The key mechanisms include: Appetite suppression: Semaglutide acts on hypothalamic centers in the brain to reduce hunger and increase satiety Delayed gastric emptying: Food moves through the stomach more slowly, prolonging the feeling of fullness Improved insulin sensitivity: Better glucose regulation reduces insulin-driven fat storage Reduced food reward signaling: Semaglutide appears to decrease the neurological reward response to food In the STEP 1 clinical trial, participants receiving semaglutide 2.4 mg weekly lost an average of 14.9% of their body weight over 68 weeks compared to 2.4% with placebo (Wilding et al., 2021, New England Journal of Medicine )
Additionally, variations in dosing equivalence, species-specific GLP-1 receptor expression, and metabolic responsiveness further complicate the direct translation of these findings to human diseases (De Giorgi et al., 2025)
The fact is that both methods involve the same active ingredient, which means they work identically by activating the GLP-1 receptors in your brain and gut
