Does fasting lower insulin?
Quick answer
Insulin often falls between meals and during fasting, but the health meaning depends on the person.
Step by step
01 Do not adjust diabetes medication yourself.
02 Track timing and symptoms.
03 Ask a clinician if you monitor glucose.
The longer answer
NIA describes fasting as shifting from glucose and glycogen toward fat-derived energy and ketones, and notes that insulin levels may be affected. People with diabetes or medication need medical guidance.
