The gut is much more than a digestive organ. It is a metabolic sensing and signaling system that helps shape how we respond to food, regulate appetite, and control metabolism.
Really enjoyed going deep on this with Andrew Huberman, from gut biology and the microbiome to obesity, GLP-1 therapies, and endoscopic treatments.
Two people can have the same fasting glucose: 92 mg/dL.
One may need very little insulin to keep it there.
The other may need several times as much.
Glucose tells you the result.
Insulin tells you the cost.
That is how metabolic disease can remain hidden for years.
