Fiber works its weight loss magic in multiple ways. It helps you feel fuller, longer so eating fiber-rich foods is the dieting equivalent of working smarter, not harder. Plus, fiber takes a long time to digest, so fiber-rich foods don’t cause spikes in blood sugar that can send your insulin levels soaring. On the other hand, when you eat the so-called bad carbs (the refined or sugary ones that lack fiber), you may wind up with an insulin response that promotes fat storage. The takeaway: More fiber equals less fat storage.
Many people chew gum as a way to stifle cravings or prevent mindless eating but this tactic may have an unfortunate side effect: belly bloat. Everyone naturally swallows a small amount of air when they chew but it’s magnified for people who chew gum, which causes gas and bloating. In addition, some artificial sweeteners have been shown to increase your appetite for junk food, so gum could be increasing your waistline on two fronts.
