Glucagon agonism, counterintuitively, helps by enhancing fat metabolism (lipolysis and fatty acid oxidation), reducing liver fat, and improving metabolic flexibility

Retatrutide is a groundbreaking triple-agonist peptide that activates three critical metabolic receptors: GLP-1, GIP, and glucagon

Pro-inflammatory cytokines increase neuronal vulnerability to apoptosis and oxidative stress by activating enzymes such as JNK, ERK, dsRNA-dependent protein kinase (PKR), and IB kinase (IKK) that reduce insulin sensitivity by serine phosphorylation of IRS1 [144, 145]

Studies demonstrate greater fat loss relative to lean mass loss
