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.
It’s a dietary miracle: A fat that makes you skinny. Dietary supplementation of coconut oil actually reduced abdominal obesity in a study published in the journal Lipids. Of the participants, half were given two tablespoons of coconut oil daily and the other half were given soybean oil, and although both groups experienced overall weight loss, only the coconut oil group saw smaller waistlines. And other researchers have also pointed to the waist-whittling effects of the tropical oil. In a separate study of 30 men, those who ate 2 tablespoons of coconut oil a day shrank their waists by an average of 1.1 inches in one month.

And eating just 1.5 ounces of almonds daily led to a reduction in belly and leg fat, a 2015 study published in the Journal of the American Heart Association showed. For added effect, eat almonds before working out: The amino acid L-arginine can help you burn more fat while building muscle.
Surprised? Although olive oil contains fat, it actually contains a type of healthy fat that has been found to decrease levels of fat-storing inflammation. According to a review published in the International Journal of Molecular Sciences, a polyphenol only found in unrefined extra virgin olive oil—oleocanthal—reduces inflammation in a similar way that ibuprofen does: it prevents the production of two pro-inflammatory enzymes, COX-1 and COX-2.
This classic lunchbox sandwich condiment is teeming with flat-belly nutrients such as cholesterol-lowering monounsaturated fats and is a great source of plant-based protein.
