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.
Carbs are not the enemy. Not whole-grain carbs, that is. People who ate three or more daily servings of whole grains (such as oats) had 10 percent less belly fat than people who ate the same amount of calories from processed white carbs (bread, rice, pasta), according to a Tufts University study. It’s theorized that this is due to whole grains’ high fiber and slow-burn properties, which keep you satiated longer.
Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time without exercise. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a cherry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.
