The Metabolic Classroom with Dr. Ben Bikman

A science-first tour of ivermectin’s biological actions beyond antiparasitic use. Discussion covers its Nobel-linked origins, effects on mitochondria and complex I, and why that creates an energy crisis in cancer cells. They explore anti-inflammatory and metabolic signaling through AMPK, NF-kappaB, and FXR, plus preliminary human observations and safety versus politicized narratives.

They explore how short sleep rewires hunger hormones, lowering satiety signals and boosting hunger drivers. The conversation covers why sleep loss heightens cravings for calorie-dense, rewarding foods and the role of the endocannabinoid system. You’ll also hear about orexin, cortisol, melatonin, and why early-night deep sleep is especially protective for metabolic health.

A metabolic take on Alzheimer’s: the talk challenges the amyloid plaque story and explores brain insulin resistance as a central driver. It covers how APOE4 may impair insulin signaling, why glucose use falters while ketone use stays intact, and how diet, ketones, and lifestyle might prevent or support brain health.

They unpack why fat cell size and how fat is stored matter more than total body fat. They compare surprising diabetes rates between countries to illustrate the point. They explain hypertrophy versus hyperplasia in fat, how dysfunctional fat drives liver fat and inflammation, and how genetics and ethnicity set a personal fat threshold for metabolic risk.

They explore how bile acids act like hormones to control liver fat, glucose production, and insulin sensitivity. Discussion covers enterohepatic recycling and two key receptors, FXR and TGR5, that affect energy expenditure, GLP-1 release, and inflammation. They also examine impacts of gallbladder removal and compare bile supplements such as ox bile and TUDCA.

They question LDL as the main cause of heart disease and spotlight why many with heart attacks have normal LDL. The conversation highlights insulin resistance, metabolic syndrome and type 2 diabetes as stronger risk drivers. They promote the triglyceride-to-HDL ratio and other metabolic markers as practical, accessible predictors. The focus shifts from cholesterol numbers to underlying metabolic health.

Conversation about tiny extracellular vesicles that muscles release during movement and how they send molecular messages to the brain, liver, fat, and immune system. Discussion of how different workout types and intensities change the vesicle cargo. Exploration of harmful vesicles in obesity and how exercise can replace them with beneficial signals. Glimpse at future personalized and therapeutic possibilities.

A deep dive into how the NAD⁺/NADH balance acts as a cellular battery and what happens when excess NADH from high glucose derails metabolism. Discussion of mechanisms like mitochondrial dysfunction, ceramide buildup, and reductive stress. Explores main drivers such as refined carbs, alcohol, aging, and inactivity. Covers lifestyle fixes—carb restriction, exercise, time‑restricted eating, better sleep, and less alcohol.

A crash course on the two molecular switches that steer cellular aging: AMPK and mTOR. How modern diets and excess carbs push cells toward growth mode and away from repair. Why certain longevity drugs raise safety and fertility concerns. Practical dietary levers like fasting, carbohydrate restriction, ketosis, and ketone supplements as alternatives to pharmacology.

Nicotine might not be the villain it's often portrayed to be. When isolated from cigarettes, it displays intriguing benefits like anti-inflammatory effects and potential therapeutic roles in ADHD, autism, and cognitive decline. The discussion reveals that nicotine isn't the main addictive factor; additives like pyrazines amplify addiction. Moreover, it activates pathways that may help conditions like ulcerative colitis. However, caution is advised, as prolonged use may lead to insulin resistance. The importance of more research and professional consultation is emphasized.
