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.
Whether you're headed to the beach, prepping for a special occasion or just want to jump-start a healthier lifestyle, you can set the foundation for belly fat loss in a week. And while you likely won't reach your final weight loss goals in a week -- unless you're only looking to lose a pound or two -- you might be able to see minor differences and burn some initial belly fat. However, the results from diet and exercise modifications can keep you motivated to stick to longer term goals, and they'll set you on a road to success -- without the high risk of weight regain associated with fad crash diets.
If you’re only getting a minimal amount of sleep each night, that leaves more time for you to snack and make otherwise unhealthy decisions that could affect your weight loss. Although it will vary from person to person on how much sleep you actually need to be most effective (and therefore make progress toward your weight loss goals), the ideal number is typically 7 or 8 hours, says Dr. Cheskin.

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.
Kickstart your morning—and your metabolism—with this warming spice. Cinnamon contains powerful antioxidants called polyphenols that are proven to alter body composition and improve insulin sensitivity (which means it keeps blood sugar stable, preventing hunger-inducing spikes and crashes). Japanese researchers found that mice who ate a daily helping of cinnamaldehyde (the ingredient that gives cinnamon its flavor) lost belly fat, while those who skipped the spice did not. Add it to your overnight oats or sprinkle some in your coffee to reap the benefits.
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it’s that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, a study published in Diabetes Care revealed that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.

You say tomato, I say 9-oxo-ODA. That’s the name of a compound found in the brilliant red fruits that Japanese researchers recently discovered can effectively activate your DNA to burn more fat. Tomatoes are also brimming in beta-carotene and lycopene, two potent antioxidants that mop up harmful compounds that promote fat storage. One Journal of Nutrition study found people whose diets contained the most beta-carotene and lycopene had the smallest waists and the least belly fat. And at only 5 calories apiece, grab a few sun-dried tomatoes! Cooked tomatoes contain more bioavailable lycopene than raw tomatoes, according to Cornell University researchers.
Greens such as collards and kale are making a difference to fat burn. Kale which is filled with vitamin K, Omega 3 essential fatty acids fiber and a rich calcium source. Lutein helps to ensure health of the eyes. Vitamin C and beta carotene can help in healthy bowel movements and enhance satiety, promoting general good health apart from low body fat.

There are plenty of fun ways to get moving and exercise. The key is figuring out what you find fun and then going and doing it. Many find classes like cycling, Zumba, hip hop, step, boot camp to be great fun, while others find their fun hitting the trails, playing tennis, biking, swimming, or even just walking with their dog. Sometimes a personal trainer, a friend, or even an online program can make any format of fitness fun as well. Be open minded and try everything you can. You won't be disappointed.
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.
This creates satisfaction and satiates the cravings for fast food, ensuring that you are full longer with fiber and high protein. It improves the metabolism to burn more calories across the day. Buy peanut butter from peanuts alone. Look for unprocessed freshly ground butter loaded with niacin that keeps the digestive system at optimal levels and prevents belly fat.

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.
