The Source — Issue 0: The Anti-Optimisation Issue.
Across EAT, MOVE, MIND, and SLEEP, Healf’s editorial team brings together writers, experts, scientists, thought leaders, and cultural icons to cut through the noise — and find what actually lasts.
The path to wellbeing is often a whole lot simpler than we're led to believe.
The Source is Healf's premium print magazine — a place to learn, ask questions, and discover why wellbeing is not one-size-fits-all. Through long-form features, expert profiles, wellbeing guides, and product curations, this inaugural issue takes on anti-optimisation, tapping into the idea that the future of wellbeing might well mean looking to the past for guidance. In this vision of the future, the cutting edge complements the cornerstones, and modern science makes room for ancient rituals.
Inside this issue:
The Death of Diet — Whether you’re cutting carbohydrates, fasting until midday, or eating like a caveman, most of us have been taught that the solution to our health lies in following a rigid framework of rules — a “diet”. This feature does a deep dive on the diets of today, and how our vision around them is evolving to nourish rather than restrict.
F*ck Fitness — Regimented markers like calorie burn and heart rate are being swapped out for more dynamic, complex metrics like flexibility and mobility. We’re leaning into strength training and zone 2 cardio, and finding things that work for our bodies.
The End of Optimisation — Wearables promised to make us healthier. For many of us, they’ve just made us more anxious. This feature explores the ways anti-optimisation culture is changing how we think about the future of health.
A Circadian Revolution — The fundamentals of good sleep haven’t changed for millennia, but the world around them has. We’re uncovering the hidden mechanisms that prevent good sleep, and exploring ways to combat them.
Fact vs. Faith — If Andrew Huberman, whose entire platform is built on peer-reviewed science, thinks faith has health benefits and should be taken seriously, it’s probably worth asking what the science of faith actually says.
Calvin Harris: The Rhythm of the Road — In this profile, you’ll meet the version of the world-famous DJ who can make a gruelling schedule survivable, while still being refreshingly low on mysticism.
Claudia Schiffer: Remodelling Wellbeing — In this profile, the supermodel and global fashion icon shares her insights on ageing well, women’s health, daily rituals and routines, and her favourite everyday essentials with Healf.
Dr. Tara Swart: The Neuroscience of Intuition — Dr. Swart explores how gut feelings live in our body. They’re not just passive thoughts or random feelings, but a biological process that signals what your body recognises well before your mind catches up.
Contributors: Jess Bantleman, Ben Callon, Hannah Coates, Ed Cooper, Alexia Demetriades, Currie Engel, Rose Ferguson, Isobel Lewis, Samantha Nice, Tom Ward — with photography by Felicity Ingram, Kelly Louise, Daniel Farò, and Julien Tell.
