It’s impossible to target belly fat specifically when you diet. But losing weight overall will help shrink your waistline; more importantly, it will help reduce the dangerous layer of visceral fat, a type of fat within the abdominal cavity that you can’t see but that heightens health risks, says Kerry Stewart, Ed.D., director of Clinical and Research Physiology at Johns Hopkins.
It makes scientific sense, also: A recent study found that antioxidants in cocoa prevented laboratory mice from gaining excess weight and actually lowered their blood sugar levels. And another study at Louisiana State University found that gut microbes in our stomach ferment chocolate into heart-healthy, anti-inflammatory compounds that shut down genes linked to insulin resistance and inflammation. Why the berries? The fruit speeds up the fermentation process, leading to an even greater reduction in inflammation and weight.
According to a recent article published by the Obesity Action Coalition, fad diets aren't for the faint of heart. Not only can they slow your metabolism, but they also increase the risk for gallstones, loss of lean body mass and malnutrition. Not to mention that you most likely will not lose weight fast or — even if you do drop a dress size — you'll most likely be unable to maintain your weight loss goals.
Carbohydrates are a touchy subject: while some blame them for all fat gain, it’s the type of carbs you eat that’s key. A 2011 study out of the University of Alabama found that a diet that slightly cut back on carbs, and which comprised mostly low-GI carbohydrates, lost more deep abdominal fat than those who ate a lower-fat diet. GI stands for glycemic index, a measure of how fast carbohydrates supply your body with energy: high-GI foods make you spike then crash, while low-GI foods provide a slow burn.
