S 937: Battle of the GLP-1s: Semaglutide vs Tirzepatide vs Retatrutide

<p>Semaglutide, Tirzepatide, and Retatrutide are often grouped together as GLP-1 medications, but they are not simply three versions of the same drug. In this episode, I compare the biology, research, and real-world implications behind each compound, looking beyond the number on the scale to ask a more useful question: what type of weight is being lost?</p><p>I break down the progression from single agonist to dual agonist to triple agonist, including how GLP-1, GIP, and glucagon signaling may influence appetite, glucose regulation, energy expenditure, and fat loss. I also examine what the available body composition research shows about lean mass, visceral fat, skeletal muscle, and the risk of becoming lighter without becoming healthier or stronger.</p><p><br></p><p>Topics discussed: </p><p>- What actually separates the major GLP-1 medications</p><p>- The scale </p><p>- The body composition </p><p>- Current evidence about retatrutide</p><p>- Muscle prevention </p><p>- Framework for evaluating weight loss outcomes</p><p><br></p><p><br></p><p>---------- </p><p><a href="http://www.metabolismschool.com/">⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠My Live Program for Coaches: The Functional Nutrition and Metabolism Specialization ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠</a></p><p><a href="http://www.metabolismschool.com/">⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠www.metabolismschool.com⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠</a></p><p>---------- <br>[Free] Metabolism School 101: The Video Series<br><a href="http://www.metabolismschool.com/metabolism-101">⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠http://www.metabolismschool.com/metabolism-101⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠</a><br>----------<br>Subscribe to My Youtube Channel: <br><a href="https://youtube.com/@sammillerscience?si=s1jcR6Im4GDHbw_1">⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://youtube.com/@sammillerscience?si=s1jcR6Im4GDHbw_1⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠</a><br>----------<br><a href="https://metabolismmadesimple.com/">⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Grab a Copy of My New Book - Metabolism Made Simple⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠</a><br>----------<br> Stay Connected: <br><a href="https://www.instagram.com/sammillerscience/">⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Instagram: @sammillerscience⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠</a><br><a href="https://www.youtube.com/channel/UCKi5AgCKH37irVYvlIYC-vA">⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Youtube: SamMillerScience⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠</a> <br><a href="https://www.facebook.com/groups/nutritioncoachingcollaborative">⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Facebook: The Nutrition Coachi
