This is what's known as insulin resistance. Basically, when your body doesn't respond well to insulin, it actually makes more of the stuff, according to the National Institute of Diabetes and Digestive and Kidney Diseases. And that can lead to fat storage, especially around the middle of your body. That's where protein comes into play: A diet high in protein may protect you against insulin resistance, says Aronne.
The zero-calorie tag is particularly tempting when you’re desperate to drop fat, but honestly you’ll see better results if you avoid any artificial sweeteners in your diet. According to the Harvard School of Public Health, when your brain registers something as sweet but fails to get those calories associated with it, it causes your body to seek them elsewhere, leading to excess calorie intake. In addition, popular sweeteners like Splenda are 300-600 times sweeter than real sugar on average, and consuming them may send your sweet cravings through the roof, potentially leading to poor food choices. Steer clear of the fake stuff and reach for the real stuff in moderation if you absolutely need something sweet. However, if you’re really serious about getting rid of your excess fat it would serve you best to avoid added sugar at all costs.
Which means, sadly, the more glasses of rose and chocolate-coated pretzels you eat, the longer it will take to reach your flatter belly goals. “When you digest large amounts of calories, your body allocates some of these to functional systems which work to keep you alive (think the brain, muscles and organs),” says Belalij. “It also uses it to fill up energy stores. Any excess is then stored in fat cells around the body – typically being those of the belly.”
