Fasting has become one of the most popular health and wellness strategies in recent years, particularly in the context of weight loss, metabolic health, and intermittent fasting protocols. With this trend, a new product has surged in popularity—It Works Keto Coffee. Marketed as a convenient, delicious, and fast-acting tool for boosting ketosis, many people wonder whether consuming this product breaks a fast. This article dives deep into the science, ingredients, and fasting principles to answer the burning question: Can you drink It Works Keto Coffee while fasting?
Whether you’re practicing time-restricted eating, extended fasts, or a keto-focused intermittent fasting plan, understanding how keto coffee affects your fast is crucial. Let’s explore the nuances of fasting, what It Works Keto Coffee contains, and whether it supports or hinders your goals.
Understanding Intermittent Fasting and Its Goals
Before analyzing the impact of any beverage—especially one infused with functional ingredients—on a fast, it’s essential to define what fasting actually means and what your goals may be.
What Is Fasting?
Fasting refers to voluntarily abstaining from consuming calories for a set period. While the most traditional form involves consuming no food or caloric beverages, modern fasting practices—especially intermittent fasting—allow for flexibility, such as drinking water, herbal teas, or black coffee.
There are several popular fasting approaches:
- Time-Restricted Eating (TRE): Eating within a 6–10 hour window, fasting the rest of the day.
- 16:8 Method: Fasting for 16 hours and eating within an 8-hour window.
- 24-Hour Fast: Going without food for an entire day.
- Alternate-Day Fasting: Alternating between regular eating and fasting days.
- Keto-Focused Fasting: Combining a ketogenic diet with fasting to enhance fat-burning.
Why Do People Fast?
Fasting serves multiple purposes, and your personal goal influences what can or cannot be consumed during your fast. Common objectives include:
- Weight loss: Triggering fat burning by depleting glycogen stores.
- Insulin sensitivity improvement: Lowering insulin levels through regular fasting periods.
- Autophagy stimulation: A cellular cleanup process activated during prolonged fasts.
- Mental clarity and energy: Many people report improved focus during fasting states.
- Gut rest: Allowing the digestive system to recover and reset.
The criteria for “breaking a fast” vary based on your goal. For example, a single calorie-containing drink might not significantly impact fat loss, but it could interfere with autophagy.
What Is It Works Keto Coffee?
It Works Keto Coffee is a dietary supplement that blends instant coffee with added medium-chain triglycerides (MCTs), BHB ketones, collagen, and other functional ingredients. It’s designed to mimic the benefits of a ketogenic diet—even if you haven’t strictly followed one—by boosting blood ketone levels and promoting fat as fuel.
This isn’t just your average cup of Joe. It Works markets its Keto Coffee as a tool to support energy, mental clarity, and weight management. But does it interfere with your fasting efforts?
Key Ingredients in It Works Keto Coffee
Let’s break down the formula to understand its caloric and metabolic impact.
- MCT Oil (Medium-Chain Triglycerides): Rapidly absorbed fats that convert into ketones in the liver, supporting ketosis. MCTs typically contain about 8 kcal per gram.
- BHB (Beta-Hydroxybutyrate) Salts: Exogenous ketones that immediately raise blood ketone levels. These are salts like sodium, calcium, or magnesium bound to BHB for absorption.
- Coffee (Instant): Provides caffeine for energy and alertness, but the amount varies by serving.
- Collagen Peptides: A protein derived from animal sources; it contains calories and amino acids that may trigger insulin release.
- Flavorings and Natural Additives: Might include stevia, natural flavors, and emulsifiers.
A typical serving of It Works Keto Coffee (one sachet) contains roughly:
| Nutrient | Amount per Serving |
|---|---|
| Calories | ~60-80 kcal |
| Total Fat | ~6–7g (mostly MCTs) |
| Protein | ~3–4g (from collagen) |
| Carbohydrates | ~0–1g |
| Caffeine | ~80–100mg |
These numbers can vary slightly depending on flavor and specific product version, but the above range is representative.
Why It Works Keto Coffee Promotes Ketosis
The inclusion of MCTs and BHB ketones is what allows this coffee to promote ketosis:
- MCTs are converted into ketones faster than other fats, providing instant fuel for the brain and muscles.
- BHB salts elevate circulating ketone levels, which can enhance mental performance and reduce hunger during fasting.
However, it’s critical to note that elevated ketones do not necessarily mean you’re in a fasted state. You can be in ketosis—burning fat for fuel—without being in a true fast.
Does It Works Keto Coffee Break a Fast?
This is the crux of the matter. The answer depends on how you define “fasting” and what your goals are. Let’s examine through several lenses.
Fasting for Weight Loss and Fat Burning
Many people fast to create a caloric deficit and increase fat oxidation. In this context, consuming small amounts of calories may not significantly hinder weight loss—as long as total daily intake remains low.
That said:
- 60–80 calories per serving is not negligible in a strict fast, but it’s minor compared to a meal.
- MCT oil is almost entirely fat, which is metabolized differently than carbohydrates. It may actually support fat-burning by increasing ketone production.
- Caffeine has been shown in studies to suppress appetite and slightly increase metabolic rate.
For individuals fasting with the goal of fat loss or appetite suppression, It Works Keto Coffee may still be beneficial and only marginally disrupt the fast.
Fasting for Insulin Control
One of the main benefits of fasting is lowering insulin levels. When insulin is low, your body releases stored fat for energy.
Here’s the issue: collagen peptides are a source of protein. Protein intake—even without carbs—can trigger an insulin response. While not as potent as carbohydrates, even small protein loads may stimulate insulin secretion.
So while MCTs and BHBs have mild to no insulinogenic effect, the ~4 grams of collagen in each serving could technically spike insulin, which many experts consider a “fast-breaker” in the context of metabolic or insulin-focused fasting.
Fasting for Autophagy
Autophagy is a cellular cleanup process activated during prolonged fasting (generally 12–16+ hours). It’s linked to longevity, reduced inflammation, and cellular repair.
Autophagy is sensitive to both nutrients and mTOR (a cellular growth pathway). Key triggers that suppress autophagy include:
- Protein intake (especially leucine-rich proteins)
- Insulin spikes
- Calorie consumption above minimum thresholds
Given that It Works Keto Coffee contains protein and calories, it’s likely to suppress autophagy to some extent. If your primary goal is cellular rejuvenation or longevity-focused fasting, this coffee may interfere with that process.
Fasting for Gut Rest
Some individuals fast to give their digestive system a break. Consuming fats, protein, and other compounds—even if low-calorie—can stimulate digestive processes such as bile release and gut motility.
Drinking It Works Keto Coffee would trigger the digestive system to process fats and proteins, meaning it does not provide complete gut rest. For those on a healing fast or seeking digestive reset, avoiding all consumables beyond water or plain tea would be ideal.
So, Can You Drink It Works Keto Coffee While Fasting?
The answer is nuanced and highly dependent on your fasting objective.
Yes, If You’re Fasting For…
- Energy and Appetite Control: The MCTs and caffeine can help suppress hunger and provide mental focus, making fasting easier.
- Ketosis Support: It Works Keto Coffee delivers ketones and substrates to help maintain or enter ketosis faster.
- Weight Management on a Time-Restricted Schedule: In a less strict fasting protocol—like 16:8—consuming 60–80 calories without carbs may still keep you close to a fasted metabolic state.
No, If You’re Fasting For…
- Autophagy or Longevity: The collagen and calories will likely stop or delay autophagy.
- Maximum Insulin Sensitivity: Protein intake may spike insulin, negating one of fasting’s key benefits.
- Complete Caloric Abstinence: By definition, since the coffee has calories, it breaks a strict water fast.
In short: It Works Keto Coffee technically breaks a fast, but depending on your goals, this may not matter as much as you think.
Alternatives: Ketogenic Beverages That Are Fasting-Friendly
If you’re trying to stay as close to a fasted state as possible while still enjoying ketone-boosting benefits, consider these alternatives.
Black Coffee
Plain black coffee has:
- Virtually zero calories
- No protein
- Mild appetite suppression from caffeine
- Potential metabolic boost
It’s universally accepted as fast-safe and supports fat oxidation without interfering with insulin or autophagy.
Water with Lemon or Apple Cider Vinegar (In Small Amounts)
Some people add a splash of lemon juice or a teaspoon of apple cider vinegar to water. The impact is minimal, but watch for even slight caloric or sugar input.
Electrolyte Supplements Without Calories
Add sodium, magnesium, and potassium to water using zero-calorie electrolyte powders. Essential for longer fasts to prevent fatigue or cramps.
Homemade “Bulletproof” Coffee (Modified)
A half-serving of MCT oil (1–2g) in black coffee delivers ketones with minimal calories and no protein. This keeps insulin spikes low and may support ketosis without fully breaking the fast.
When Is It Okay to Drink It Works Keto Coffee During Fasting?
While it breaks a strict fast, It Works Keto Coffee can still be a valuable tool when timed correctly.
Use It to Transition Into Eating
If you’re nearing the end of your fasting window, having Keto Coffee can serve as a pre-meal ritual. The collagen provides amino acids, MCTs support energy, and the BHBs maintain ketosis—preparing your body for your first meal without causing a blood sugar crash.
Use It During Less Strict Fasting Protocols
For those following fat-fueled fasting (like a “fat fast”), consuming small amounts of fat with zero carbs can still maintain ketosis. In such cases, It Works Keto Coffee fits perfectly as a low-carb, high-fat beverage.
Use It for Performance or Focus
Busy professionals or fitness enthusiasts may use It Works Keto Coffee during a fast to improve cognitive performance. If the fasting goal is clarity rather than strict metabolic benefits, the trade-off may be worth it.
Expert Opinions on Keto Coffee and Fasting
Health and nutrition experts are divided on whether products like It Works Keto Coffee are compatible with fasting.
Dr. Jason Fung (intermittent fasting advocate): Believes that only zero-calorie beverages should be consumed during a fast to preserve insulin reduction and autophagy.
Dr. Rhonda Patrick (longevity researcher): Suggests that protein intake—even small amounts—can inhibit autophagy, so collagen additives are likely detrimental during true fasts.
Low-Carb and Keto Coaches: Many argue that metabolic flexibility allows for some leeway. As long as the beverage doesn’t spike blood sugar or insulin drastically, it can support fasting goals.
This spectrum of opinion highlights that context is everything. There’s no one-size-fits-all answer.
Practical Tips for Using It Works Keto Coffee
If you choose to use It Works Keto Coffee during your fast, here are some guidelines to minimize disruption and maximize benefits.
Time It Strategically
Drink it toward the end of your fasting window, not at the beginning. This preserves the fasted state for longer and uses the coffee as a bridge to eating.
Monitor Your Body’s Response
Track hunger levels, energy, focus, and ketone readings (if using a ketone meter). Some people respond better than others to exogenous ketones and MCTs.
Signs It’s Working For You:
- Reduced hunger
- Sustained mental clarity
- Stable energy without jitters
- Maintained or increased ketone levels
Signs It Might Be Breaking Your Fast Too Much:
- Increased appetite after drinking
- Lower ketone levels (possibly due to insulin)
- Digestive discomfort (MCTs can cause issues in sensitive individuals)
Stay Hydrated
Even when consuming MCTs or BHBs, water remains essential. Pair your Keto Coffee with plenty of plain water to support metabolism and hydration.
Choose the Right Fasting Framework
If you want the benefits of both fasting and keto coffee, consider modifying your fasting approach. For example:
- Use a modified fast with up to 100 non-carbohydrate calories.
- Follow a “ketogenic light fast” that allows healthy fats and limited protein.
- Fast for shorter durations (12–14 hours) and use keto coffee to extend energy and satiety.
Misconceptions About “Bulletproof” and Keto Coffee
There’s a common belief that “fat doesn’t break a fast.” This idea comes from the popularity of Bulletproof Coffee, which is black coffee blended with butter and MCT oil.
Is Fat Calorie-Free?
No. Fat contains 9 calories per gram. Even if it doesn’t spike blood sugar, it still provides energy. Your body must process it via digestion, liver metabolism, and hormone signaling.
Does Ketosis Equal Fasting?
Being in ketosis and being in a fasted state are related but distinct. You can be in ketosis while eating (e.g., on a keto diet), and you can be fasted without any detectable ketones (early in the fast).
While It Works Keto Coffee boosts ketones, it doesn’t replicate all the benefits of true fasting.
Final Verdict: Should You Drink It Works Keto Coffee While Fasting?
Here’s the bottom line:
If your goal is strict fasting—to achieve autophagy, deep insulin reduction, or complete gut rest—then It Works Keto Coffee will break your fast due to its caloric content, protein (collagen), and insulinogenic potential.
However, if you’re fasting for weight management, energy, mental clarity, or easier transition into eating, then this keto coffee can be a helpful adjunct. It may not preserve every benefit of a fast, but it supports ketosis and makes fasting more sustainable.
Think of it this way: It Works Keto Coffee is not a fasting beverage—it’s a ketogenic performance drink. Use it wisely depending on your priorities.
Key Takeaways
- It Works Keto Coffee contains ~60–80 calories and protein, which technically breaks a fast.
- It raises ketone levels through MCTs and BHB salts, supporting energy and focus.
- The collagen content may stimulate insulin and inhibit autophagy.
- For strict fasts (gut rest, longevity, insulin control), avoid it.
- For metabolic or lifestyle fasting, it may be an acceptable addition.
Ultimately, fasting is a personal practice. Listen to your body, define your goals clearly, and use tools like It Works Keto Coffee in a way that supports—not sabotages—your health journey.
Can drinking It Works Keto Coffee break my fast?
Whether It Works Keto Coffee breaks your fast depends on your fasting goals. If you’re fasting for metabolic or weight loss benefits, such as maintaining ketosis or practicing intermittent fasting for fat burning, a low-calorie version of Keto Coffee with minimal ingredients might not significantly disrupt your fast. It Works Keto Coffee typically contains MCT oil and other ketogenic-friendly components that are low in carbohydrates and sugars, which means it may have a negligible effect on insulin levels for most individuals.
However, technically speaking, any caloric intake can break a true water fast, where the goal is zero caloric consumption. For those fasting for autophagy or spiritual reasons, even small amounts of calories from Keto Coffee could interfere with the desired physiological state. It’s important to define what type of fast you’re following—fat-based beverages like this are often accepted in “fat fasting” or clean intermittent fasting methods, but strict fasts would exclude them. Always consider your personal health goals and consult your healthcare provider if unsure.
What ingredients in It Works Keto Coffee affect fasting?
It Works Keto Coffee commonly contains medium-chain triglyceride (MCT) oil, green coffee bean extract, and various flavorings. MCT oil is a source of healthy fat that provides calories—typically around 40–60 per serving—making it a potential fasting disruptor. While fats don’t spike insulin as dramatically as carbohydrates, they still contain energy that the body can use, which may shift your metabolism out of a fully fasted state, especially if you’re aiming for complete caloric restriction.
The green coffee extract in the product contains caffeine and chlorogenic acid, which can support fat burning and mental alertness during fasting but don’t contribute significantly to caloric intake. Artificial sweeteners or flavorings, if present, might affect insulin response in sensitive individuals, although evidence is mixed. To stay as close to a fasted state as possible, check the specific nutrition label of your It Works Keto Coffee version—some blends are formulated to be lower in net calories and carbs, making them more fasting-friendly than others.
Does It Works Keto Coffee help with ketosis during fasting?
Yes, It Works Keto Coffee can support and enhance ketosis during fasting due to its inclusion of MCT oil. MCTs are rapidly converted by the liver into ketones, which serve as an alternative fuel source when glucose is limited. Consuming this coffee can provide a quick boost of energy and mental clarity without relying on carbohydrates, making it easier to adhere to a ketogenic lifestyle even during extended fasting windows.
In addition, the caffeine in green coffee bean extract may increase fat mobilization and metabolic rate, further supporting ketone production. While introducing exogenous ketones or MCTs provides some calories, many people use Keto Coffee intentionally to enter or deepen ketosis, especially in targeted or cyclical ketogenic diets. Therefore, even though it slightly interrupts a pure fast, it can serve as a strategic tool to maintain ketosis and reduce hunger during fasting periods.
Is It Works Keto Coffee suitable for intermittent fasting?
It Works Keto Coffee can be suitable for many intermittent fasting protocols, particularly time-restricted eating plans like 16:8 or 18:6. These methods focus more on timing than on total calorie abstinence, and a low-calorie beverage like Keto Coffee can help suppress appetite and sustain energy without significantly disrupting metabolic benefits. Many intermittent fasters include bone broth, black coffee, or fat-infused drinks to ease into fasting periods, and It Works Keto Coffee fits within that framework.
However, its suitability depends on how many calories it contains and your personal goals. If your aim is maximum fat burning and insulin control, a version with less than 50 calories may still align with your fasting window. But if your protocol emphasizes zero caloric intake, then consuming this coffee—even with healthy fats—would break the fast. Tailor your usage to your fasting style, and consider tracking your results to see how your body responds over time.
Will It Works Keto Coffee spike insulin and break ketosis?
It Works Keto Coffee is unlikely to cause a significant insulin spike for most people, especially because it contains healthy fats like MCT oil and minimal to no carbohydrates. Insulin responses are primarily triggered by glucose and elevated blood sugar, which are not common with fat-based products. The fats in Keto Coffee are metabolized differently and do not prompt the same insulin release as carbs or proteins, helping maintain a state of ketosis.
That said, individual insulin sensitivity varies, and some studies suggest that even fat consumption can lead to a modest insulin response, particularly in people with insulin resistance. Additionally, if the product contains hidden sugars, fillers, or artificial sweeteners known to affect insulin (such as maltodextrin or certain sugar alcohols), this could interfere. Always read the ingredient label carefully—pure versions without added sugars are safest for preserving both ketosis and the benefits of fasting.
Can I drink It Works Keto Coffee during a prolonged fast?
Drinking It Works Keto Coffee during a prolonged fast—such as a 24-hour or multi-day fast—is generally not recommended if your goal is autophagy or deep cellular repair. Prolonged fasting relies on minimal caloric intake to trigger biological processes like autophagy, where cells clean out damaged components. Since It Works Keto Coffee contains calories from MCT oil and possibly other additives, it may reduce or halt these processes by signaling energy availability to the body.
However, some individuals follow modified prolonged fasts, such as fat fasting, where small amounts of fat are consumed to make extended fasting more sustainable. In this context, Keto Coffee could be used to reduce hunger and fatigue without fully breaking the fast’s metabolic benefits. If you’re pursuing therapeutic fasting for health optimization, it’s best to stick to water, herbal teas, or electrolyte supplements without calories. Always evaluate your health objectives and consult a healthcare professional before consuming anything during a prolonged fast.
How can I use It Works Keto Coffee without breaking my fast?
To use It Works Keto Coffee without fully breaking your fast, consider limiting the serving size or choosing a version with no added fats or calories. For example, you could consume only half a scoop or mix it with water or black coffee to reduce caloric density. Many people use such strategies to gain the cognitive benefits of MCTs and caffeine while staying close to a fasted state, particularly early in their fasting window when hunger is most challenging.
Another approach is to consume It Works Keto Coffee at the end of your fasting period, just before breaking your fast with a meal. This allows you to enjoy its ketogenic benefits while still obtaining the advantages of calorie restriction during the majority of the fast. If you’re unsure, tracking biomarkers like blood glucose or ketone levels can help determine how your body responds. Ultimately, slight modifications let you personalize your fasting experience to balance convenience, sustainability, and metabolic goals.
