Twins Merge Heart Science and Ironman Grit to Revolutionize Metabolic Health

Identical twins Merav and Michal Mor have combined their expertise in heart health with a passion for endurance sports. Both earned PhDs in physiology and now run Lumen, a company focused on metabolic tracking. Their work aims to help athletes and everyday users optimise performance through real-time data. The Mor sisters studied together at the same university, specialising in cardiovascular physiology. Their research, published in journals like the Journal of the International Society of Sports Nutrition, explores how diet and exercise influence metabolism. They later turned their focus to practical applications, founding Lumen—a device that measures whether the body is burning fat or carbohydrates.

Outside the lab, the sisters share a love for triathlons. They began competing together for fun but soon took on gruelling Ironman races. Their training philosophy emphasises muscle development for strength, stability, and energy efficiency. One of their key recommendations is eating dinner earlier. This simple adjustment, they argue, helps the body burn fat more effectively and keeps blood sugar levels steady. Their device, Lumen, provides users with insights into how nutrition and exercise affect metabolic flexibility in real time.

The Mor sisters continue to bridge science and athletics through their research and technology. Their device offers a data-driven approach to improving metabolic health. Meanwhile, their shared success in Ironman competitions reflects their commitment to both performance and scientific rigour.
