Healthily curbing your midafternoon cravings is that much harder when your options are limited to a vending machine. Sure, not all of its choices are bad, but most are calorie bombs—empty calories at that, so in addition to feeling guilty, you’re also still hungry. A general rule of thumb is to always snack on something that combines moderate calories with the ability to satisfy your hunger. And avoid empty-calorie foods like cookies and candy. This way, you won’t ditch your diet and are less likely to overeat during your next meal. Here, your no-gain guide to your office’s vending machine.
