Core exercises will strengthen your abs, but they won’t eliminate the fat that lies beneath them. To do that, you have to ramp up your overall calorie burn with cardio (running, walking, biking). A Duke University study found that people who did moderate cardio for 178 minutes per week (roughly 30 minutes of walking six days per week) gained hardly any visceral fat over the course of eight months. Participants who worked out at a higher intensity (jogging) for a similar amount of time saw even better results — reducing their belly fat by almost 7 percent. To maximize your workout, try interval training, which alternates between high- and low-intensity cardio.
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.
Don’t buy your tickets to Bonnaroo just yet; the kind of acid that will help you slim down is the stuff right inside your cabinet. A 12-week study published in Bioscience, Biotechnology, and Biochemistry reveals that obese study subjects who made vinegar part of their diet dropped more belly fat than a control group, and other research suggests that acidic foods, like vinegar, can increase the human carbohydrate metabolism by as much as 40 percent.
The traditional hot-dog topping can do serious wonders for your waistline. "Fermented foods like sauerkraut, pickled veggies, and kimchi are some of the best sources of probiotics — a form of good bacteria that support healthy digestion and decrease bloat," says Frank Lipman, M.D., founder of Eleven Eleven Wellness Center in New York City. "That's important, since diets low in probiotics can cause bad bacteria to overtake the good ones, leading to health problems ranging from autoimmune diseases to weight gain."
“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.”
