Can I Drink Coffee While Fasting

Can I Drink Coffee While Fasting is Okay? You’re not alone. Millions of people around the world practice intermittent fasting for various reasons. Whether it’s for weight loss, health benefits, lifestyle choice, or something else altogether, there are many related questions—including whether or not you can drink coffee while fasting. 

This guide will provide some facts and tips on what to consider when drinking coffee while fasting. Read on to learn more and determine if it’s the right choice. 

When you fast, your body is burning stored energy, which means that adding cream or artificial sweeteners to your coffee can interfere with this process. In addition, cream and artificial sweeteners can affect blood sugar levels, disrupting fasting.

The Science Behind Coffee Fasting 

Like any other beverage, coffee contains calories—but that doesn’t mean it can’t be incorporated into a successful fast. Studies have shown that drinks containing fewer than 50 calories don’t affect the body’s insulin response and can therefore be consumed during a fast without breaking it. 

That means that a cup of black coffee—which usually contains between 0-5 calories depending on the size and preparation method—is an ideal choice for those looking to incorporate caffeine into their fasts, as it won’t interfere with achieving ketosis. 

Drinking Coffee While Fasting: The Pros and Cons

Like anything else, there are pros and cons to drinking coffee while fasting. Before you decide on your approach, it’s essential to understand both sides of the argument. 


  • You can have your morning fix of caffeine without breaking the fast. 
  • Coffee can help suppress your appetite and make fasting easier. 
  • It may help boost energy levels and keep you focused during a fast.


  • Some people might experience side effects such as jitters or irritability due to their sensitivity to caffeine. 
  • It’s not recommended for those with some health conditions, such as high blood pressure. 
  • It might not be easy to measure the amount of calories you’re consuming, which could affect your fast.

Tips for Safely Enjoying Coffee During Fasting 

If you decide that drinking coffee during a fast is right for you, here are some tips to help ensure it’s done safely and effectively: 

  • Make sure you stick to black coffee with no added sweeteners or creamer. 
  • Avoid making coffee your primary source of hydration during a fast – it’s also better to drink plenty of water. 
  • Monitor your feelings throughout the day and adjust your caffeine intake accordingly. 
  • Start with a smaller amount of coffee and increase it gradually to avoid any unpleasant side effects. 
  • Avoid sugar-free alternatives such as artificial sweeteners, as they may contain enough calories to break your fast. 

Can I drink coffee with sugar during intermittent fasting? Drinking coffee with sugar during intermittent fasting is not recommended, as sugar contains enough calories that could break your fast.

 If you’re looking for an alternative sweetener, opt for a low-calorie option such as Stevia or Monk Fruit, but keep in mind that consuming any calorie can interfere with the effects of the fast. Additionally, be mindful of how much you’re consuming, as over-sweetening your coffee could lead to other health risks. 

Coffee with Additives while Fasting

 It may be a no-go, but you must enjoy your favorite flavors. If you’re looking for something more palatable, plenty of delicious tea options can give you the same energy boost without interfering with your fast. Green tea is one of the most popular choices because it contains antioxidants, boosts metabolism, and has been linked to numerous health benefits. 

Herbal teas like chamomile and ginger can also provide an added boost of flavor without calories or caffeine. 

In addition, there are many sugar-free coffee mixes and syrups you can add to your black coffee to get a sweeter taste without compromising your fast. Some popular options include coconut milk, almond milk, oat milk, and sugar-free syrups such as vanilla or hazelnut. 

Overall, it’s important to remember that moderation is key when drinking coffee while fasting. Stick within the recommended guidelines and pay attention to your body to find the right balance for your needs.

Expert Opinions

Expert opinions on coffee during fasting can vary, so it’s essential to take the time to research and consider what makes sense for your goals. As with any lifestyle choice, speaking with a qualified healthcare professional before changing your diet or fasting routine is best. 

At the end of the day, whether or not you should drink coffee while fasting is up to you—but if it’s something you choose to do, understanding your body and being mindful of the potential risks is vital. 

With a few precautions, drinking coffee during fasting can be a great way to fix your morning caffeine and reap the benefits of intermittent fasting.


Does coffee break your fast?

Whether or not coffee breaks your fast depends on the type of fast you’re doing and the ingredients contained in your cup. Generally, a cup of black coffee will not break fast as it has no calories. However, adding milk, creamers, or sugary additives to your coffee can raise calorie content enough to break your fast.

Can you have coffee with milk while fasting?

The short answer is that you can have coffee with milk while fasting. However, it’s important to note that adding milk or creamers to your coffee will increase the calorie content and may break your fast, depending on your fasting protocol.

If you choose to add milk, opt for a low-fat version and monitor your intake to ensure you’re still staying within the calorie limit of your fast. Additionally, try alternative milk, such as almond or oat, for a dairy-free option.
