Beyond willpower: The biology of hunger | Sarah Kennedy

Weight-loss drugs that target the hormone GLP-1 have rapidly reshaped the conversation around obesity, appetite and personal responsibility. But alongside the rise of powerful synthetic injectables, researchers are also exploring whether the body’s own appetite signals can be harnessed more naturally. At the heart of the debate is a simple question: are we eating too much because of weak willpower, or because of biology? As new approaches emerge, the challenge is to balance effectiveness, safety and long-term sustainability in tackling one of modern health’s most persistent problems.In this interview, Sarah Kennedy, founder of Calocurb, a New Zealand company which has developed a plant-based compound designed to naturally stimulate GLP-1, discusses the science of appetite control and how it compares to injectable drugs. ---------------Try Calocurb for yourself?Get a 10% discount HERE---------------This podcast is supported by affiliate arrangements with a select number of companies.

Artificial intelligence is rapidly changing how we understand our health — not just how we feel today, but how fast we’re actually aging.On this episode of Live Long, host Peter Bowes continues his personal experiment with Hundred, the AI-powered longevity platform that combines advanced blood testing, wearable data and personalized insights to track biological age and guide smarter health decisions.After introducing the app in an earlier conversation, Peter reconnects with Hundred’s founder, Tyler Smith, to go deeper into the idea of a “health operating system” — essentially a personal doctor in your pocket. Together they explore how continuous testing and AI analysis could help prevent disease, spot risks earlier, and motivate lasting behavior change — while also addressing the realities of over-testing, false alarms, privacy concerns and health anxiety.Peter also shares the results of his own first round of testing, what surprised him most, and how he’s using the data to shape his approach to longevity and healthy aging.-----JOIN HUNDREDOptimize your healthspan and potentially lower your biological age.  Tyler and the team at HUNDRED are offering $75 in credit for add-on tests and supplements from the HUNDRED marketplace when you sign up at hundred.com/livelongpodcastThis podcast is supported by affiliate arrangements with a select number of companies.

Was it a boozy start to the New Year? What if you could gain more clarity, energy, and better health by giving up drinking? Imagine a day when alcohol no longer dominates our thoughts—at holidays, celebrations, or even a quiet night in front of the TV. Alcohol-free expert James Swanwick says a cultural shift is underway, with alcohol slowly losing its grip on our social and professional lives. Even moderate drinking can quietly sap sleep, focus, and long-term wellbeing—especially for high achievers. In this conversation, Swanwick explains the neuroscience of addiction, why going alcohol-free is gaining momentum, and how the stigma around teetotalism is fading. He predicts that within decades, alcohol could be viewed with the same disdain as cigarettes.-----This podcast is supported by affiliate arrangements with a select number of companies.

Mind–body training is widely recognized as a pillar of healthy aging. Research suggests that how we move — and how we think while we move — are deeply connected. When breath, focus and technique align, we sharpen cognition, reduce stress and build the kind of resilience that keeps us active for life.In this episode of Move for Life, fitness coaches Nate Wilkins and Shebah Carfagna explore why the mind–body connection is more than a trend — it’s a practical framework for living longer and living well. From tai chi and yoga to strength training or a simple daily walk, they highlight the unifying theme of intentionality: paying attention to what the body is doing and why.Even small rituals — stepping outside for a dose of “ecotherapy,” or taking a mindful decision-making walk — can transform everyday movement into powerful brain-training moments. Studies now show that moderate physical activity can ease anxiety and depression as effectively as some medications.It’s a compelling reminder that exercise isn’t just for the body — it’s one of the most potent tools we have for lifelong mental well-being.This is the latest in our 20-part series, Move for Life. You should consult a doctor or qualified fitness professional before beginning a new exercise program, especially if you have an existing health concerns or limited mobility.-----This podcast is supported by affiliate arrangements with a select number of companies.

From the way artificial light disrupts our sleep patterns to how animals’ natural cycles offer valuable insights into human health, the science is undeniable. Dr. Philippa Gander, a leading expert in sleep and circadian rhythms and author of Life in Sync: The Science of Internal Clocks and How We’re Disrupting Them explains how these disruptions impact not just humans but entire ecosystems, including marine life. Her groundbreaking work also reveals the profound effects of light pollution, offering fresh perspectives on how we can better align our lives with our biological clocks.
