In adults with MASLD who do not have type 2 diabetes, stopping liraglutide leads to measurable increases in specific blood proteins and changes in gene activity in fat tissue after 12 weeks, but...
Mechanism
Synthesis from 1 study
When the drug that mimics a natural hormone is stopped, fat tissue loses its normal control and starts sending out stress signals, raising specific proteins in the blood. This doesn't happen when weight loss comes from diet and exercise because those changes don't rely on that hormone system to...
Most probable mechanism
When the drug that mimics a natural hormone stops working, fat tissue loses its normal regulation, starts sending out confusing signals, and releases proteins into the blood that signal stress and inflammation. This doesn't happen when weight loss comes from diet and exercise because those changes don't rely on this hormone pathway.
Abrupt cessation of GLP-1 receptor activation removes tonic signaling that maintains metabolic and transcriptional stability in subcutaneous adipose tissue
Loss of GLP-1 signaling alters gene expression in adipose tissue, including upregulation of calcium/calmodulin-dependent protein kinase II beta, disrupting cellular signaling networks
Dysregulated adipose tissue increases secretion of MMP-10, IL10RB, FGF-23, and Flt3L into circulation, reflecting a state of metabolic stress and immune activation
Reduced glucose uptake by adipose tissue and rebound in hepatic glucose flux restore substrate availability for de novo lipogenesis, contributing to metabolic instability
Less supported by current evidence, but not ruled out
After stopping the drug, the balance of gut bacteria may shift in a way that favors energy storage and low-grade inflammation, though this has not been proven to directly cause the observed protein changes.
Loss of GLP-1 receptor signaling reduces microbial diversity and increases the relative abundance of Firmicutes over Bacteroidetes
Altered microbial composition enhances energy harvest from diet and promotes low-grade endotoxin exposure
Microbial-derived signals may indirectly amplify adipose tissue inflammation and systemic cytokine release
