Best Tools for Gut Health & Weight Loss | Dr. Chris Thompson

About this video

Huberman talks with Dr. Chris Thompson, a gastroenterologist and obesity-medicine expert, about gut health, weight loss and metabolic health. Thompson describes the gut as a compartmentalised system involved in digestion and also acting as an endocrine organ, sometimes called a second brain. He argues that fibre feeds gut microbes, and that, in his explanation, unfed microbes can eat the mucus layer and produce less butyrate, weakening tight junctions in a snowball effect. Thompson also argues for looking for metabolic problems earlier than standard markers, describing a sequence that begins with calorie excess and glucose spikes. He suggests a continuous glucose monitor for a month or two to learn which foods spike an individual’s glucose, and discusses fasting insulin as an earlier signal, citing the Whitehall II study as following people over many years. He also notes a study finding that only a minority of lean people met the metabolic-health parameters used.

Key takeaways

• Dr. Thompson argues that fibre feeds gut microbes, which in his explanation helps maintain the mucus layer and tight junctions.
• Thompson describes the gut as both a digestive system and an endocrine organ.
• Thompson recommends learning individual glucose responses, suggesting a continuous glucose monitor for a limited period.
• Thompson presents fasting insulin as an earlier warning signal than the traditional markers he discusses.
• Thompson argues that metabolic dysregulation follows a predictable sequence beginning with calorie excess.
