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.
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. (Struggling to get that shut-eye? This doctor-approved breathing exercise will help you fall asleep fast.)
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.
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.
Don’t pass up on this cheap trick. “One of the most under-appreciated magic fat-burning elixirs is water,” says Ajia Cherry, ACE, CHC, CPT, personal trainer and Founder at Functional Innovative Training. “The more water you drink, the fuller you will feel, the easier it is to cut back on unnecessary calories. That’s an essential element of weight and fat loss,” she explains. Water is necessary to keep your metabolism functioning optimally. For even more of a kick, add a lemon to your glass. D-limonene, an antioxidant in lemon peel, has been shown to have a therapeutic effect on metabolic disorders in mice with high-fat-diet-induced obesity.
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.
If you don’t have an established exercise routine, simply walking is the best first step toward weight loss. “Walking is a pretty good entry point for people,” says Gagliardi. This is particularly true if you have been out of the gym for a while and want to ease back into a workout routine. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50 to 70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group.
Exercise every day. A week is a short time, so commit to strenuous exercise to reach your goal. An hour of intense cardio will help you burn calories and sweat out some of your water. Just be sure to drink water to replace what comes out in the sweat or your body will be dehydrated. You'll also want to work on your ab muscles, which will help you stand taller and look slimmer. Do exercises that focus on each area of the abs -- upper, lower and obliques.
But you'll lose the most fat by doing HIIT, or high-intensity interval training. This training technique involves working at full throttle for short intervals -- typically 10 seconds to a minute -- then recovering at a slow pace or resting for a minute or two. It increases your metabolism after a workout, since your muscles need to work hard to get "back to normal." HIIT also burns more belly fat than traditional, steady-pace cardio, according to Penn State University.
