Science backs these ideas up when it comes shedding belly fat: In one study published in The Journal of Nutrition, researchers had overweight men and women follow a high-protein diet (30 percent protein, 40 percent carbs, and 30 percent fat) or a high-carb diet (15 percent protein, 55 percent carbs, and 30 percent fat). After one year of weight loss and maintenance, they found that the high-protein group experienced a 21 percent greater weight loss and 27 percent greater body fat loss on average than the high-carb group.
A 2012 study in the Journal of Functional Foods found that people who drank one and a half cups of green tea enriched with a total of 609 milligrams of catechins (a group of antioxidants that have been shown to help burn fat cells) every day for 12 weeks lost almost 16 times as much visceral fat as those who consumed green tea without the added antioxidants. To achieve similar results with store-bought green tea, you’ll need to brew two to four cups daily (many varieties can contain 160 to 470 milligrams of catechins per cup).
“Include lots of nutrient-rich vegetables, a source of protein and some healthy, unprocessed carbs,” says Belalij. “Start with leafy greens such as spinach, kale and collard greens, then add carrots, broccoli and peas. Lean meats, including turkey and chicken, are ideal as they are lower in fat and therefore calories, or, if you are vegetarian/vegan, add in tofu or a handful of nuts such as pine, cashew or almonds and a sprinkling of seeds (sunflower, sesame, pumpkin). When it comes to carbohydrates, rice, quinoa and potatoes are perfect.”
