156: The Most Dangerous Fat in Your Body

📢 Ask Dr. Bikman’s Digital Mind (multilingual): https://benbikman.com/ben-bikmans-dig... 📢 Dr. Bikman’s Community & Coaching Site: https://insuliniq.com Topic: Visceral fat is dangerous because it sits deep around the organs and drains directly to the liver, sending fatty acids and inflammatory signals where they can drive fatty liver, insulin resistance, and systemic inflammation. The good news is that visceral fat responds strongly to exercise-related catecholamines, making physical activity one of the best tools for reducing it. Summary: 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.
