Topic:

Sleep loss alters key hunger hormones—reducing leptin and increasing ghrelin—while simultaneously activating reward pathways that increase cravings for calorie-dense foods. Because sleep and appetite hormones influence each other in both directions, improving sleep quality may be one of the most powerful tools for regulating hunger and metabolic health.

Summary:

Sleep is often treated as a simple lifestyle choice, but in reality it is one of the most powerful regulators of appetite and metabolic health. In this lecture, Dr. Ben Bikman explains the intricate hormonal relationship between sleep and hunger, highlighting how even short periods of sleep deprivation can dramatically alter the body’s appetite signals. Key hormones such as leptin and ghrelin shift in opposite directions during sleep restriction—satiety signaling declines while hunger signaling increases—creating a biological drive to eat more food.

Ben also explores how sleep deprivation affects additional systems involved in appetite regulation, including the endocannabinoid system, cortisol rhythms, and the brain’s orexin neurons. These changes don’t just increase hunger—they specifically increase cravings for energy-dense, rewarding foods like chips, sweets, and other highly palatable options. Together, these hormonal changes create what researchers describe as an “obesogenic environment,” where the body becomes biologically primed to overeat.

Importantly, the relationship works both ways. Hormones such as leptin and ghrelin also influence sleep quality, while melatonin plays a coordinating role in regulating the entire circadian system. Dr. Bikman concludes by emphasizing that optimizing sleep—especially protecting early-night deep sleep and minimizing artificial light at night—may be one of the most effective interventions for regulating appetite and improving metabolic health.

Topic:

Alzheimer’s disease has traditionally been explained by the buildup of amyloid plaques in the brain, but growing evidence suggests this theory does not fully account for the disease or lead to effective treatments. A metabolic perspective proposes that Alzheimer’s may instead be driven by brain insulin resistance, which disrupts neuronal energy metabolism—while the brain’s ability to use ketones as an alternative fuel remains intact, offering potential strategies for prevention and support.

Summary:

For decades, Alzheimer’s disease has largely been understood through the lens of the amyloid plaque hypothesis, which proposes that sticky protein deposits in the brain trigger neurodegeneration and cognitive decline. In this Metabolic Classroom lecture, Ben explains why that theory is increasingly being questioned. He reviews the historical origins of the plaque hypothesis and the repeated failure of drugs designed to remove amyloid plaques to meaningfully improve patient outcomes. The controversy surrounding manipulated data in influential Alzheimer’s research further highlights the need for a new framework to better explain the disease.

Ben then presents a compelling alternative: Alzheimer’s disease as a metabolic disorder driven by brain insulin resistance. Drawing from mechanistic studies, epidemiological data, and genetic insights, he explains how impaired insulin signaling in the brain can disrupt neuronal energy metabolism, increase tau tangles, impair amyloid clearance, and ultimately contribute to neurodegeneration. This concept has led some researchers to refer to Alzheimer’s as “Type 3 diabetes.”

The lecture also explores a hopeful implication of this metabolic framework. While glucose metabolism is impaired in Alzheimer’s brains, research shows that the brain’s ability to use ketones remains intact. This suggests that strategies that improve insulin sensitivity or increase ketone availability—such as carbohydrate restriction, fasting, exercise, or exogenous ketones—may offer promising avenues for prevention or metabolic support.
