I am a 25+ year type 1 diabetic who shares this disease with my mother and brother. I can tell you with certainty whenever you have an increase in insulin sensitivity it has to do with an increase in serotonin in your blood. Anything that increases serotonin; alcohol, certain drugs, exercise, etc will increase insulin sensitivity. Serotonin not only modulates but also increases insulin effectiveness.

Whoa. This is a fascinating connection I've never heard of before! Thank you for sharing. Where can I learn more about this?

This would check out with the positive impact that anabolic steroids have on insulin sensitivity too, given literature showing that many of them are serotonergic (IE, nandrolone).

Never thought about this, that's an interesting idea.
