Resolve to do more prying. Oysters are one of the best food sources of zinc, a mineral that works with the hormone leptin to regulate appetite. Research shows that overweight people tend to have higher levels of leptin and lower levels of zinc than slimmer folk. A study published in the journal Life Sciences found that taking zinc supplements could increase leptin production in obese men by 142 percent! A half-dozen oysters only have 43 calories but provides 21 percent of your RDA of iron—deficiencies of which have been linked to a significant increase in fat gene expression.
The leafy green is jam-packed with energy-boosting nutrients such as vitamin A, iron, and folate. It can also reduce your appetite—helping to curb your calorie intake and encourage your body to start burning fat—thanks to natural compounds called thylakoids. Swedish researchers found that over three months, women who consumed a five-gram thylakoid supplement from spinach reported a 25 percent reduction in hunger and cravings and significantly more weight loss (11 pounds) than the control group!
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.
Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time without exercise. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a cherry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.
