This means that only a small fraction of the drug reaches the bloodstream, necessitating higher doses or special formulations in order to achieve the desired therapeutic effect
The four-pathway model therefore targets appetite (GLP-1 and amylin through separate neuronal circuits), fat metabolism (GIP and glucagon), energy expenditure (glucagon primarily), and glucose homeostasis (GLP-1, GIP, and amylin all contribute through different mechanisms)
Traditional obesity intervention strategies (e.g., dietary control, exercise, conventional weightloss drugs) are often limited by slow onset, obvious side effects, and high rebound rates, and can hardly fundamentally reverse the abnormal metabolic phenotype of adipose tissue
