Fasted Body on Coffee and Intermittent Fasting

Table of Contents

Many individuals are interested in whether fasted body on coffee is your way to go during fasting periods as intermittent fasting becomes more popular. 

Everyone loves coffee, right? Well, maybe not everyone. If you prefer to steer clear of coffee in the morning and after your workouts, don’t worry– I won’t try to persuade you otherwise. But for most people, coffee is an excellent way to start the day or help get through an afternoon slump.

The efficacy of fasting has been known for thousands of years, dating back to ancient civilizations around the globe. In recent years, some research has turned its attention toward understanding whether fasting could be useful in conjunction with exercise. The results have been promising: many studies have shown performance benefits from intermittent fasting when paired with resistance training (RT). However, none have looked at combining intermittent fasting with high-intensity interval training (HIIT)—until now!

If you’re interested in intermittent fasting, you already know the basics. You might be wondering if coffee can help or hinder your fast, and if it does, can it boost the effects of intermittent fasting? And what about an additional cup of coffee? Does that break your fast too? Read on to learn how coffee can help (or hurt) your results from intermittent fasting!

What Is Intermittent Fasting?

What Is Intermittent Fasting?

Intermittent fasting is the process of alternating between periods of eating and fasting. It can be done by restricting calories or involving time-restricted feeding, which means eating only during a specific window every day. In addition to these two common methods, there are other types of intermittent fasting.

The benefits of intermittent fasting include:

  • improved insulin sensitivity and brain health;
  • decreased risk for diabetes, cancer, cardiovascular disease, and Alzheimer’s disease;
  • increased muscle mass—which may help prevent age-related muscle loss;
  • reduced inflammation throughout the body;
  • increased longevity in animal studies (although similar effects have yet to be proven in humans);
  • higher levels of human growth hormone (HGH);
  • enhanced moods; and
  • lower stress levels caused by chronic exposure to insulin over time (insulin resistance).

The types of IF range from skipping breakfast one day per week up to not eating anything at all for 20 hours every day!

Can you drink coffee while intermittent fasting?

The short answer is yes—you can drink coffee while intermittent fasting.

The long answer is a little more complicated.

Caffeine and water are the main components of coffee. The amount of water in coffee doesn’t matter when it comes to IF, but caffeine does.

Caffeine is a natural stimulant. It helps wake you up, boosts energy levels and alertness, and improves concentration and focus. Studies show that consuming caffeine can boost metabolism by 3–11%, enhance athletic performance by increasing fat oxidation, reduce fatigue, increase alertness and improve cognitive function.

The downside of caffeine is that it can cause side effects like headaches, jitters, insomnia, restlessness, and nervousness if consumed in high amounts. The average cup of coffee contains 95mg of caffeine. However, other sources of caffeine, such as tea or energy drinks, could have more than this amount per serving.

Suppose you’re sensitive to caffeine or have high blood pressure. In that case, it’s probably best to avoid drinking coffee while fasting to prevent any unwanted side effects from consuming too much caffeine during your fasting window.

What is the fast body on coffee?

The fasted body on coffee is a popular intermittent fasting weight loss strategy. The idea is that by skipping breakfast and drinking coffee on an empty stomach, you can accelerate fat loss.

The fasted body on coffee was popularized by Martin Berkhan, who promotes it as a way to speed up fat loss and increase energy levels for people who are already lean.

Martin’s approach is based on the Leangains protocol, which involves training in the morning and eating within two hours of waking up. He recommends drinking one (or more) cup(s) of black coffee before training, then having breakfast after your workout.

Fasted Body on Coffee is a protocol for boosting your metabolism, improving digestion and reducing inflammation. It’s also a great way to jump-start weight loss if you’ve been struggling with plateauing or slow results.

The protocol involves drinking coffee before breakfast, followed by a fasted workout later in the day. The idea behind it is that caffeine has thermogenic properties that increase your metabolism and improve digestion while fasting helps you burn fat and increase energy levels.

It’s important to note that Fasted Body on Coffee is not just any old fasted workout — there are specific guidelines that make it more effective at burning fat than other fasted workouts.

How does coffee intake affect intermittent fasting?

Coffee doesn’t have a huge impact on intermittent fasting, but it can slightly increase the length of your fast.

When you drink coffee, the caffeine is absorbed into your bloodstream and reaches its highest level after about 30–60 minutes. Fasting slows down the absorption of caffeine, so it takes longer for the effects of caffeine to kick in when you’re fasting.

This means that if you drink coffee right before you break your fast, the effects of the caffeine will last longer and help keep you feeling alert and energized during your eating window.

Can coffee boost the effects of intermittent fasting?

Coffee is often touted as a natural appetite suppressant, but can it actually help you lose weight by boosting the benefits of intermittent fasting? A new study suggests that it might be possible.

Intermittent fasting is a dieting strategy that involves alternating between periods of eating (or “feeding”) and not eating (or “fasting”). For example, an intermittent fast might involve eating dinner one night, then skipping dinner and breakfast the next day before eating lunch as normal.

Coffee can slightly boost the effects of intermittent fasting by increasing the length of your fast and helping to keep you feeling alert and energized during your eating window.

What is The Coffee Effect?

The coffee effect is the hypothesized link between coffee consumption and intermittent fasting. The coffee effect suggests that drinking coffee while intermittent fasting can help you burn more calories and lose weight.

The caffeine in coffee increases your metabolic rate, which helps you burn more fat. Caffeine also reduces fatigue and increases alertness, which can make fasting easier. And it may help prevent muscle loss during fasting by increasing growth hormone levels.

Does coffee break your fast?

Does coffee break your fast?

Intermittent fasting is a trend that has become quite popular in recent years. It’s essentially eating in a restrictive window of time, usually between the hours of 11am and 7pm or 12pm and 8pm. You fast during this window and then eat whatever you want outside of it.

Many people do intermittent fasting to lose weight, but it can also help with other health issues like diabetes, heart disease, and cancer prevention. There are many different types of intermittent fasting, including 16/8 (16 hours of fasting and 8 hours of eating), 5/2 (5 days of fasting and 2 days of eating), and alternate day fasting (ADF).

Intermittent fasters get most of their calories from fat on non-fasting days and eat high-protein meals on fasting days. Because they usually reduce calories overall, they see good results in weight loss without eating less food or exercising more than usual.

Some people drink coffee while intermittent fasting because they feel it helps them focus better throughout the day without caffeine crashes between meals. Others don’t drink coffee but use bulletproof coffee as a meal replacement during their fasts.

Black coffee

If you want to drink coffee while intermittent fasting, the best option is black coffee because it’s a zero-calorie beverage that can help boost your metabolism. While drinking iced or hot tea is fine (I am not encouraging you to avoid those), diet soda and other flavored beverages may cause blood sugar spikes when consumed with a meal or snack.

Black coffee has no calories, so it won’t mess up with any results from your intermittent fast and will also help trigger your body’s fat-burning hormones. In addition to promoting weight loss, black coffee also improves athletes’ brain function and endurance levels—so go ahead! Drink up!

Bulletproof coffee

Bulletproof coffee is a popular version of the ketogenic diet that many people have tried. It involves adding butter and coconut oil to your cup of coffee. Bulletproof coffee was invented by Dave Asprey, who created the Bulletproof Coffee Company in 2010.

The original recipe calls for one to two tablespoons of butter and one teaspoon of coconut oil per cup, which is then added to hot coffee. The mixture should be blended until there are no clumps left—but you don’t want it too frothy either!

As far as benefits go, bulletproof coffee may help you lose weight if you’re following a strict calorie-controlled diet or intermittent fasting plan along with it; otherwise, it’s not likely to impact your weight loss goals much at all (although some people claim they’ve lost weight without changing anything else).


Caffeine is a stimulant that acts as a natural energizer for your body and mind. It increases alertness and concentration, which can help you stay focused on the task at hand.

And because it makes you feel more productive, caffeine can help you lose weight by encouraging you to be more active throughout the day.

Caffeine also improves athletic performance by increasing the amount of fatty acids in your bloodstream, so your body has more energy for exercise or play.

It’s not just for athletes, though! Caffeine also helps improve mental performance—especially regarding memory-related tasks like remembering long lists or performing math problems in your head (if any of these sound familiar). And last but not least, caffeine helps improve physical performance by increasing blood flow through your circulatory system so that oxygen gets into muscles faster during physical activity—which means less fatigue overall!

Additional beverage consumption

The next thing to know is that most beverages you can drink while intermittent fasting are non-caffeinated. For example, water, tea, and other non-caffeinated beverages are all fine to drink during the fasted state. This includes coffee substitutes like dandelion root tea, or lemon/ginger juice with stevia (but avoid fruit juices).

However, avoiding sodas, other sugary drinks, and dairy products like milk and protein shake is important. The same goes for vitamin waters or energy drinks. Sports drinks are also not permitted because they contain both sugar and electrolytes (which will keep your body from going into ketosis). If you’re looking for something similar to Gatorade or Powerade without all these ingredients—we highly recommend Hammer Nutrition Perpetuem Endurance Formula powder mixed with water or coconut water!

Cream in your coffee.

Coffee cream is a great way to increase the calorie density of your coffee. The cream can be a valuable addition to your diet if you want to gain or maintain weight. It’s also a good source of protein and fat, which can help keep you feeling full for longer.

However, if you’re looking to lose weight and body fat, the cream isn’t ideal because it packs on an extra 100 calories per tablespoon (about 16% of what an average adult needs in their daily diet).

Use unsweetened almond milk in your coffee.

If you’re worried about calories and sugar, almond milk is a good choice. It’s not a high-fat dairy product, so there are no calories or grams of fat per serving. Almond milk is also low in sugar and has just 60 calories per cup. Consider unsweetened coconut milk if you’re looking for another option that’s even lower in calories and sugar.

There are many reasons why people choose to drink almond milk over cow’s milk: it’s low in calories and high in protein; it doesn’t contain lactose; it has added calcium (which helps build strong bones); and it contains no cholesterol or saturated fat—all of which benefits those with specific dietary restrictions (for example, vegans).

Use sugar-free sweeteners in your coffee.

Sugar-free sweeteners are okay, but it’s important to note that you should only use a small amount. Sugar-free sweeteners like stevia and artificial sweeteners like Splenda will add extra calories to your coffee, which will not contribute to weight loss.

If you’re not fasting, then sugar-free sweeteners are fine for adding flavor to your coffee. Just be mindful of how much you add! If you decide to add sweetener during a fast day, try using just half a packet instead of one full packet (or even less).

If you’re fasting or on a keto diet, it’s best not to use any sweetener in your coffee because they can cause cravings and spike insulin levels, which could impact your results from intermittent fasting.

Stick to black coffee during fasting periods

For the best results, stick to black coffee during fasting periods and unsweetened almond milk or cream during non-fasting periods.

While the benefits of intermittent fasting are well-documented, there are certain drinks and foods you should avoid during fasting periods—such as coffee. The caffeine in coffee can make it harder to sleep at night, but it also causes blood sugar levels to spike. When you drink coffee on an empty stomach, your body releases insulin, which can cause an energy crash later in the day as your body works overtime trying to process all that sugar and caffeine.

Intermittent fasting is not about going cold turkey; you should still be able to enjoy a cup of coffee once in a while! There’s nothing wrong with drinking “bulletproof coffee” (black coffee blended with grass-fed butter) or unsweetened almond milk instead of regular milk while fasting. If you want a little more flavor than just black coffee (which gets boring after awhile), try one tablespoon of unsweetened cream and a sugar-free sweetener like stevia or monk fruit extract added before blending—you won’t even taste them!

Fasted Body on Coffee and Intermittent Fasting

Can Coffee Boost the Effects of Intermittent Fasting?

  • Caffeine can boost your metabolism.
  • Caffeine can increase your alertness.
  • Caffeine can improve your mood.
  • Caffeine can help you focus on whatever task is at hand, whether it’s writing a book or watching Netflix.
  • In some cases, caffeine may protect against heart disease and dementia (the jury is still out on this one).

1. Coffee suppresses appetite and increases metabolism.

The caffeine in coffee promotes lipolysis, a process by which fat is broken down into glycerol and fatty acids to be used as energy by your body. The weight loss from this increased metabolism varies depending on the person, but it could be between 2 and 12 pounds per month (even if you don’t change anything else).

2. Caffeine improves performance and increases endurance.

When you’re well-rested, caffeine can help you train longer and harder. But when your body is fatigued, caffeine can improve performance by helping to increase adrenaline levels.

When your muscles are tired and your brain feels foggy, caffeine can help you train more efficiently—meaning that the same amount of effort will yield better results.

Caffeine also helps people recover faster after intense workouts by reducing muscle soreness and allowing the body to use oxygen more efficiently during exercise.

3. Coffee can improve mood and focus for better workouts.

Caffeine can enhance mood, reduce fatigue, and improve athletic performance. Athletes who take caffeine have been shown to have increased reaction time and endurance and improved strength and power. Caffeine also increases the production of adrenaline, which is associated with alertness.

While some people are sensitive to caffeine’s effects on their bodies, others may not notice a difference in mood or energy levels when they consume it in small amounts (one or two cups). However, if you notice a significant improvement after consuming coffee before exercising—even at lower doses—you may consider adding it to your routine.

4. Coffee helps to reduce the risk of developing type II diabetes.

Coffee helps to reduce the risk of developing type II diabetes. This is a condition in which the body does not use insulin properly and therefore cannot control blood sugar levels. People with diabetes have high sugar (glucose) and fat levels in their bloodstream. High blood sugar levels mean that too much glucose stays in circulation instead of being absorbed by cells for energy or stored as glycogen for later use.

Coffee reduces the risk of type 2 diabetes by lowering insulin resistance, making it easier for cells to absorb glucose from your bloodstream at a healthy rate. It also lowers blood glucose levels after eating meals. The most active compounds in coffee beans are thought to be cafestol palmitate and kahweol palmitate, which can improve insulin sensitivity during exercise or at rest.

5. Caffeine is a natural diuretic that aids in water loss and recovery from dehydration.

  • This means that if you are dehydrated, caffeine can help you lose weight. It also helps reduce the risk of developing type II diabetes by improving the body’s ability to metabolize glucose.

Drinking coffee can help you train harder, work longer, lose weight, and improve your overall health.

  • Caffeine is a natural diuretic and can increase metabolism by 3–11%.
  • Drinking coffee can help burn fat because caffeine can increase the epinephrine in your bloodstream, which kickstarts your body to burn fat for energy. Additionally, caffeine boosts the production of adrenaline—another hormone that triggers fat loss.
  • Drinking coffee before workouts will also help keep you hydrated by making it easier for fluid to pass through your kidneys into urine rather than reabsorbed back into the bloodstream.

What can I put in my coffee that won’t break my fast?

You can add milk to your coffee. Some people find that adding a splash of half-and-half or heavy cream makes the taste more enjoyable and cuts down on the bitterness. You can also try adding some honey for sweetness if you struggle with this aspect.

Many drinks, such as chai tea lattes, combine spices and sweeteners with black tea or coffee. Adding cinnamon to your cup is another option that may help mask some of the bitterness associated with fasting. Vanilla extract—or other extracts such as almond or coconut—adds flavor without adding calories or sugar. Cocoa powder can do the same thing—it will add texture and body without adding calories! If none of those options sound like something that would taste good in your morning brew (or if you’re looking for something more exotic), the vanilla syrup is one last option worth considering: it’s just sugar water with natural flavors added to give it an extra kick (but technically no caffeine).

Can coffee enhance the effects of intermittent fasting?

Coffee can enhance the benefits of intermittent fasting.

  • Coffee can help you burn more fat.
  • Coffee can help you build more muscle.
  • Drink coffee for faster weight loss and to live longer!


In this article, we hope to shed some light on intermittent fasting and explored how coffee can help you get the most out of it. As you’ll remember from earlier in the post, intermittent fasting should be done with caution—especially if you have certain medical conditions that make it dangerous. Luckily, as long as you check in with your doctor first, coffee can enhance many benefits associated with intermittent fasting: increased mental clarity and focus, better memory capacity, improved heart health, and lower cancer risk. Plus, getting your daily cup or two will help keep hunger pangs at bay! Of course, other things may break your fast, too (like adding cream), so always do your research beforehand before trying anything new out.

We have to say that, as far as workout supplements go, coffee is one of the best. It tastes great and is easier on your pocketbook than much of the other stuff. And if you don’t feel like brewing up a cup of Joe every morning, some good-tasting instant coffee powders can be found in many grocery stores. So the next time you see the barista at Starbucks or your local coffee shop, tell them about their awesome brew benefits for fitness enthusiasts!

To sum it all up, in general, you can safely drink coffee while intermittent fasting. The key is to keep it simple and not add sweeteners or dairy products like milk that may break your fast. If you enjoy having a little cream in your coffee, I recommend doing this during your eating window rather than while intermittent fasting.
