Key Takeaways
  • You can easily start intermittent fasting just by skipping breakfast, and you'll find that a fasting window of around 16 hours is highly effective.
  • Sipping on butter coffee or adding MCT oil can help curb your morning hunger and support your transition into ketosis, but remember to enjoy them in moderation.
  • While you can look forward to physiological benefits like ketosis and autophagy, it’s important to remember that this approach isn’t for everyone, so please listen to your body and stay mindful of any changes.
  • Start gently and gradually extend your fasting window. If you have sleep issues, chronic conditions, or are pregnant, please consult your doctor.

Introduction: Why is "Intermittent Fasting" Gaining Attention Now?

Intermittent fasting, especially "intermittent fasting," is a lifestyle method that is attracting attention mainly in Europe and the United States. When we actually tried it, we realized that many people felt that they could maintain their concentration in the morning just by having a light breakfast, and that their weight and physical condition improved. Historically, it is an act rooted in human life, including religious fasting, but the modern purpose is not just weight management, but also to improve health at the brain and cellular level. A review by researchers Valter Longo et al. (Cell Metabolism, 2014) also reported that fasting may have a positive effect on cell repair and metabolism.

The Key Benefits We Can Expect from Intermittent Fasting

Ketosis and Fat Metabolism

When carbohydrates are depleted, the body breaks down fat to produce ketone bodies, which are then used as an energy source. You can enter mild ketosis in about 12 hours, and it becomes more stable with 14 to 18 hours of fasting. In our experience, 16 hours of fasting (the so-called 16:8) was easy to integrate into daily life and makes it easier to feel the benefits. Research in sports nutrition also suggests that intermittent fasting can positively influence body composition and mood (J Int Soc Sports Nutr, 2014).

Autophagy and Its Positive Impact on Brain Health

Research suggests that fasting has a positive impact on Brain-Derived Neurotrophic Factor (BDNF) and mitochondrial function, which can lead to improvements in cognitive function and mood. We’ve also seen reports—such as the work by Longo et al.—showing that fasting activates autophagy, our cells' natural "cleanup" process, contributing to anti-aging and disease prevention. To be honest, how quickly you feel the effects varies a lot from person to person, but we find that many people truly notice a positive shift in their overall well-being when they stick with it.

A Practical Guide: How to Keep Going Without Overdoing It and Our Favorite Morning Hacks

Our Recommended Schedule (by Phase)

- For beginners: We recommend starting with a 12-hour fast, as it puts very little strain on the body. Simply finish dinner by 8:00 PM and have breakfast at 8:00 AM the next morning. - Once you’ve gotten used to it: Aim for a 14 to 16-hour window (the "16:8" method is a classic example). An easy way to do this is to finish dinner by 8:00 PM and wait until noon the next day to have lunch. - For an occasional challenge: Some people choose to do a 24-hour fast once a week, but our team reminds you that keeping a close eye on your physical condition is essential for this approach.

Tips for Powering Through Morning Hunger: Butter Coffee and MCT

On those mornings when hunger feels a bit tough to handle, we find that a cup of coffee boosted with MCT oil and butter (preferably grass-fed) can be a real lifesaver. MCTs, or medium-chain triglycerides, help your body transition into ketosis more smoothly and are excellent at keeping you feeling satisfied and full. Our go-to recipe is simple: just take 200ml of black coffee and blend it with 1 teaspoon to 1 tablespoon each of MCT oil and unsalted butter. One small tip from our team: MCT oil can sometimes cause an upset stomach if you have too much too soon, so it’s best to start with a small amount and see how your body reacts. If you aren’t a coffee drinker, feel free to swap it for tea or even take the oil on its own.

Sweeteners and How to Structure Your Meals

If you’ve been adding sugar to your coffee, you might consider switching to alternative sweeteners like stevia, xylitol, or erythritol. However, research suggests that non-nutritive sweeteners could potentially affect your gut environment and appetite (J Clin Endocrinol Metab, 2012), so we believe it’s best to cut back on sweetness whenever possible. For your lunch and dinner, focusing on protein paired with vegetables and moderate healthy fats—while being mindful of excessive carbohydrates—will help you fully reap the benefits of intermittent fasting.

Important Precautions and Who Should Avoid This

Intermittent fasting isn’t a magic bullet that works for everyone. Staying in a constant state of ketosis can sometimes lead to issues like sleep disturbances, irregular menstrual cycles, or becoming underweight, depending on your unique body type. We ask that the following people take extra precautions: - Those who are pregnant or breastfeeding - Children and adolescents in their growth phase - Individuals taking medication for diabetes (due to the risk of hypoglycemia) - Those with a history of eating disorders If any of these apply to you, please make sure to consult with a physician before proceeding. Additionally, on your fasting days, it is crucial to avoid high-intensity workouts, stay on top of your hydration and electrolytes, and resist the urge to binge eat once the fast is over. Our team learned the hard way by pushing ourselves too far at the beginning, so we strongly recommend easing into the process gradually to let your body adjust.

Final Thoughts

Intermittent fasting can be as simple as skipping breakfast, offering potential benefits for both your body and brain through processes like ketosis and autophagy. While MCT oil and butter coffee are effective tools for managing morning hunger, it’s important to be mindful of your intake and how your body uniquely responds. To maximize the benefits, we suggest choosing a sustainable approach that fits your personal lifestyle and consulting a professional if you notice any unusual changes in your health. Here at the geefee team, we recommend starting with a 12-hour fast and gradually adjusting as you listen to your body’s signals. To be honest, many people find that the longer they stick with it, the more they notice a reduction in morning sluggishness and a significant boost in their ability to focus.
