Odds are, you’ve probably heard of intermittent fasting by now. 

While fasting has long been done for religious reasons and medical ones, it recently become a popular method to improve health and lose weight. 

Touting it a a great way to limit calorie intake and increase insulin sensitivity, followers of intermittent fasting eat only within a certain time-frame to maintain a fasting period that's usually between twelve to sixteen hours per day. By maintaining a fasted state, people sometimes experience health benefits including improved heart health, reduced inflammation and better blood sugar control. But while many sing the praises of this eating method, it can sound quite daunting to the uninitiated.  

And if you love your morning cup of vanilla roast coffee, you might be wondering one big question. Does drinking flavoured coffee break a fast? 

The answer isn't quite as simple as it seems. It depends on a number of factors, including what type of flavoured coffee you enjoy, as well as anything else you might put in your cup.

Fasting for a Blood Test 

Before we get into the nitty-gritty of drinking coffee during intermittent fasting, it’s important to note that the circumstances are different if you are fasting for medical reasons, such as before a blood test. 

If you are fasting for a one-time blood test, it is typically advised to avoid coffee. 

Unless your doctor tells you otherwise, all drinks except water should be avoided. Of course, whether you need to fast or not will depend on what kind of blood work you’re having done, so make sure to check with your doctor about your specific situation. 

Intermittent Fasting and Coffee

Good news! You CAN fast and have your coffee too. When following the guidelines of intermittent fasting, plain black coffee is okay to drink while in your fasting state. 

However, any additional ingredients that contain sugar or calories can impact blood sugar levels, potentially causing your fast to be broken. 

Thankfully for coffee lovers, flavoured coffee containing flavouring as part of the brew is still considered ‘black coffee’ when nothing else is added. This includes vanilla, hazelnut and caramel roast. Generally, roasted beans are all-clear, but when using coffee pods, be sure to check whether they have any added sugar. 

See the diagram below to better understand what you can and can't add to cup of coffee while fasting. While natural sweetener with zero calories is okay, artificial sweeteners that contain sugar are not. Likewise, you should also avoid milk, heavy cream. If you really can't go without milk, a low-calorie low-sugar choice like unsweetened almond milk is the best option. 

Can add: 

• Cinnamon
• Cocoa powder
• Ice
• Vanilla Extract

Can't add: 

• Artificial flavours
• Sugar
• High-calorie additives (such as creamer or syrup) 

How Coffee Affects Fasting

According to Kim Foster, MD, ‘coffee without any added sugar, cream or milk is completely fine to consume during the fasting window. It does not significantly affect your body’s insulin level and it won’t break your fast.’

But what if you can’t stand it black? Is it okay to add some cream or coconut milk? Will it derail your fasting goals? According to Dr Foster, ‘some people say that a small amount of cream — since it’s high in fat — won’t trigger insulin or break your fast so it’s okay.’ Having spent a significant amount of intermittent fasting herself, however, she felt that the cream was disrupting her fast. Now, she only drinks black coffee while fasting — a habit that she attributes to weight loss and overall well-being. 

If you really love your morning cuppa and are saddened by the thought of giving up your favourite type of coffee, Dr Foster also has some great advice. Rather than nixing your favourite iced latte entirely, find a way to make it work with your intermittent fasting lifestyle. If Limiting your favourite milky or flavoured coffees to your eating hours will allow you to drink your coffee and enjoy it too! If this means you'll be drinking coffee later in the day, you. might consider trying decaf coffee to avoid disruptions to sleep and circadian patterns.
