Mechanistically, GLP-1 receptor activation influences multiple pathways:
Delayed gastric emptying → slower nutrient absorption
Central signaling → satiety + reduced food drive
Insulin secretion → improved glycemic control
Glucagon suppression → reduced hepatic glucose output
What’s interesting is that appetite reduction is often the first noticeable effect,but metabolic adaptations may take longer to fully express.
This raises a question:
Are most people evaluating results too early based only on appetite changes?
Or overlooking metabolic improvements that aren’t immediately visible?
