Reduce Your Biological Age: The Science of Living Younger for Longer

In this episode of Eat Nourish Love, Caroline Cary is joined by Leslie Kenny, former international banker and Walt Disney executive turned longevity entrepreneur, and founder of Oxford Healthspan.In her late 30s, Leslie was diagnosed with lupus, rheumatoid arthritis and later Hashimoto's thyroiditis, and told there was no cure and perhaps five years left. Refusing to accept that, she rebuilt her health through nutrition, lifestyle and a deep dive into cellular science, went into remission within six months, and conceived naturally at 43 after being told it was impossible.Her story will resonate with anyone who has been dismissed by the system, handed a label instead of an answer, or told it is simply too late.About Leslie KennyLeslie Kenny is a longevity entrepreneur and the founder of Oxford Healthspan. A UC Berkeley graduate with a Harvard MBA, she began her career in Swiss banking before joining Walt Disney, where she was handed its then unprofitable internet division and went on to launch one of the first online matchmaking companies in China and across Asia, working directly with the Chinese government on early public health education. After transforming her own health following an autoimmune diagnosis, she partnered with scientists affiliated with the University of Oxford to make science-led, food-derived longevity solutions more widely available. What This Episode traces the path from a high-stress, sedentary corporate life to the "perfect storm" that preceded her illness, and the moment a doctor advised her against another round of IVF because she had five years left. She explains the mindset that changed everything: aiming to be just 1% better each day, and throwing the kitchen sink at her own recovery.The conversation then turns to the science Leslie built a company around: spermidine, a food-derived compound studied at Oxford for its role in autophagy, the body's cellular self-cleaning process. She explains how it renews ageing immune cells, why fasting alone may not trigger cell renewal without it, which everyday foods contain it, and how it differs from weight-loss drugs and HRT. They also cover biological age testing, hormone balance, and the mission of the Oxford Longevity Project.Resources and MentionsSpermidine research at the University of Oxford, Kennedy Institute for Rheumatology.Dr Barry Sears, The Anti-Aging ZoneGerald Epstein, Healing VisualizationsBiological age tests mentioned: GlycanAge and the Dunedin PACE testDr Barry Durrant-Peatfield, thyroid specialistContact Leslie KennyOxford Healthspan: oxfordhealthspan.comInstagram: @lesliesnewprime Oxford Longevity Project: oxfordlongevityproject.comInstagram @oxfordlongevityproject Leslie's Three Key Takeaways:Move. We were never designed to be sedentary, yet laptops, screens and video calls conspire to keep us still. Movement, not too much and not too little, is foundational.Nourish. Not just good food and water in the right amounts, but social connection, a sense of purpose, volunteering, good sleep and stress reduction. All of it is nourishment.Renew. Trigger the body's self-renewal through autophagy, and get yourself into a parasympathetic state where you feel safe enough to rest, repair and restore. Unresolved stress and trauma keep inflammation lingering, so renewal matters as much as diet and movement.About Eat Nourish LoveEat Nourish Love Podcast is your go-to space for wellness, self-care, and inspiring stories.
