Topic:

Ben explains how AMPK and mTOR are critical regulators of aging and metabolism, and how their balance can be influenced by diet and lifestyle. Instead of drugs like rapamycin, strategies like carbohydrate restriction and ketosis offer a safer path to optimizing longevity.

Summary:

In this Metabolic Classroom mini lecture, Dr. Bikman explores two of the most important molecular “switches” that regulate how cells age, grow, and repair themselves: AMPK and mTOR.

These pathways operate in a delicate balance—AMPK promotes energy conservation, fat oxidation, and cellular cleanup (autophagy), while mTOR supports cellular growth and protein synthesis. When AMPK is up, mTOR is down, and vice versa.

Ben explains how modern lifestyles—especially chronic overnutrition and excess carbohydrate intake—shift this balance toward persistent mTOR activation, which may accelerate aging and metabolic disease. He critiques the growing popularity of rapamycin for longevity, citing its lack of human data and serious side effects, particularly reproductive harm. Instead, he proposes that simple lifestyle strategies—like carbohydrate restriction, ketosis, and supplementation with ketones like BHB—can more safely optimize the AMPK/mTOR balance.

He also highlights the importance of ketones as both energy sources and signaling molecules that can activate AMPK and stimulate autophagy. The lecture ends with a clear takeaway: longevity and metabolic health may not require pharmaceuticals, but rather informed choices around diet and lifestyle.

Nicotine may not be the addictive villain it's made out to be. When separated from cigarette smoke, it shows surprising anti-inflammatory and neurological potential.

Summary:

In this Metabolic Classroom mini lecture, Dr. Ben Bikman revisits the molecule nicotine—not as an endorsement to use it, but to explore its distinct effects when separated from harmful compounds in cigarettes.

Contrary to popular belief, nicotine alone is not highly addictive; tobacco additives like pyrazines likely amplify the addiction seen in cigarettes. Dr. Bikman details nicotine’s anti-inflammatory properties, particularly through activation of the alpha-7 nicotinic acetylcholine receptor, which may help conditions like ulcerative colitis, sepsis, and arthritis.

Ben also explores its complex effects on metabolism—such as increased thermogenesis and fat oxidation—while warning of potential insulin resistance with sustained use.

Lastly, he reviews fascinating clinical research suggesting therapeutic potential in conditions like ADHD, autism, Tourette’s syndrome, and even Alzheimer’s, all while emphasizing that nicotine, when separated from cigarette smoke, warrants more open scientific inquiry.

Topic Today:

Ketones, particularly BHB, aren’t just backup fuel—they’re powerful signals that affect inflammation, gene expression, and mitochondrial function. This episode shows how BHB acts like a hormone to enhance metabolic health and cellular resilience.

Summary:

In this episode of the Metabolic Classroom, Dr. Bikman explores the remarkable role of beta-hydroxybutyrate (BHB), the most abundant ketone body, as both a metabolic fuel and a cellular signaling molecule. While traditionally seen as mere backup energy, BHB is now recognized as a potent agent that influences gene expression, reduces inflammation, and protects mitochondrial function.

Ben unpacks the dual nature of BHB, describing how it activates specific receptors like GPR109A and FFAR3, modulates immune responses, and directly inhibits the NLRP3 inflammasome, a key player in chronic inflammation. He also highlights how BHB affects epigenetic regulation through HDAC inhibition, enhancing cellular resilience and antioxidant defenses.

The lecture concludes by tying these pathways together to show how ketones—whether produced endogenously or taken as supplements—convey a coordinated biological signal of adaptation and protection. This shift in understanding elevates ketones from mere “backup fuel” to central players in metabolic health.
