No Willpower to Start Intermittent Fasting?

author avatar Dr. Eric Berg 02/18/2025

You're probably wondering if you have what it takes to succeed with intermittent fasting. You might feel intimidated by the idea of going without food for extended periods.

The secret weapon isn't a magic trick but a very real and practical thing everyone has: intermittent fasting willpower.

Think of willpower as the driver behind your actions and choices, guiding you towards what you want. It's the inner strength that lets you resist temptations and cravings.

When we apply intermittent fasting willpower, we are one step closer to improving our health.

Developing Intermittent Fasting Willpower

Intermittent fasting is more than a diet; it's a test of your resolve, much like training a muscle. This muscle strengthens you in many ways but requires proper nurturing.

Willpower gets stronger with use. The more you practice intermittent fasting, the easier it becomes because you're removing the initial barriers.

The First Step is Always the Hardest

Starting intermittent fasting can be tough, but it gets easier. Many individuals starting IF will want to quit right away due to not being used to it.

Hunger and cravings lessen over time as your body gets used to a new way of eating. Fasting trains your body to get rid of bad habits. The whole purpose of intermittent fasting is to get your body fat-adapted.

Real-Life Training Parallels

Think of basic training in the military, wrestling, or learning to play an instrument. All those situations start off very rough.

Each of these activities builds discipline and willpower through repeated exercises. Intermittent fasting is similar, and over time, this improves many functions of the body.

Practical Steps to Enhance Willpower Through Intermittent Fasting

If you're new to this, start slow. You could see so much potential benefit if you ease your way in.

1. Start with Just Fasting

Don't change your diet drastically at first. Just focus on introducing fasting periods by skipping breakfast and aiming for two meals a day without snacking.

Using MCT oil, such as in Bulletproof Coffee, can help. A Bulletproof Coffee can help you through those first hours and support your efforts.

Find resources online on how to prepare it, making your mornings more manageable.

2. Introduce Keto Gradually

Once comfortable with fasting, start incorporating the ketogenic diet by reducing your carb intake. This helps stabilize your blood sugar, making it easier to get into ketosis.

Lower carbs reduce fluctuations in your blood sugar. Less cravings happen with low fluctuations which can happen with blood sugar control.

3. Find Healthy Alternatives

Identify the foods you crave the most, especially desserts and junk food. Find a better alternative.

Plenty of recipes exist for keto-friendly versions of your favorite treats. Over time, your body won't have the high-carb and high-fat fluctuations of foods from its new changes.

Building Long-Term Habits

Developing intermittent fasting willpower also means building a support system, one that aligns with your goals. Consider your environment.

Think about creating small habits for food, exercise, and sleep. Building a structured day creates support around eating habits.

Creating Structure for Success

Think of all the things that can make it better or worse. Consider support systems outside of the food itself.

Consistent, positive sleep improves insulin and hunger hormones that can affect food decisions the following day. Consider using these key details:

  • Go to sleep by 10:00 pm latest.

  • Attempt to get 8 hours of sleep.

  • Maintain a similar sleep schedule on weekends.

Stay Hydrated

Often, thirst masks hunger. Proper hydration helps support liver function that plays a role in hormone production. All aspects should be working to help you stay on point.

A great plan to keep well hydrated is:

Time

What to Do

Upon waking.

Drink a glass of water before anything else.

Throughout the day.

Drink water every few hours, especially before mealtimes.


How Can Tracking Improve Intermittent Fasting

Keep an honest record of what you eat each day. Take progress of how much weight, how your sleep is improving, how your cravings are changing over time, and much more. Tracking can lead to weight loss.

Here is an example you can use to track some of this valuable data for tracking progress with intermittent fasting:

Tracking Metric

Weekly Note

Morning Weight

Note the weight

Fasting Hunger (0-10)

Record each day

Sleep quality(0-10)

Record the night before.


By staying engaged on a weekly or daily basis in tracking, it really is about personal growth with IF. Keeping your food intake in check during your eating window will only amplify the fasting benefits.

Enhancing Fasting Success with Strategic Fat Intake

Maintaining willpower during intermittent fasting often comes down to how well you manage hunger and energy levels throughout the day.

While fasting relies on avoiding calorie intake for extended periods, incorporating healthy fats during eating windows can improve satiety and support metabolic flexibility.

For example, consuming MCT oil before bed may help curb late-night cravings and provide a steady energy source for the following morning.

MCT oil, derived from coconut oil, is rapidly converted into ketones, which the brain and body use for fuel without raising blood sugar.

This approach can be particularly helpful for individuals who experience sleep disturbances or hunger pangs during fasting periods.

When paired with a well-structured keto diet and proper hydration, adding MCT oil at night can support both willpower and long-term fasting success by stabilizing energy levels and reducing the temptation to break a fast prematurely.

Conclusion

Intermittent fasting is about improving many areas in your life, physically and mentally. You will have higher energy levels and a cleaner bloodstream. When incorporating it into your lifestyle, use the helpful advice mentioned.

Be sure to stay properly hydrated by frequently consuming water and even black coffee, especially if you have a busy day. You need to always be focused on healthy eating.

This isn't a fad or quick-term plan. When you begin to exercise self-control and build up intermittent fasting willpower, your future can change, opening doors that most are not able to walk through.

With improved willpower, you will find you have a better time managing your weight, and you can better maintain long-term health goals.

FAQs about intermittent fasting willpower

Does fasting increase willpower?

Yes, intermittent fasting acts as a training exercise for your willpower, similar to physical workouts. As you stick to fasting schedules, you naturally increase willpower.

Many have been able to break long-term bad habits because they start the process.

Your mental strength is improved. Intermittent fasting involves increasing your mental health.

What is the 80/20 rule for intermittent fasting?

There’s limited evidence to fully prove the 80/20 "rule" for intermittent fasting.

This isn't considered a typical method to use with fasting. Generally, the main aspect is just extending the fasting time periods.

Why is 16 hours the magic number for fasting?

Some research suggests that after around 16 hours of fasting, the body starts using more energy. It also helps to fuel and maintain metabolism.

But a 2020 study in the Journal of the American Heart Association could not fully support this. The results will vary depending on each person's own metabolic health.

Why does intermittent fasting make me feel so good?

Intermittent fasting can boost brain-derived neurotrophic factor (BDNF), a protein that supports brain health and mood. It can influence the regulation of hormones like ghrelin and leptin.

You will generally start to have more sustained energy as you begin the journey with IF. By sticking to an eating pattern within a specific eight-hour window and improving insulin sensitivity, the positive effects are numerous.

Alternate-day fasting and restricting calories could potentially assist with reducing your blood pressure, too.
