Mini Mikkipedia - When GLP-1 Weight Loss Dims Motivation

This episode explores emerging evidence that high-dose tirzepatide may reduce more than appetite and food noise in some people. Mikki breaks down a new case series involving three women who experienced anhedonia, a loss of motivation or interest in previously rewarding activities, despite achieving substantial weight loss. She explains the difference between “wanting” and “liking,” how GLP-1 medications may influence dopamine reward pathways, and why symptoms can feel different from depression or early medication side effects. The cases suggest that dose reduction may restore motivation without necessarily compromising weight-loss maintenance. While three cases cannot establish causation or prevalence, the findings highlight the importance of monitoring exercise, hobbies, social engagement, and overall enjoyment alongside weight, appetite, and gastrointestinal symptoms.Topics CoveredWhat anhedonia is and how it differs from depressionThree cases involving high-dose tirzepatideThe potential role of dopamine and reward pathwaysWhy dose reduction improved symptoms in these casesPractical considerations for patients and prescribers Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenNZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzSave 20% on all Nuzest Products WORLDWIDE with the code MIKKI at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comCurranz supplement: MIKKI saves you 25% at www.curranz.co.nz or www.curranz.co.uk off your first order
