Do you love starting your day with a creamy latte but worry it might break your fast? Well, fret no more! We’ll explore the age-old question: Does a latte break a fast?

By delving into the scientific evidence and examining the pros and cons, we aim to provide practical insights on whether enjoying that frothy goodness during your fasting window is viable.

So grab your favorite mug, and let’s dive in!

Can I Have A Latte While Intermittent Fasting?

Can you have one while intermittent fasting? The answer is not a simple yes or no. While black coffee and plain tea are generally accepted as non-caloric beverages that won’t break your fast, adding milk or sugar to your drink can affect the fasting state.

A latte typically contains milk, which adds calories and carbs to your beverage. Consuming calories during the fasting window can disrupt the metabolic benefits of fasting, such as increased fat-burning and improved insulin sensitivity. However, if you’re following a more flexible form of intermittent fasting, like the 16:8 method, having a small amount of milk in your latte may not completely derail your progress.

It’s important to consider individual goals and preferences when deciding whether or not to include a latte in your fasting routine.

Can I Drink A Latte While Fasting?

No, you cannot drink a latte while fasting.

However, you may enjoy a latte during fasting if you make a few adjustments. While traditional lattes contain milk and sugar, some alternatives can be more suitable for fasting. Here are some options to consider:

  • Almond Milk Latte: Made with almond milk instead of cow’s milk, this latte is lower in calories and carbohydrates.
  • Coconut Milk Latte: Coconut milk adds a creamy texture and flavor without the added sugars in regular lattes.
  • Black Coffee with Steamed Milk: Adding a small amount of milk to your black coffee can provide a similar taste experience without breaking your fast.
  • Matcha Latte with Unsweetened Almond Milk: Matcha is a powdered green tea that offers health benefits and can be made into a delicious latte using unsweetened almond milk.

How Does A Latte Impact Fasting?

Regarding bloodwork, especially for a glucose test, following fasting guidelines is important. Consuming anything other than water can potentially impact the accuracy of your results. Even a small latte or any food and drink containing calories can stimulate insulin release and affect your blood sugar levels.

Therefore, avoiding consuming anything other than water before undergoing bloodwork or a glucose test to ensure reliable results is best.

For Bloodwork

If you’re getting bloodwork done, avoiding consuming a latte during your fasting period is important. While a latte may seem harmless, it can impact the accuracy of your blood test results.

Here’s why:

  • Caffeine: A latte contains caffeine, which can affect certain blood markers like glucose and cholesterol levels.
  • Sugar: Many lattes are sweetened with sugar or syrup, causing an increase in blood sugar levels that may interfere with your test results.
  • Milk: Lattes are made with milk; dairy products can alter lipid profiles and liver function tests.
  • Fats: Lattes often contain high-fat milk or added cream, which can impact triglyceride levels.

To ensure accurate bloodwork results, stick to water or black coffee during fasting. It’s better to be safe than sorry when getting reliable information about your health.

For Glucose Test

For accurate glucose test results, avoiding consuming anything other than water or black coffee during your fasting period is important. This means that you should refrain from having a latte before your test.

While a latte may be delicious and boost energy, it contains ingredients that can affect blood sugar levels. The milk in a latte contains lactose, a sugar that can raise blood glucose levels. Additionally, flavored syrups or sweeteners added to lattes can increase blood sugar.

To ensure the most accurate results for your glucose test, stick to water or black coffee only during fasting. This will help accurately reflect your body’s true glucose levels.

Pros and Cons of Drinking Lattes During Fasting

Drinking a latte during fasting has its pros and cons. Let’s consider the following points to help you make an informed decision:

  • Convenience: A latte can be a quick and easy way to fix your caffeine while fasting, especially if you’re on the go.
  • Flavor: Lattes come in various flavors, allowing you to indulge in something tasty during fasting.
  • Energy boost: The caffeine in lattes can provide a temporary energy boost, which may be helpful if you’re feeling sluggish during your fast.

Potential drawbacks – Lattes often contain added sugars and milk, which can break your fast by raising blood sugar levels.

While drinking a latte might seem appealing, it’s important to understand that it could potentially disrupt the benefits of fasting. Ultimately, the choice is yours based on your individual goals and preferences.


In conclusion, while the choice to have a latte during fasting ultimately depends on your specific goals and preferences, it is important to consider its impact on your fast.

On one hand, lattes can provide energy and satisfaction, making fasting more manageable. However, they also contain calories that can break your fast and potentially hinder weight loss efforts.

It is crucial to weigh the pros and cons before indulging in a latte during fasting to ensure you stay on track with your goals.
