Can I Have A Ristretto While Intermittent Fasting?

Can you have one while intermittent fasting?

The answer is yes. You can have a ristretto while practicing intermittent fasting.

Intermittent fasting involves alternating between periods of eating and fasting to promote weight loss and improve overall health.

During the fasting period, it is recommended to consume zero or minimal calories.

A ristretto is a concentrated form of espresso that contains less water but retains all the flavor and caffeine content.

It typically has fewer than 20 calories per serving, making it an acceptable choice during your fasting window.

However, it’s important to note that adding milk or sugar would break your fast as they contain calories and can trigger an insulin response.

Can I Drink A Ristretto While Fasting?

Enjoy a ristretto without worrying about breaking your fast if you’re fasting. A ristretto is a concentrated form of espresso made by extracting less water through the coffee grounds. It contains less caffeine and fewer calories compared to regular espresso or coffee.

Since ristrettos are low in calories and do not contain any significant amounts of protein, carbohydrates, or fat, they do not cause an insulin response or impact your fasting state. Some experts believe that the polyphenols found in coffee may even offer health benefits during fasting periods.

However, it’s important to note that adding cream, sugar, or any other calorie-containing ingredients to your ristretto will break your fast. So if you prefer your ristretto plain or with a dash of cinnamon or nutmeg for flavoring, feel free to indulge while maintaining your fasting goals.

How Does A Ristretto Impact Fasting?

Following specific guidelines for accurate results is important regarding bloodwork or glucose tests. Drinking any beverage, including a ristretto, can interfere with the fasting requirement before these tests.

To ensure the most reliable and precise results, it is recommended that you strictly adhere to the fasting instructions provided by your healthcare professional before undergoing bloodwork or a glucose test.

For Bloodwork

Having bloodwork done? Don’t worry. A ristretto won’t affect your fasting.

Regarding blood tests, fasting is often required to get accurate results. Fortunately, a small cup of ristretto won’t break your fast and interfere with the accuracy of your test. Here are some reasons why you can enjoy that rich and flavorful ristretto before heading to the lab:

  • Ristretto is made by extracting less water from the coffee grounds, producing a concentrated flavor without adding significant calories or nutrients.
  • It contains minimal carbohydrates and fats, so it won’t spike your insulin levels or disrupt metabolic processes during fasting.
  • The caffeine content in a ristretto can improve alertness and focus while waiting for your bloodwork appointment.
  • Enjoying a ristretto can provide a comforting ritual and sense of belonging while navigating the challenges of fasting for medical purposes.

For Glucose Test

Don’t worry, a small cup of ristretto won’t affect the accuracy of your glucose test. Regarding fasting for a glucose test, the focus should be on avoiding food or drinks that contain sugar or carbohydrates.

Ristretto is an espresso that extracts less water through finely ground coffee beans. It contains minimal sugar and carbohydrates, making it unlikely to significantly impact your blood glucose levels.

If you don’t add any sweeteners or milk to your ristretto, it should not affect your glucose test results. However, if you have any concerns or specific dietary restrictions from your healthcare provider, it’s always best to consult them beforehand for personalized advice.

Pros and Cons of Drinking Ristrettos During Fasting

If you’re fasting, weighing the pros and cons of drinking a ristretto is important. Here are some points to consider:


  • Intense flavor: A ristretto is highly concentrated, delivering a bold and rich taste that can be satisfying.
  • Lower caffeine content: Compared to a regular espresso shot, which contains around 63 milligrams of caffeine, a ristretto typically has less caffeine due to its shorter extraction time.
  • Faster energy boost: The concentrated nature of a ristretto means that the small amount of coffee consumed can provide an immediate burst of energy.
  • Enhanced focus: Combining flavor and caffeine in a ristretto may help improve mental alertness and concentration.


  • Potential hunger stimulation: Some individuals find that drinking coffee on an empty stomach can increase feelings of hunger during fasting periods.
  • Digestive issues: Coffee can have a laxative effect on some people, leading to potential discomfort or disruptions during fasting.
  • Interference with autophagy: Fasting promotes cellular repair through autophagy. Studies suggest that consuming anything other than water may disrupt this process.
  • Individual variations: It’s important to note that everyone responds differently to coffee consumption during fasting. Personal experimentation is essential in determining how your body reacts.

Whether or not to drink a ristretto while fasting depends on your personal goals and preferences.


So, should you have a ristretto while fasting? Ultimately, the choice is yours.

While some argue that it may break your fast due to its concentrated flavor and potential impact on insulin levels, others believe its minimal calorie content allows it to be enjoyed without disrupting your fasting period.

Consider your specific fasting goals and consult with a healthcare professional if needed.

Everyone is different, and what works for one person may not work for another.
