Faux-sugars offer more than just zero calories—they decrease your metabolism, promote mood swings, and boost food cravings, which can ultimately up your daily caloric intake. Use a teaspoon of raw sugar, raw organic honey, or maple syrup instead. These all-natural options may have 15 to 20 calories, but they also don’t cause bloating or other digestive problems, plus you won’t have the urge to raid the office vending machine after your cup of tea.
