This easy a.m. ritual works on two levels. First, a recent study found that exposure to sunlight in between the hours of 8 am and noon reduced your risk of weight gain regardless of activity level, caloric intake, or age. Researchers speculate that the morning light synchronizes your metabolism and undercuts your fat genes. And burning calories before you eat means you’re exercising in a fasted state—the energy you burn comes right from your fat stores, instead of the food you ate. But what really stunned Martha was the improvement in her heart health. Before starting Zero Belly Diet, Martha’s heart rate would typically soar to 112 beats per minute (bpm) within moments of starting her exercise bike workout. “After the first week and a half I could not raise my heart rate over 96 bpm with the same workout. It was great to see change in the mirror, and even better to know good things were happening that I couldn’t even see.”
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.
The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.
Doing crunches until the cows come home? Stop it! When you're down to your final inches of belly fat, the dreaded crunch won't be the exercise that finally reveals your six-pack. "You can't spot reduce," Jill says. Instead, she suggests doing functional exercises that use the muscles in your core—abdominals, back, pelvic, obliques—as well as other body parts. "These exercises use more muscles, so there is a higher rate of calorie burn while you are doing them," she says. Planks are her favorite functional exercise—they activate not just your core muscles but also your arm, leg, and butt muscles.
A University of Michigan study found that lab rats who nommed on a diet enriched with powdered blueberries had less abdominal fat after 90 days than rats who ate a standard diet. The researchers suspected that blueberries are so good at targeting belly fat because of their high levels of phytochemicals, a naturally occurring antioxidant. FYI, blueberries are also an excellent source of fibre.
