Fasting For Coffee And Health

Can You Drink Black Coffee While Fasting? (It Depends! Here’s WHY)

As you can see, tea and coffee during fasting are great for not only stopping yourself from feeling hungry but they also boost the effectiveness of your fast by a lot.

Whatever the case may be, fasting, as well as coffee by themselves, are great for your health but combining them can be even better. You just have to take everything in moderation and be mindful of your bodys conditions.

What Can I Put In My Coffee That Won’t Break A Fast

Now that we know that our favorite creamer is off the table while were in the middle of a fast, is there any way to flavor our coffee that wont interfere?

For most people, the best way to do this is with an artificial sweetener. Choose something like Stevia or monk fruit that provides sweetness without calories or sugar. Many prefer these over other artificial sweeteners like aspartame because theyre more natural.

If sweeteners arent your thing, a sprinkle of cinnamon only gives a hint of flavor, but could still do the trick.

Benefits Of Flavored Coffee Beans While Intermittent Fasting

Coffee, in any form, is an appetite suppressant, so it helps to make intermittent fasting a little easier.

If youre fasting to manage blood sugar, coffee is also great to have. One study showed coffee is associated with better insulin sensitivity. However, intermittent fasting, in general, has the same benefit, so if youre only an occasional coffee drinker, you dont have to start having it daily.

Another study showed coffee triggered autophagy in mice. While we need more studies to say for certain if this effect happens in humans as well, the results are promising for those who fast for autophagy.

If the coffee youre drinking was flavored during the roasting process and has only natural ingredients, you will get all these benefits by drinking it. Also, flavored coffee could help curb your sweet tooth, which can be extremely helpful during a fast.

Can You Have Your Coffee With Cream Or Sugar On A Fast

However most people dont drink your coffee black. Some add creamer or milk. Others add sugar or sweeteners.

The answer is, it depends on how dogmatic you want to be about fasting.

If we are only talking about nutritional intermittent fasting, we really want to avoid adding anything to our coffee that would either increase our blood sugar or cause insulin levels to rise.

If youre adding a splash of heavy cream, which is mostly fat and very little sugar then youre not going to see a noticeable change in your blood sugar. So that splash of heavy cream to your coffee wont break your fast.

However, be careful if youre getting your cream added at a coffee shop like Starbucks. Their cream is actually half-and-half, which is half cream and half milk. Milk does have some sugar in the form of lactose, and if you add enough half-n-half to your coffee, you may cause and increase your blood sugar and that would break your fast. Adding in skim, 2%, or whole milk to your coffee would also potentially increase blood glucose levels from the sugar in milk.

So be careful of adding too much cream or milk to your coffee while intermittent fasting.

What about sugar and artificial sweeteners and nutritional sweeteners?

Regular table sugar is going to have some impact on your blood glucose and insulin level, so sweetening your cup of java with regular sugar would break your fast.

Bulletproof Coffee Offers Benefits For Keto And Intermittent Fasting

Can You Drink Coffee While Fasting?

In my opinion, Bulletproof Coffee can stimulate metabolism and performance.

Accordingly, the powerhouse of nutrients from grass-fed butter and MCTs from coconut oil is enjoying great popularity.

If prepared correctly, keto coffee can help to burn more fat. Also, its ideal for starting intermittent fasting or a ketogenic diet.

Nevertheless, at some point, it is time to write off the training wheels. If you have been 16/8 intermittent fasting for some time, you wont need additional energy supply in the morning anymore.

Then it is no longer necessary to enrich your coffee with fat as an energy source.

Accordingly, I use Bulletproof Coffee somewhat depending on the situation. If there is no time for a meal, Bulletproof Coffee can help you feel satiated, energized, and focused in no time.

Nevertheless, many people do not want to miss it in their everyday life. Because the mixture from Ghee and MCT oil does not only taste delicious, it also supplies extremely high-quality fatty acids.

However, also experienced keto dieters and fasting enthusiasts can benefit from the satisfying and energizing effect of Bulletproof Coffee again and again.

For example, when they start a new intermittent fasting schedule like One Meal A Day .

One Final Suggestion And Its Up To You

Believe it or not, the Leangains protocol says its OK to drink diet soda while fasting. Yes, diet soda. What is this heresy?

Other IF plans call for clean eating with a complete ban on processed foods. Diet soda is about as processed as these trap vocals.

Lets put diet soda in the maybe column. One every now and then wont kill you or mess with your diet too much.

The Health Benefits Dont Stop There

Drinking coffee while fasting could positively affects mental and physical performance. Many people are hesitant to exercise while fasting, but coffee on a fast may be helpful here as well.Zach Bitter, an ultramarathon runner, and coach at Zach Bitter Running is a fat adapted athlete who has competed in over 40 ultramarathon competitions. One of his notable accomplishments includes running 100 miles in an American record of 11 hours, 40 minutes and 55 seconds.

During a recent interview with me, Zach admitted he doesnt like to eat when training. He prefers to work out in the morning, and instead of eating, will have coffee on a fast with coconut or almond milk, and a bit of raw honey. He goes on to say:

Then Ill go out, and Ill train hard for a couple hours, sometimes over three hours. At that point, if I slept eight, nine, ten hours the night before and ate dinner at a normal time, by the time I could get back, Ive metabolized enough calories to almost put together a fast of over 24 hours. I think just by that lifestyle, you get really fat adapted.

What Is Bulletproof Coffee

Bulletproof Coffee, also known as butter coffee or keto coffee, is an energizing drink made from high-quality fats and fresh coffee.

Hence, the classic Bulletproof Coffee recipe consists of:

  • Coffee
  • Coconut or MCT oil

MCT stands for medium-chain triglycerides, a type of fat that is extracted from coconut oil.

This Bulletproof Coffee recipe is a recipe developed and protected by the bio-hacker Dave Asprey. In recent years, however, a variety of high-fat, sugar-free coffee varieties have developed.

Because this buttery coffee provides energy, reduces appetite, and fosters ketosis a metabolic state in which the body burns fat as its primary source of energy is very popular.

In case you want to try Bulletproof Coffee, you can easily prepare it at home. Although there are instant products, I would advise against it and stick to the natural Bulletproof Coffee recipe.

If you drink Bulletproof Coffee instead of a high carbohydrate breakfast, you will feel full and energized for hours. Thats why its an excellent tool to help jump-start intermittent fasting and the ketogenic diet.

Intermittent Fasting: Coffee With Creamer

Does Coffee Break A Fast? [Can You Drink Coffee While Intermittent Fasting?]

Creamer and similar additives in powder form are highly processed. Therefore, these are absolute junk!

They are loaded with carbohydrates, proteins, and fat. Moreover, some creamers consist of up to 50% sugar.

Also, coffee with sugar-free creamer isnt an option. Besides too much protein and fat, you will find other artificial additives like sweeteners in it.

If you like your body, you should avoid these junk additives not only during fasting.

Don’t Miss: What Are The Best Fasting Diets

What If I Accidentally Eat Or Drink Before My Blood Test

If you have been instructed to fast before your blood test and you accidentally eat or drink something during the fasting window, it is important to notify your healthcare provider or the person drawing your blood. If you dont, your results could be incorrectly interpreted.

It may be possible for your healthcare provider to interpret the non-fasted test results. Most likely, they will instruct you to reschedule the blood test at a time when you will be able to successfully complete the fast before the test.

Your physician will let you know the steps you need to take before your blood test, including whether or not fasting is required and for how long. By following all testing instructions and best practices , you can ensure a smooth testing process and the most accurate results.

Bulletproof Coffee With Coconut Oil Or Mct Oil

MCT stands for Medium-Chain Triglycerides. These are medium-chain fatty acids that occur mainly in coconut oil.

Therefore, pure MCT oil is derived from coconut oil but contains a higher concentration of MCTs.

Since exceptionally high-quality MCT oils consist of Caprylic acid , which is only eight carbon atoms long, these can be metabolized faster than ordinary coconut oil.

Hence, MCT oil can be four times as effective as coconut oil when it comes to ketone production. As a result, most people report increased mental focus after drinking Bulletproof Coffee.

In this sense, there is a difference between regular coconut oil and MCT oil when talking about energy boost and weight loss.

Nevertheless, coconut oil contributes to the well-known benefits of Bulletproof Coffee.

Regular Coffee Or Decaffeinated Coffee Which Is Better For Fasting

The effects of coffee during your fasting window really depends on the state of your hormones. While coffee in general can be anti-inflammatory, drinking too much caffeine wont benefit your metabolic health if you display signs of adrenal dysfunction.

Some signs of adrenal fatigue include:

  • Brain fog
  • Cravings for sweet and salty foods
  • Poor stress response and mood regulation
  • Feeling fatigue throughout the day, especially upon waking

If you display these symptoms while following a keto and intermittent fasting lifestyle, adding even more stress to the equation with too much caffeine intake is bad news bears.

Cutting most carbs out of your diet with a ketogenic diet is a stress to your body. This is especially true if your digestive system isnt up to par when adding more fat and protein to your meal plan.

Going long periods without food, aka intermittent fasting, is also a stress to your body.

While these stressors can be an effective way to burn fat for many, if you also display signs of adrenal fatigue and then add too much coffee on top of this, all three of these combined can create levels of stress hormones that are out of control. AKA you wont lose weight. And youll feel pretty bad on top of it!

Bulletproof Coffee During Fasting

Can you Drink Coffee While Intermittent Fasting?

That doesnt go to say those other coffee beverages you can get from Starbucks or cafes wont not only kick you out of a fasted state but will also make you gain weight. Of course, adding milk, sugar, caramel, spices, or other calories will stop the beneficial effects of a fast.

The same applies to things like Bulletproof coffee or adding coconut oil to your beverage in hopes you can trick your brain.

To maintain autophagy and increase AMPK, you need to suppress mTOR. Fat doesnt raise insulin and it keeps mTOR suppressed in small amounts. Endogenous ketone bodies from your own body fat will stimulate autophagy, which can promote brain macroautophagy as well.

However, high amounts of ketones and fat in the blood can also make you raise insulin. If theres too much energy circulating around in the body, then thats a signal to stop autophagy and trigger mTOR.

Exogenous ketones can also be insulinogenic.

In a study done on rats, they found that exogenous ketones promote insulin secretion when blood glucose was greater than 5.0 mMol/L or 90 mg/dl. If youre a healthy person who is very lean and low on body fat, then your blood glucose will probably drop below that. If you already have excess energy stored in your body fat then its a signal that theres plenty of energy already around and any form of calories, whether that be from Bulletproof coffee or exogenous ketones will most likely inhibit autophagy.

Drink Tea And Coffee During Fasting

If you experience these negative side-effects of caffeine by becoming too anxious or stressed out, then you can take some l-theanine with caffeine.

Theanine is an amino acid thats found in green tea and if you combine these two you create incredible synergy.

  • Caffeine is great for concentration, attention span, and focus. Its downside is elevated heart rate, blood pressure, and anxious/jittery feelings.
  • L Theanine is a relaxing compound that can lower heart rate and blood pressure, promote alpha brain waves and avoid the jitters.

Combining caffeine and l-theanine can actually boost the effects of caffeine alone.

You take L-theanine supplements with your coffee or you can simply drink regular green tea as well as it contains l-theanine. In fact, green tea is another amazing beverage for fasting. It has polyphenols and other ingredients like epigallocatechin-3-Gallate that stimulate autophagy

Youll get a better and more long-lasting energy response by drinking coffee and sipping on your green tea at the same time.

How Does Intermittent Fasting Work

The idea behind fasting is that when you eat regularly throughout the day, your body burns the calories youre consuming and stores the extra calories as fat. The intermittent fasting theory goes that if you restrict your eating to a set number of hours, your body will have to switch to burning your stored fat in the off-hours. This is called metabolic switching, and some believe it can help you lose weight.

Nutrition-wise, there isnt a lot in coffee. There are only a couple of calories and minimal amounts of protein and fat in a cup of coffee. That means that drinking coffee wont significantly affect your metabolism. Though you may feel like coffee gives you an energy boost, its not the same as consuming calories. Drinking a cup of coffee wont cause your metabolism to switch back to burning sugar because it doesnt contain any.

Can I Drink Coffee / Alcohol / Juice / Soda / Tea While Fasting

Can You Drink Bulletproof Coffee While Fasting?

No. Any beverage other than water should not be consumed before a blood test, unless approved by your healthcare provider. Alcohol, soda, and juice contain high quantities of sugar, which can interfere with many common test results.

Black coffee, tea, and other caffeinated beverages are diuretics, which can have a dehydrating effect and cause test results to be inaccurate. For best results, avoid drinking all non-water beverages for the recommended amount of time before your test.

Coffee And Weight Loss

Coffee drinkers are maintaining their weight over the long term more efficiently .

The fact that coffee reduces appetite could be a good reason for this .

Also, coffee increases the metabolic rate. Hence, coffee is particularly beneficial for weight loss .

Therefore, the combination of coffee and intermittent fasting can help you to stay fasted longer and lose weight quicker.

What Happens In The Body During Intermittent Fasting

During the fasting period, few or no calories are consumed which causes insulin levels to drop. The body will then begin to use stored glucose for energy. Once glycogen stores are used up, the body may begin to burn fat for fuel . This can result in minor weight loss which is often one of the primary reasons why one may practice intermittent fasting.

In addition to some of the weight loss benefits, intermittent fasting may also induce cellular repair, reduce inflammation and improve insulin sensitivity. Some animal studies have also shown that intermittent fasting may promote anti-aging and play a role in cancer prevention. However, more human research is needed to confirm these findings.
