In this lecture, Dr. Ben Bikman explains why visceral fat is one of the most metabolically dangerous forms of body fat. Unlike subcutaneous fat, which sits under the skin and can be pinched, visceral fat is stored deep inside the abdomen around the organs. Its location matters because visceral fat drains directly into the liver through the portal vein, meaning the fatty acids and inflammatory signals it releases reach the liver first and at high concentration.

Dr. Bikman explains that visceral fat is especially harmful because it tends to grow through hypertrophy, meaning existing fat cells get larger rather than new smaller fat cells being created. As these fat cells enlarge, they become insulin resistant and begin leaking fatty acids even when insulin should be suppressing fat release. Those fatty acids can then accumulate in the liver, pancreas, and muscle, contributing to ectopic fat storage, fatty liver disease, and worsening insulin resistance.

The lecture also highlights how enlarged visceral fat cells can become hypoxic, or oxygen-starved, which pushes them to release inflammatory signals and recruit immune cells. This turns visceral fat into an active source of chronic low-grade inflammation. The hopeful takeaway is that visceral fat is also highly responsive to catecholamines, the hormones released during physical activity. Exercise can therefore help reduce visceral fat specifically, even when overall body weight does not change dramatically.

Topic:

Bone is a metabolically active organ that responds to insulin and glucose while releasing hormones that influence the pancreas, fat cells, appetite, and energy use. High glucose and insulin resistance can make bones brittle despite normal density, while resistance training, stable glucose, and good nutrition support both skeletal and metabolic health.

Summary:

Dr. Bikman explains why bone should be understood as a metabolic organ, not just structural scaffolding. Bone is living tissue that is constantly being broken down and rebuilt by opposing teams of cells, and that remodeling process requires energy, nutrients, and hormonal coordination. Far from being inert, bone responds to metabolic signals such as insulin, glucose, and leptin—and it sends signals back to the rest of the body.

Ben focuses first on insulin’s role in bone health. Insulin acts as a growth signal for bone-building cells, helping maintain bone density and structure. In type 1 diabetes, where insulin is absent, bone density and architecture suffer. In type 2 diabetes, the problem is different: bone density may look normal on a DEXA scan, but chronically high glucose can glycate collagen, making bone stiffer and more brittle. At the same time, insulin resistance weakens the bone-building signal, creating the “diabetic bone paradox,” where bones appear dense but fracture more easily.

The lecture then explores bone-derived hormones, especially osteocalcin and lipocalin-2. Osteocalcin can support insulin secretion under glucose stimulation, increase adiponectin from fat cells, improve insulin sensitivity, reduce inflammation, and promote fat burning. Lipocalin-2 travels from bone to the brain after meals and appears to help suppress appetite while also supporting glucose regulation. The practical takeaway is that metabolic health and bone health are deeply connected: stable glucose, good insulin sensitivity, vitamin K, resistance training, and weight-bearing movement all help protect the skeleton and support whole-body metabolism.

In this Metabolic Classroom episode, Dr. Bikman explains mitochondrial uncoupling, a process where cells burn fuel without converting all of that energy into usable ATP. Normally, mitochondria are “coupled,” meaning fuel burning is efficiently converted into cellular energy. But when mitochondria become uncoupled, some of that fuel is released as heat instead—like revving a car engine while it’s in park.

Ben explains that this process is especially important in fat tissue. White fat is designed for energy storage and tends to be tightly coupled, while brown fat is rich in mitochondria and uncoupling proteins that burn fuel to generate heat. He then connects this physiology to insulin, showing that insulin appears to make fat-cell mitochondria more tightly coupled and efficient, lowering energy expenditure and making storage easier.

The opposite happens when insulin is low and ketones rise. Research from Dr. Bikman’s lab shows that ketones, especially beta-hydroxybutyrate, can increase mitochondrial respiration in fat cells without a matching rise in ATP production—clear evidence of uncoupling. In human fat biopsies, elevated ketones were associated with markedly higher mitochondrial respiration, suggesting that ketosis can make fat tissue more wasteful with energy.

The larger takeaway is that calories still matter, but hormones influence how efficiently those calories are stored or burned. When insulin is high, the body stores energy efficiently. When insulin is low and ketones are elevated, fat-cell mitochondria may become more uncoupled, allowing more energy to be dissipated as heat rather than stored as fat.
