Deficit Without Decline: How Low Energy Rewires Muscle Protein and Mitochondria

Send us Fan MailIn episode #174 we discussed Dr. Jose Areta's latest research, including:How energy deficits influence muscle protein synthesis and qualityThe role of mitochondrial proteins and their upregulation during energy restrictionPractical implications for timing and periodization of caloric deficits in training cyclesHormonal signals and their interaction with muscle adaptation during energy deficitsAssociate Professor Dr. José L. Areta is a leading scholar in Exercise Metabolism and Nutrition in the School of Sport and Exercise Sciences at Liverpool John Moores University (LJMU). His research investigates how nutrition and exercise interact to influence both performance and health. He focuses on the timing and composition of macronutrients — carbohydrates, proteins, and fats — and how they affect training adaptation. José also examines the role of dietary supplements in optimizing athletic performance, as well as the endocrine and metabolic consequences of energy restriction, particularly low energy availability. He has contributed influential studies on how severe calorie deficits combined with exercise can alter muscle quality and metabolism. José’s work links cellular-level changes in muscle to practical nutrition strategies for athletes facing weight-sensitive sports or energy restriction.Please note that this podcast is created strictly for educational purposes and should never be used for medical diagnosis or treatment.Follow Jose Areta's research: Study discussed, Endocrine, Metabolic, and Skeletal Muscle Proteomic Responses During Energy Deficit With Concomitant Aerobic Exercise in Humans: https://faseb.onlinelibrary.wiley.com/doi/10.1096/fj.202502384RRIG: https://www.instagram.com/jose_l_aretaWeb: https://profiles.ljmu.ac.uk/13460-jose-aretaResearch: https://scholar.google.com/citations?user=8tP0vzUAAAAJ&hl=enMentioned:A Systematic Review and Meta-Analysis on the Association and Differences between Aerobic Threshold and Pint of Optimal Fat OxidationCreatineBeta-alanineSupplements that Improve Performance CourseMORE NRApply to work with Kyla → https://p.bttr.to/3ZrwzcFUse code NEWPOD10 for 10% off our meal plans → https://nutritional-revolution.com/products/CONNECT Instagram → www.instagram.com/nutritionalrevolutionSponsorship inquiries → [email protected] in having your biomarkers or nutrigenomics checked?
