea induced obesity in lab rats by feeding them a high-fat diet. The group that got a Lactobacillus brevis supplement— the culture strain found in kimchi—was able to suppress the diet-induced increase in weight gain by 28 percent! If kimchi isn't your thing, also consider adding one of these probiotic foods for a healthier gut to your diet.
