How “Ozempic” Works – Weight Loss, Weight Regain, & Neuroscience

How do drugs like Ozempic (semaglutide) cause weight loss? What happens when someone comes off of these drugs? In this episode, we discuss how these drugs (GLP-1 receptor agonists) target specific areas in the brain to suppress appetite and facilitate weight loss. We also discuss clinical trials data suggesting that these drugs and/or the weight loss that they facilitate may have cardioprotective effects. Lastly, we will also examine evidence regarding weight regain when coming off of these drugs and common side effects.

How Super-Athletes Use FAT for Fuel

In this episode, we discuss fat through the lens of performance and survival, and what happens when we push our energy systems to their limits. We also talk about how our bodies make adaptations via exercise to improve our ability to “burn” fat for fuel, and how our bodies conserve fuel during times of negative energy balance. Lastly, we preview the role of fat as an endocrine organ and the importance of its communication with the brain, as well as the critical role of exercise capacity for our future health.
