The statement about BDNF (Brain-Derived Neurotrophic Factor) is based on a fascinating biological process called Metabolic Switching.

When you aren't using all your energy to digest a big breakfast, your body produces a special protein called BDNF (Brain-Derived Neurotrophic Factor).
When you skip a meal like breakfast, your body eventually runs out of easy energy (sugar) and starts burning fat instead. This "switch" sends a signal to your brain to create more BDNF.

Part 1 The Science: Why does it happen?

From an evolutionary perspective, this was a survival mechanism. If an ancient human was hungry and couldn't find food, their brain needed to be sharper and smarter to find the next meal. BDNF is the protein that makes that happen.

Here is the step-by-step process of how fasting triggers it:

1. Glycogen Depletion: Your body stores sugar (glycogen) in your liver. It takes about 12 to 14 hours of not eating to use most of this up.
2. Ketone Production: Once the sugar is low, your liver begins turning fat into ketones (specifically one called BHB or beta-hydroxybutyrate).
3. The Brain Signal: These ketones aren't just fuel; they are like "text messages" to your brain cells. When BHB reaches the brain, it triggers a gene that tells the brain to produce more BDNF.
4. Neuroplasticity: BDNF then acts like "Miracle-Gro." it helps neurons (brain cells) grow, branch out, and communicate better.

If you want to read the official science behind this, here are the best medical references from 2024 and 2025:

• The New England Journal of Medicine (NEJM): * Reference: Mattson, M. P., et al. "Effects of Intermittent Fasting on Health, Aging, and Disease."

• Summary: This is the most famous study on the topic. It explains that the "G-to-K" (Glucose to Ketone) switch is exactly what triggers BDNF and improves brain resistance to stress.

• Nature Reviews Neuroscience:

• Reference: "Intermittent metabolic switching, neuroplasticity and brain health."

• Summary: This paper details how ketones like BHB act as signaling molecules that specifically turn on the BDNF gene.

• Johns Hopkins University Research:
• Reference: Mark Mattson, Ph.D. (Lead Researcher).
• Summary: Dr. Mattson’s lab has shown in multiple trials that periodic fasting challenges the brain in a way that makes it more resilient, similar to how exercise challenges a muscle to make it stronger.

• Aviv Clinics (2025 Update):
• Reference: "The Effect of Intermittent Fasting on Brain Health."
• Summary: Recent clinical reviews confirm that the ketones produced during fasting promote "resistance to oxidative and inflammatory stress" in the brain.

Part 2 Why does increasing neuroplasticity make you smarter?

• Think of your brain like a giant city. Neuroplasticity is the city’s ability to build new roads, widen old ones, and tear down paths that no longer lead anywhere. When you increase neuroplasticity, you are essentially making that city much more efficient.

Here is the science of why this makes you "smarter" in three simple steps:

1. Faster Information Travel (The High-Speed Highway)

Your thoughts move through cells called neurons. When you learn something new, your brain builds a connection (a synapse) between these cells.

• High Plasticity: Your brain can quickly add "insulation" (called myelin) to these roads. This makes signals travel up to 100 times faster.
• Result: You process information quicker. You aren't "thinking harder"; your brain is just moving data at higher speeds.

2. Better Problem Solving (The Shortcut Effect)

Being smart isn't just about knowing facts; it’s about connecting them. Neuroplasticity allows your brain to create "cross-talk" between different areas—like linking a math skill to a music skill.

• The "Aha!" Moment: With high neuroplasticity, your brain is flexible enough to find new "shortcuts" between ideas that seem unrelated.
• Result: You become more creative and better at solving puzzles because your brain isn't stuck in one way of thinking.

3. Cleaning Out the "Gunk" (Synaptic Pruning)

Part of being smart is forgetting the stuff that doesn't matter. Neuroplasticity includes a process called pruning.

• The Brain's Gardener: Your brain identifies weak connections that you don't use anymore (like an old phone number) and "prunes" them away.
• Result: This frees up energy and space for important information. It reduces "brain fog" and helps you focus on what really matters.

The "BDNF" Connection

As we discussed earlier, BDNF is the fuel for this entire process. Without enough BDNF, your brain stays "stiff"—it’s hard to learn new things and easy to get stuck in old habits. When you increase BDNF through things like fasting or exercise, you are giving your brain the "construction materials" it needs to keep building those highways.

The Key Finding: This research shows that the ability of synapses to strengthen (called Long-Term Potentiation) is the fundamental cellular mechanism behind learning and memory. If you can't change your synapses, you can't learn.

Nature Reviews Neuroscience:

Reference: Neuroplasticity: Cost and Benefit.

The Key Finding: This paper explains that intelligence is directly correlated with "structural plasticity"—the brain's physical ability to change its shape and connections in response to new environments.

Harvard University (Center on the Developing Child):

Reference: InBrief: The Science of Resilience

The Key Finding: They explain that "plasticity" allows the brain to adapt to stress. A smarter brain is a more resilient brain that can stay calm and solve problems under pressure.

Reference: Soft-Wired: How the New Science of Brain Plasticity Can Change Your Life.

The Key Finding: Dr. Merzenich’s lifelong research proved that our brains are "plastic" from birth until death. He showed that by doing specific exercises, we can physically enlarge the parts of the brain responsible for high-level thinking.
