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. According to a recent study presented at the annual Society for Endocrinology conference, researchers found that when protein is digested and broken down into amino acids in your body, one of those amino acids—phenylalanine—triggers hormones that help reduce appetite and ultimately leads to fat burn and weight loss. Go for brands that have an ingredient list of just two items: nuts and a little salt, or look to our guide: Best and Worst Peanut Butters.
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.
Keeping a toothbrush handy can do more than polish up that smile (and counter the effects of all that belly-slimming garlic); brushing your teeth throughout the day can also help you ditch that belly fat fast. A study conducted a sample of over 14,000 participants found that brushing after every meal was linked to lower weight. That minty toothpaste flavor not only clashes with virtually every food, brushing may also trigger a Pavlovian response that tells your brain the kitchen’s closed.
Foods rich in the amino acid leucine can help build the lean muscle mass that’s needed to trim excess fat from your frame, according to Jennifer McDaniel, MS, RDN, CSSD, LD. It literally jumpstarts the process of developing muscle mass—and red meats are one of the best sources around. Go grass-fed to get the added benefits of omega-3s and conjugated linoleic acids—these two fatty acids help to decrease the inflammation in your body that causes fat storage.
To start off, aim to do ab work 3 or 4 times a week on non-consecutive days with at least 24 hours of rest in between sessions, says Gagliardi. During those sessions, you can start with simpler moves like crunches, bicycle crunches, and planks. Even though you may only be directly targeting your abs 3 or 4 times a week, you should still be activating your core (aka, tightening your ab muscles) in every workout you do, says Gagliardi.
