HIIT interrupts this cycle by dramatically improving insulin sensitivity and glucose uptake in skeletal muscle — particularly in the large lower-limb muscles of the thighs and glutes. A single 20-minute session of HIIT can activate GLUT-4 transporters in muscle cells for up to 24–48 hours, drawing glucose out of the bloodstream and away from storage in the liver and visceral fat depots.

Mitochondria are the power stations inside every cell, converting food into energy. But in modern life, with constant carbohydrate intake and low energy demand, they become overwhelmed. Just like solar panels producing too much electricity for full batteries, mitochondria have nowhere to send surplus fuel. This triggers oxidative stress, inflammation, and early ageing. Insulin is meant to divert excess glucose to safe storage — but when that system fails, metabolic chaos follows. In this article, we explore how your mitochondria manage energy, what causes them to overload, and how lifestyle changes can help restore balance and protect long-term health

Troponin-negative chest pain presentations are often sent home without a timely work up or prompt imaging tests like a CT angiogram. A delay can be critical. As clinicians, we must identify which patients need further testing urgently. Where clinical suspicion is high, irrespective of troponin rise doctors and health commissioners should prioritise resources, so that an accurate diagnosis can to be made. Lives literally depend on a prompt anatomic test being done in time. Until this has been made available nationally, patients experiencing unexplained chest symptoms who have not had clinical follow up and diagnosis confirmed are advised to 'vote with their feet'- either head back into hospital in event of further symptoms, or even consider arranging to fund their own urgent CT angiogram from an independent medical provider.
