Summary of Top Brain Health Tips
4 Key Concepts
Intermittent Fasting
This involves going without eating glucose for about 16 hours a couple of times a week. When glucose reserves are depleted, the liver burns fat into ketones, which the brain can use as an alternative fuel source, similar to a hybrid vehicle, improving attention and focus.
MIND Diet
Essentially a Mediterranean-style diet, the MIND diet has been shown in long-term studies involving thousands of people to reduce the incidence of dementia. It emphasizes plant-based foods, nuts, and occasional fatty fish, while limiting red meat, fried, and processed foods.
Neurotrophic Factors (BDNF)
These are molecules, such as Brain-Derived Neurotrophic Factor (BDNF), that the brain releases, particularly during exercise. They act like 'miracle growth' for the brain, helping to keep blood flow open to its tissues and promoting overall brain health.
Hypnagogic and Hypnopompic States
These are the transitional phases between being awake and falling asleep (hypnagogic) and between sleep and waking up (hypnopompic). During these times, the brain exhibits a unique combination of alpha waves (awake, focused, calm) and delta waves (light sleeping, early dreaming), creating a 'strange portal' to the subconscious that can be leveraged for creativity.
7 Questions Answered
Yes, even at 60 or 70 years old, simple lifestyle changes have been shown to increase performance on cognitive tests, offering an empowering message that it's never too late to optimize brain health.
Intermittent fasting, by going 16 hours without eating glucose a couple of times a week, prompts the liver to burn fat into ketones, which the brain can use as an alternative fuel source, leading to improved attention and focus.
The MIND diet, which is essentially a Mediterranean diet, has been shown to reduce dementia risk. It emphasizes plants, nuts, occasional fatty fish (for omega-3s), and poultry, while limiting beef, fried, and processed foods.
Exercise is beneficial for the brain because it keeps blood flow open to the brain's tissues, preventing damage, and it also stimulates the brain to release neurotrophic factors like BDNF, which act as 'miracle growth' for brain health.
While simply increasing movement is a good start, incorporating some strength training alongside cardio is suggested. The key is to do a little bit more exercise than you are currently doing to encourage the brain to shower itself with BDNF.
Learning new things, particularly music, languages, or engaging in social interactions, forces the brain to pull from different pathways and engage its various corners and recesses. This energy-consuming activity helps to break mental ruts and can stave off dementia.
During the hypnagogic (awake to sleep) and hypnopompic (sleep to awake) states, the brain exhibits unique alpha and delta waves, creating a portal to the subconscious. Focusing on riddles or problems during these 10-20 minute transitions can unlock creative solutions, and it's helpful to keep a pen nearby to jot down ideas.
10 Actionable Insights
1. Prioritize Getting Vertical
Make getting vertical and increasing daily movement a priority, as it’s considered essential for overall well-being. Start by standing more, getting out of your chair, walking, and taking the stairs.
2. Pursue Happiness & Joy
Actively seek out and pursue relationships and crafts that genuinely make you happy, as this is highlighted as potentially the best thing you can do for your brain health.
3. Embrace Mediterranean-Style Eating
Shift your diet towards more plants, nuts, and occasional fatty fish and poultry, following a Mediterranean-style approach. Avoid beef, fried, and processed foods, treating them as rare indulgences rather than regular habits.
4. Continuously Learn New Things
Actively seek out new and unfamiliar content, develop new habits, or learn new skills like music or languages to challenge your brain, break mental ruts, and help stave off dementia.
5. Exercise Regularly for Brain
Engage in regular physical exercise a couple of times a week, as it improves blood flow to the brain and releases neurotrophic factors, which act as ‘miracle growth’ for brain health.
6. Try Intermittent Fasting
Consider skipping breakfast a couple of times a week to practice intermittent fasting, aiming for 16 hours without eating, as this can be good for attention and focus by encouraging the brain to use ketones.
7. Practice Deep Breathing
Take short breaks throughout the day, breathing deeply for five minutes a couple of times, or three minutes three times a day, as this meditative pause can be helpful.
8. Add Strength Training
Incorporate strength training, even with light weights, into your exercise routine, as it is increasingly suggested to be an essential component for brain health.
9. Harness Hypnagogic States
Dedicate 10-20 minutes during the transition from wakefulness to sleep (hypnagogic state) to reflect on riddles or problems, as this period can serve as a ‘strange portal to your subconscious’ for creativity.
10. Capture Morning/Night Thoughts
Keep a pen and paper by your bed to immediately jot down any creative thoughts or solutions that come to mind just before falling asleep or upon waking.

2 Protocols
Daily Brain Health Routine
Dr. Rahul Jandial- Consider skipping breakfast a couple of times a week to achieve 16 hours of intermittent fasting without glucose.
- Take 5 minutes to breathe deeply before lunch, or practice deep breathing for 3 minutes, three times a day.
- Choose brain-healthy foods, emphasizing plants, nuts, and occasional fatty fish (like the Mediterranean/MIND diet), while limiting beef, fried, and processed foods.
- Engage in exercise a couple of times a week, incorporating some strength training, or simply increasing daily movement.
- Read something completely unfamiliar, develop a new habit, or learn new things like music or languages to challenge your mind.
- At night, during the transition from awake to asleep (hypnagogic state), look at riddles or problems to tap into subconscious creativity, keeping a pen nearby to jot down ideas.
Top Tips for Brain Health
Dr. Rahul Jandial- Get vertical: Stand and move more, as being upright and moving is very important for brain health.
- Make subtle but important changes in your diet: Incorporate more elements of the Mediterranean diet, such as plants, salmon, red wine, yogurt, and fruit.
- Find puzzles, new content, or read a book; do something unusual to challenge and engage your mind.
- Pursue relationships and crafts that make you happy, as finding happiness is a powerful way to support brain health.
