Do Intermittent Fasting and Coffee Work Together?

Intermittent Fasting and Coffee – Overview

Intermittent fasting is a type of eating habit that alternates between fasting and eating intervals.

To maintain your “fasted” and fat-burning condition, avoid consuming anything that may be utilized for energy (i.e. carbs, sugars).

Only low-calorie or zero-calorie beverages, such as black coffee, water, and tea, can be consumed during fasting.

In this post, we will discuss intermittent fasting and coffee, as well as its additions, such as milk and cream, and how this affects the effectiveness of intermittent fasting for weight loss.

Intermittent fasting and coffee

When fasting, it’s fine to drink a small amount of black coffee. Black coffee, in general, is unlikely to influence your metabolism or break your fast on its own.

Many influential health journals claim you will not break your fast if you consume less than 50–75 calories throughout each fasting window.

For example, one cup (240 ml) of black coffee has only 3 calories and very little protein, fat, or trace minerals, making it unlikely to cause a major metabolic change or break a fast.

Surprisingly, coffee may enhance many of the benefits of fasting

Consuming black coffee might maximize the advantages of fasting.

According to recent research, a frequent coffee habit has been linked to a higher mood, enhanced brain function, decreased risk of mental decline, and Alzheimer’s and Parkinson’s diseases.

Furthermore, drinking up to three cups of coffee per day has been associated with reduced inflammation, blood sugar levels, and the risk of heart disease, all of which contribute to a reduced risk of metabolic syndrome.

Also, dieters claim that black coffee helps to suppress your hunger, making it easier to stick to your diet and manage your fasting days.

Unfortunately, there is no scientific evidence to back up this claim.

Intermittent fasting and coffee with milk

Intermittent Fasting and Coffee

Intermittent Fasting and Coffee – With Milk

Milk contains around 5g of lactose and nearly the same amount of milk proteins in 100 ml.

Adding milk makes all the difference in coffee with intermittent fasting. Coffee with milk breaks the fast and diminishes the benefits of fasting.

When you add sugar, milk, or cream, the calories range from 16 to nearly 100.

While coffee may be a good way to feel like you’re eating something during your fasting hours, drink it black to keep your calories to a minimum.

Intermittent fasting and coffee with Almond milk

The bulk of store-bought almond milk has a lot of chemicals and sugars, which will almost likely disrupt your fast.

Pure almond milk, which is made up of only almonds and water, on the other hand, is perfectly safe in very low quantities.

Similarly, homemade almond milk is safe if no sugars are added. A splash of almond milk, or any nut milk, in your coffee, will not break your fast, but adding closer to 100 ml would most likely do.

Again, the effects of almond milk in coffee are negligible if you avoid sweetened or protein-enriched varieties and add a shot.

Intermittent fasting and coffee with creamers

A tiny quantity of creamer in your coffee seems OK and will not completely break your fast, but it may significantly change your blood sugar levels or overall calorie intake, slowing down your fat-burning state.

Heavy cream is preferred over low-fat dairy products when it comes to creamer.

Heavy cream, on the other hand, includes fat and protein and, if consumed in excess, might disrupt your fasting state.

For example, 1 ounce of heavy cream has just 1 gram of fat and 1 gram of protein, whereas some creamers might include up to 50% sugar.

Although consuming heavy cream does not necessarily inhibit fat burning, it can be a great addition to a ketogenic diet since it promotes autophagy in the long term.

What Can You Put in Your Coffee Without Breaking Your Fast?

Because it has no calories, black coffee is an excellent choice for an intermittent fast.

In reality, according to many health experts, a fast is not broken if you ingest less than 50 calories during the fast’s duration.

However, black coffee may not be your favorite beverage. You can drink coffee with the following components without breaking your fast:

  • A sprinkle of cinnamon
  • A touch of nutmeg
  • A teensy bit of cocoa
  • Low-calorie sweeteners


Anything high in calories, carbohydrates, or protein is generally considered a fast-breaker.

However, if you drink coffee in reasonable quantities, it won’t ruin your intermittent fast and may even benefit your health.

To minimize unpleasant side effects, it’s advisable not to consume too much coffee when fasting.

During a fasting window, drinking acceptable amounts of extremely low-calorie or zero-calorie liquids is unlikely to disrupt your fast severely.

Simply ensure that it is black and clear of any other chemicals.
