If you’ve heard a lot about “intermittent fasting” recently, you’re probably wondering what’s so popular about the latest dieting trend. There was Atkins and South Beach, then came keto and paleo—so how’s this one different?

Well, intermittent fasting isn’t so much a “diet” because there aren’t restrictions on what you can eat. Fasting is more a pattern of eating that uses hard-and-fast rules to guide when you eat for weight loss or control. While there are various routes to take like alternate-day fasting and periodic fasting, where you skip food for a day (or days) or randomly through the month, basic daily fasting is a popular option. See how much you know about how this time-focused eating works—and how it may affect your health.
