Can I Drink Coffee During Intermittent Fasting?

You can have coffee during intermittent fasting but it has to be black, without any additives.

As we all know that coffee consists of mostly water as it is prepared by brewing coffee beans, thus, it contains a very minimal amount of calories that are unlikely to break your fast.

However, it is also true that not all coffee drinks are low in calories. The table below shows the calorie count in different coffee drinks.

Furthermore, coffee drinks that are consumed with dairy and sugar tend to be much higher in calories than plain black coffee. Therefore, you should avoid additives in your coffee during intermittent fasting.

However, you can add a small amount of cocoa, cinnamon, or almond milk if you don’t like plain black coffee.

Not every type of coffee can benefit you during fasting

Yes, it might be surprising for some people but coffee may enhance many of the benefits of fasting.

Metabolic Benefits

Some research also points out that higher coffee intake can be linked with reducing the risk of metabolic syndrome, which is an inflammatory condition characterized by excess body fat, high cholesterol, elevated sugar, and blood pressure.

Studies also link coffee with a reduced risk of type 2 diabetes. And that’s not all, up to 710 ml (3 cups) of coffee in a day is associated with a 19% reduced risk of death from heart disease.

Brain health

One of the main reasons why intermittent fasting has surged in popularity is its potential to protect against age-related neurological diseases and improve overall brain health.

Interestingly, coffee complements many of these benefits.

Just like intermittent fasting, regular coffee intake is also associated with a reduced risk of mental decline, as well as Parkinson’s and Alzheimer’s diseases.

While on a fast, your body uses its excess fats to produce energy in the form of ketones, a function related to improved brain function.

A study in mice linked coffee to significantly increased autophagy.

Intermittent fasting has also been observed to support brain health through increased autophagy, which helps your body to replace dead cells with healthy ones, the healthy brain cells ultimately protect against age-related mental decline.

Thus, it can be said that including moderate amounts of coffee in your intermittent fasting regimen can prove to be quite beneficial.

Black coffee can be the best choice if you are a coffee lover observing intermittent fasting. The reason is its negligible calorie content.

A cup of black coffee carrying all the antioxidant benefits of coffee contains even less than 5 calories. So you can surely enjoy black coffee during intermittent fasting.

Furthermore, if you are really in the need of that caffeine jolt but do not like to sip on a hot, bitter cup of plain black coffee, you can even go for a refreshing cold press or iced black coffee.

Both of these tend to be less bitter as cold water doesn’t extract as many of the acids from the coffee beans as hot water does.

Also, if you are someone with a sweet tooth or love having your coffee with different additives to make it tasty, then you can also go for coffee that is brewed from flavored beans.

These coffee beans are infused with different flavors so you may satisfy your urge for a flavorful cup of coffee without adding any calories that may break your fast.

All of these coffee drinks can be consumed during intermittent fasting as they carry a negligible number of calories while providing you with your much-needed caffeine fix.

Again, it is important to keep in mind that these drinks are only low in calories if you drink them black. 

Furthermore, the love for coffee shouldn’t let you forget that the benefits of coffee can only be reaped if it is consumed in moderation. Excessive intake can have unwanted side effects on your health.

Other Things To Consider During Intermittent Fasting

Though coffee tends to have positive effects on your intermittent fasting, make sure not to overdo it.

A single serving (around 240 ml) of coffee has about 100 mg of caffeine present in it. excessive consumption of caffeine from coffee could cause irreversible side effects to your body, including an increase in blood pressure and heart palpitations.

One study discovered that a high coffee intake of up to 3.1 liters (13 cups) in a day caused increased fasting insulin levels, leading to a short-term decrease in insulin sensitivity.

If your purpose of observing intermittent fasting is to increase your insulin sensitivity or improve your fasting insulin levels, you should be very much conscious about your intake of coffee.

Furthermore, excessive caffeine consumption could have adverse effects on your sleep quality. Poor sleep can harm your metabolic health over time, which could negate the benefits of intermittent fasting.

Most research indicates that up to 400 mg of caffeine in a day is safe to be consumed by healthy adults. This is equal to about 710–945 ml (3–4 cups) of regular coffee in a day.
