In this mini lecture Dr. Bikman explores how concussions cause more than just structural damage to the brain—they create a serious metabolic energy crisis.

A concussion reduces the brain’s ability to use glucose by impairing glucose transporters and glycolytic enzymes, leaving neurons starved for energy just when demand spikes. This disruption persists even after initial symptoms fade and can worsen inflammation and oxidative stress, further harming brain function.

Fortunately, ketones provide a powerful alternative energy source. Unlike glucose, ketones can bypass the damaged pathways and fuel the brain directly via mitochondria, improving ATP production, reducing oxidative stress, and modulating inflammation.

Both ketogenic diets and exogenous ketones (like goBHB) can dramatically improve brain recovery after a concussion and even provide preventative protection for athletes and others at risk of head injuries.

Animal and limited human studies confirm that after injury, the brain increases its ability to use ketones, especially when they are available immediately. Studies show improvements in mitochondrial function, reduced lesion volume, and even increased neuroplasticity and antioxidant gene expression. Whether through fasting, dietary restriction, or supplementation, making ketones available may be a crucial part of supporting the injured brain.

Exogenous ketones—especially beta-hydroxybutyrate (BHB), the most effective and bioavailable form—can provide an immediate and practical energy source for the brain and body, particularly during times of increased demand. A high-quality option is the NSF-certified goBHB from Clean Form Nutrition, where you can use the code BEN10 for a 10% discount: https://cleanformnutrition.com/products/go-bhb

In this Metabolic Classroom lecture, Dr. Bikman explains the crucial role of plasmalogens—a unique type of fat found in the membranes of cells, especially in metabolically active tissues like the brain, heart, and fat cells.

These special fats help keep cells flexible, support insulin signaling, protect against oxidative stress, and even regulate energy production by stabilizing mitochondria. Dr. Bikman details how plasmalogens act as “sacrificial shields” to defend cells from damage and how they enable cell signaling by keeping membranes fluid.

Ben explores how plasmalogens directly impact fat cell behavior, enabling white fat to transform into more metabolically active beige fat. This shift enhances fat burning and improves insulin sensitivity. In fat cells and mitochondria alike, plasmalogens influence thermogenesis, mitochondrial efficiency, and even gene expression related to fat storage and breakdown. Dr. Bikman also highlights how lower plasmalogen levels are linked with obesity, diabetes, and other metabolic disorders.

The lecture then connects plasmalogens to insulin signaling, showing how they support proper insulin receptor function through membrane fluidity and lipid raft formation. Without enough plasmalogens, insulin signaling is impaired, leading to elevated blood sugar and higher disease risk.

Finally, he provides actionable steps to support plasmalogen levels through diet and supplements, including DHA-rich foods, alkylglycerol from shark liver oil, and even prebiotic fibers like inulin.

In this Metabolic Classroom lecture, Dr. Bikman explores the deep biochemical relationship between stress and ketone production, uncovering how the body interprets stress signals as cues to mobilize fat and create ketones.

He explains how stress hormones—like epinephrine, cortisol, glucagon, and growth hormone—aren’t just emergency signals but actually metabolic adaptation hormones that help the body shift into fat-burning mode. Through the sympathetic nervous system and hormone cascades, the body responds to stress by increasing lipolysis and triggering ketogenesis, even during fasting, exercise, or low-carb eating.

Ben walks through how ketogenesis begins at the level of fat cells and liver mitochondria, and how key molecules like acetyl-CoA and oxaloacetate determine whether the body makes glucose or ketones.

Importantly, he clarifies that while stress can trigger positive metabolic shifts, chronic stress without relief can lead to harmful insulin resistance. The takeaway: understanding the difference between acute and chronic stress is key to using this response to your metabolic advantage.
