GLP-1 agonists are pharmaceutical interventions with potent systemic signaling
GLP-1 agonists produce dramatic weight loss (averaging 15-20% total body weight) primarily through central appetite suppression, eliminating hunger and creating pharmaceutical satiety
These include smoking, excessive coffee or alcohol consumption, diabetes, rheumatoid arthritis, thyroid disorders, coeliac disease, Crohns disease, obesity, physical inactivity, chronic stress, and certain long term medications such as proton pump inhibitors and corticosteroids
