Glucagon is insulin’s metabolic opposite—but it rarely gets the attention it deserves. While insulin drives energy storage, glucagon signals the body to release and burn stored fuel. Contrary to common belief, glucagon doesn’t burn fat by pulling it directly from fat cells in humans. Instead, its primary fat-burning action happens in the liver, where it suppresses fat creation, increases fat oxidation, and supports ketone production when insulin is low. Understanding the balance between insulin and glucagon is key to improving metabolic health and sustainable fat loss.

LPS-driven inflammation may be a hidden cause of insulin resistance and fatty liver. In this Metabolic Classroom lecture, Dr. Ben Bikman explains how gut permeability fuels metabolic disease — and what strengthens the gut barrier.

Men experience a real hormonal decline called andropause—but unlike female menopause, much of it is driven by metabolism, not age. Here’s how testosterone changes, why insulin resistance and body fat accelerate the decline, and what men can do to support healthy hormonal function.

Omega-3s do far more than support heart health. Research shows that the long-chain forms—EPA and DHA—enhance fat burning, improve mitochondrial function, and amplify muscle growth and recovery. Here’s how these powerful fatty acids influence metabolism and body composition.

Ketones are often seen as backup fuel, but the heart tells a different story. In this article and full lecture, Dr. Ben Bikman explains how ketones support the cardiovascular system as high-octane fuel, reduce the heart’s workload, calm inflammation, protect against oxidative stress, and improve vascular function. When we look at the biochemistry and physiology—not the diet debates—ketones emerge as powerful allies for heart health.

Plant and animal proteins behave very differently inside the body. From amino acid profiles and digestibility to antinutrients and heavy metals, their metabolic impact is not interchangeable. Here’s what the science shows.

Men and women display distinct patterns in fat metabolism and ketone production, driven by hormonal, enzymatic, and adipose-tissue differences. Estrogen enhances fat mobilization and hepatic ketogenesis, while testosterone favors glycolytic pathways. Recognizing these sex-based distinctions refines how we interpret metabolic data and design nutrition strategies in research and clinical settings.

A concussion triggers a metabolic storm inside the brain—disrupting glucose use, impairing mitochondria, and creating oxidative stress. But ketones offer a powerful metabolic alternative: they supply energy efficiently, reduce inflammation, and support recovery at the cellular level. This post explores the mechanisms behind concussion-related energy failure and the emerging evidence on how ketogenic metabolism enhances neuroprotection and healing.
