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.

Growing scientific evidence suggests that highly processed foods are associated with increased risk of disease. Until recently, scientists were unable to study directly the effects of highly processed foods on humans. In this episode, we review one of the first highly controlled scientific trials demonstrating that ultra-processed foods lead to weight gain. #diet, #weightloss, #science, #fitness, #food Neuroscience of appetite regulation: https://youtu.be/i3RzV9vS_FA Chapters: 00:00 - Intro to Ultra-Processed Foods 00:55 - What are Ultra-Processed Foods? 02:14 - Disease & Ultra-Processed Foods 03:19 - Interventional Study 04:24 - Ultra-Processed Foods & Weight Gain 05:44 - Take-Home Points 06:57 - Outro Social & Website: Instagram - https://www.instagram.com/sterlingmdphd Twitter - https://twitter.com/sterlingmdphd Facebook - https://www.facebook.com/sterlingmdphd TikTok - https://www.tiktok.com/@sterlingmdphd Newsletter - http://eepurl.com/hQpdqT Subscribe to the Podcast: Apple Podcasts: https://apple.co/3y438C9 Spotify: https://open.spotify.com/show/5TDUK3F2sJXfnG63hSxJhT?si=40bb52e5b53f404c Google Podcasts: https://bit.ly/3Olanei References & Show Notes: http://www.nicksterling.com/ Legal: The content of this video is for general information purposes only and does not constitute the practice of medicine or any other healthcare professional services.

Ultra-processed foods have been shown to influence caloric intake, leading to weight gain via adipose tissue accumulation. Conversely, participants lost weight when switched to a diet of minimally processed foods. #fitness, #weightloss, #diet, #food , #science

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.

This is our first episode on weight gain and weight loss. In this episode, we describe how, as an industrialized nation, our food supply and environment have changed in a way that, in many cases, is mismatched with our biology as humans. We explore how these changes can lead to disease and metabolic dysfunction. We discuss how the replacement of whole foods with processed foods, as well as the addition of caloric sweeteners to most of the food items within grocery stores across the nation has preceded a rapid rise in obesity and metabolic dysfunction. In this episode, we begin to discuss some of the pathophysiology related to the consumption of ultra-processed and hyper-palatable foods as well as concerns surrounding the consumption of fructose- and glucose- containing sugary drinks. We also discussed the timelines of weight gain and loss as they typically occur over the lifespan and vary according to season. This episode sets the stage for the next episodes, which will focus on the normal fat metabolism and how it may become dysregulated in metabolic dysfunction.
