Green tea. Studies have shown that regular consumption of green tea can moderately promote weight and fat loss. The secret to green tea’s fat-burning power is its catechins, the antioxidants in tea that combat free radicals and promote healthy cells. One cup of green tea contains between 50 to 100 milligrams of catechins, and most research shows that you must drink about five cups of green tea every day to see a fat-burning effect.
“It can’t hurt if you just sip it all day,” Jillian says. “It keeps you hydrated, and you get all those antioxidants and their cancer-fighting effects.”
Omega-3 fatty acids. A daily dose of omega-3-fatty acids, whether through a supplement or a natural source such as salmon, boosts weight-loss efforts when combined with exercise more than exercise alone, a study at the University of South Australia found. Researchers say this is because omega-3s are polyunsaturated fats that can boost fat oxidation, but that exercise is also required to reap this benefit. Studies have shown that just a few servings of fish per week can help with fat loss in lieu of supplementation.
Pistachio nuts. The simple act of swapping pistachios for your other favorite salty snacks has been shown to produce weight loss, with no additional effort required. A recent study also demonstrated that pistachios can improve symptoms of metabolic syndrome, such as blood pressure, insulin levels, and blood glucose levels.
“The other thing about pistachios is that it takes a while to open them up, and it’s going to slow your eating down,” Jillian says. “You’re not going to house a giant bag of nuts like you would chips.”
Pomegranate. Both pomegranate and pomegranate oil have been shown to help burn fat in overweight people and reduce inflammation in the body, which can lower risk for heart disease and cancer. Some recent studies have even found that eating pomegranates may help prevent obesity and diabetes in both mice and humans.
