GSEA analysis on the effect of tirzepatide on fatty acid metabolism showed that tirzepatide treatment exerted no significant effect on the mRNA expression of genes involved in fatty acid synthesis (SREBP2, FASN, ACC1, and SCD-1), fatty acid transport (FATP4 and FATP5), lipolysis (Mgll, Lipe, and ATGL), or inflammation (TNF, IL-1, and IL-6), suggesting that tirzepatide has limited effects on multiple metabolic pathways. Since metabolic dysregulation in MASLD also involves the extra-hepatic tissues, the authors analyzed the effect of tirzepatide on white & brown adipose tissues and skeletal muscle

It works by binding directly to the IGF-1 receptor (IGF-1R) on muscle and other tissue, activating the PI3K/Akt and MAPK signaling cascades that drive cell growth and proliferation

This, coupled with the new buccal fat removal trend which is when the fat in your cheeks are removed to achieve a more defined facial structure that so many people are getting, is leaving so many looking decades older than they really are
