Beginning with a discussion on the evolution of these medications, Dr. Bikman emphasizes their significance in combating obesity-related health issues. He proceeds to analyze the mechanisms of popular weight loss drugs, such as Orlistat, Phentermine, and the combination of Phentermine with Topiramate, elucidating how each functions to aid weight loss.
While highlighting the benefits, Dr. Bikman doesn’t shy away from detailing the potential side effects, ensuring a comprehensive understanding for the audience. Moreover, he shares an intriguing scientific fact regarding lactate’s role in fat metabolism, adding depth to the discussion. Throughout, Dr. Bikman maintains a balance between scientific evidence and personal insight, fostering an engaging and informative session.
In discussing liraglutide’s mechanism of action, Dr. Bikman reveals its role as a GLP-1 receptor agonist, mimicking the actions of the incretin GLP-1. He then previews next week’s class dedicated to incretins and their use in weight loss drugs, including medications like wegovy and ozempic.
Liraglutide primarily promotes weight loss by reducing gastric emptying, leading to prolonged feelings of fullness and decreased appetite. Additionally, it inhibits glucagon, lowering blood glucose levels and subsequently increasing metabolic rate and fat burning. Dr. Bikman notes common side effects such as gastrointestinal discomfort and hints at potential risks of thyroid tumors associated with GLP-1 agonists.
Ben transitions to discussing semaglutide, another GLP-1 receptor agonist, and its similar effects on weight loss and side effects, including the possibility of ileus. He also touches on metformin’s off-label use for weight loss, its mechanisms involving AMPK activation and ATP inhibition, and its potential interference with exercise-induced mitochondrial benefits.
