Are you interested in REDs and low energy availability? Check out our latest work 'Does REDs exist?', which challenges the idea that low energy availability is the only etiological factor for the syndrome, and brings forward other possible explanations link.springer.com/article/10.100…

Huge congratulations to @weelunfoo on successful PhD viva defence today, it has been a pleasure to work with Wee and supervisors @columcronin @close_nutrition @jlAreta on a superb football nutrition PhD. Thanks to examiners @Sam_Moss15 @liam_anderson5

Nice end of 2025 and start of 2026. Congratulations to @erickmosqueraec for the second publication of his PhD. Stay tuned for more work on KME effects on adaptation, performance and metabolism from our group.

New publication from our group 'Ketone Monoester Supplementation Effects on a Comprehensive Cognitive Test Battery Following Non-Exhaustive Exercise' @LJMUSportSci. We show largely no measurable effect of KME on cognitive capacity in healthy young males 'link.springer.com/article/10.100…'

What happens to your muscles when you lose weight and exercise? Our new piece in @ConversationUK explains how combining an energy deficit with training may have a positive effect on skeletal muscle 🔗 theconversation.com/could-exercisi… #MuscleHealth #ExerciseScience #WeightLoss #Research

@JohnSpeakman4 @EricTopol I find baffling that the language used implies causation.

Grateful for the team behind this work @YNishimura87 @CLESpoSci H Taylor @weelunfoo @JamesyMorton @SamShep_ExSci @Jules_A_Strauss @ExercProteomics @LJMUSportSci

Overall: energy deficit + aerobic exercise may steer muscle toward a more oxidative and potentially more youthful phenotype. Proud of the team and excited for what’s next! 🚀

Excited to share that our new paper is out in The FASEB Journal after years in the making! 🎉 “Endocrine, Metabolic, and Skeletal Muscle Proteomic Responses During Energy Deficit With Concomitant Aerobic Exercise in Humans.” 🔗 faseb.onlinelibrary.wiley.com/doi/10.1096/fj…

@Bicycle_Bryan It looks great. I'd love to come. It won't work with my current schedule unfortunately!👎

🔎 Implications: Acute ketone supplementation alters systemic metabolism but does not change early post-exercise gene expression in muscle. If ketones influence adaptation, it may occur downstream (epigenetics, proteomics) or with different timing/duration.

🚴‍♂️ New publication in Eur J Appl Physiol! We tested whether ketone supplements change skeletal muscle gene expression after endurance exercise. Spoiler: They don’t. 🧵👇
