In today’s busy society, it’s easy to fall into bad habits, such as lack of sleep, excessive sugar intake and fast food. These habits can lead to obesity, low energy and reduced cognitive ability. Fortunately, there is a solution that can help you improve your mental clarity and concentration, while maintaining a healthy lifestyle: Intermittent fasting.

Intermittent fasting is an eating plan that involves alternating between periods of eating and fasting. It’s not a diet, but a lifestyle that can be adapted to your own needs and preferences.

As someone who previously had a poor lifestyle, I can personally attest to the benefits of changing my habits. A few years ago, I decided to make a change and changed my lifestyle, which resulted in a completely different energy and steady improvement in chronic ailments. Now that I’ve discovered the joys of intermittent fasting and a ketogenic diet, I want to share this knowledge with you.

Why intermittent fasting?

Intermittent fasting has a number of benefits, including weight loss, increased longevity and improved brain function. It gives the body time to cleanse itself and use up the nutrients from previous meals, activating a process called “metabolic switching”. This process is known to slow down aging and disease processes, as well as increase neuroplasticity in the brain.

Studies show that intermittent fasting can improve concentration and increase resistance to brain injury and disease.

How to combine intermittent fasting with a ketogenic diet

Combining intermittent fasting with a ketogenic diet can amplify the benefits of both methods. A ketogenic diet involves cutting out refined products such as sugar, grains, starches and refined oils, and instead focusing on healthy fats, proteins and vegetables. Here are some tips for integrating intermittent fasting and a ketogenic diet into your life:

  1. Find a fasting method that suits you: There are several methods of intermittent fasting, such as the 16:8 method (16 hours of fasting and 8 hours of eating) or the 5:2 method (5 days of normal diet and 2 days of reduced calorie intake)[^7^]. Find the method that works best for you and your lifestyle.
  2. Plan your meals: When following a ketogenic diet, it’s important to plan your meals to ensure you’re getting all the necessary nutrients. This can include creating a weekly menu, shopping list and preparing meals in advance.
  3. Stay hydrated: Drinking enough water is essential to support your body’s functions, especially during intermittent fasting. Make sure to drink plenty of water throughout the day, both during fasting and eating periods.
  4. Listen to your body: It’s important to pay attention to how your body responds to intermittent fasting and a ketogenic diet. If you experience side effects such as dizziness, nausea or headache, it may be necessary to adjust your plan.

My personal experience

After changing my lifestyle, I’ve found that intermittent fasting and a ketogenic diet work best for me. I like to fast through the workday, allowing my body to function on ketones, and then enjoy a delicious and filling dinner with my family. This gives me a calm and pleasant feeling of fullness, while also fitting conveniently into everyday life with dinner with the kids and wife.

Eating a ketogenic diet and practicing intermittent fasting has helped improve my mental clarity, concentration and overall wellbeing.


Intermittent fasting and a ketogenic diet can be a powerful combination for improving mental clarity and increased concentration, as well as a host of other health benefits. By finding a plan that works for you and listening to your body’s signals, you can experience the benefits of this lifestyle change.
