### Semaglutide Mechanism of Action Semaglutide achieves **weight loss** through multiple complementary pathways: - **Central appetite suppression** acts on hypothalamic GLP-1 receptors to reduce hunger and increase satiety - **Delayed gastric emptying** slows stomach emptying, prolonging feelings of fullness - **Improved insulin sensitivity** reduces insulin resistance and promotes healthy glucose metabolism - **Reward pathway modulation** reduces cravings and food-seeking behavior by acting on mesolimbic dopamine circuits - **Potential direct effects on adipose tissue** emerging research suggests GLP-1 may directly influence fat metabolism For a complete breakdown of semaglutide's dosing protocol, see our [semaglutide dosing schedule week-by-week guide](/guides/semaglutide-dosing-schedule-week-by-week-guide)
These clinics can provide medical evaluation, prescribe FDA-approved peptides when appropriate, and monitor your progress
Without adequate protein intake and resistance training, a meaningful portion of the weight lost on semaglutide may come from muscle rather than fat
In addition, hydroxocobalamin may be used as part of the treatment for cyanide poisoning (as an antidote), although in such emergency cases very high doses are administered under hospital care
