Intermittent fasting is one of the most popular dietary trends of the moment. Whether you follow the 5:2 plan or prefer the 16:8 pattern, it’s easy to see why this way of eating can be so appealing. With fewer rules than other nutrition plans and a simple structure, it can be a great way to help with weight loss and improve overall health.¹

While intermittent fasting is quite simple, there are some rules you need to stick to for it to work correctly. Whichever plan you follow, the fasting window restricts your food intake. That means you generally won’t eat anything until it’s time to refuel with a healthy meal. That’s pretty clear, right? What isn’t so clear is how drinks affect your intermittent fast and whether there are certain fluids you should avoid. Plus, it’s not always easy to know the best way to break a fast. Here are some tips to help you get the most out of your intermittent fasting plan.
