Worth knowing that the injection site changes very little.
The concept of "metabolic set point" and its relevance to maintenance dosing: the body actively defends a weight set point through hormonal feedback (leptin, ghrelin, insulin, GLP-1). After weight loss, these signals shift to promote weight regain[1].
GLP-1 agonists may work in part by resetting this set point — or at least overriding the counter-regulatory signals that drive regain. This would explain why continued treatment maintains weight loss while discontinuation leads to regain.
Understanding maintenance dosing through this lens reframes the drug from "weight loss tool" to "metabolic set point modulator."
