I had a great time talking to fellow Optimiser Debra Cleveland about her journey through the Data-Driven Fasting Challenges and Masterclasses. During our live Q&As, Debra was always full of enthusiasm, inspiration, and positive energy as she learned to nourish her body instead of depriving it. This stuck out to me, and I wanted to chat with her to …

Paul Burgess has been a great mate, supporter, and mentor throughout my journey to quantitatively define optimal nutrition. When he first invited me on his podcast, I put him off. I felt I still had more work to do before promoting what we were doing at Optimising Nutrition (and also felt a strong sense of imposter syndrome). I’ve now had the privi…

It was an honour to chat with Mark Schatzker about his new book, The End of Craving: Recovering the Lost Wisdom of Eating Well. I’ve been a MASSIVE fan of his work since reading The Dorito Effect: The Surprising New Truth About Food and Flavor. Many diet authors blame the obesity epidemic on a single smoking gun (e.g. carbs, fat, tasty food etc.). …

This chat with Matty Lansdown was part interview, part therapy session as I’ve been working on focusing on getting the essential things done in a world designed to distract and monetise your attention. I hope this episode of the Optimising Nutrition Podcast will inspire you to kick start the habits you want to build to empower you to move towards y…

What really underpins our beliefs about nutrition and the food we eat? The truth might shock and surprise you! Our nutritional guidelines and beliefs about food reflect a mixture of cultural, ritual, and religious beliefs and biases, overlayed by financial gains and food propaganda disbursed by manufacturers. But the influence of the Seventh Day Ad…

There is plenty of debate about how we can feed a rapidly growing population in a way that is healthy for us and our fragile planet with limited resources. Diana Rogers and Robb Wolf recently weighed into the debate. Their book Scared Cow proposed that, rather than doubling down on an industrial, agricultural system that created the problems we are…

Perhaps even more than weight loss, the transition women experience as they transition through middle age is one of the hottest topics in our Data-Driven Fasting Facebook Group. Not only do blood sugars, cravings and insulin sensitivity change across the month, but the changes that occur during menopause can make maintaining a healthy weight and vi…

2xTED speaker and host of the popular Everyday Wellness Podcast Cynthia Thurlow had just finished writing the manuscript for her new book specifically on intermittent fasting for women when we recorded this chat. In a world where more often equals better, Cynthia delivered a ton of practical and pragmatic information to help women navigate this oft…

I’ve been super excited to see the change in direction recently at Diet Doctor.

It was fun to chat with Andreas about his recent learning…

It was such a pleasure to speak with Lisa about her journey through Data-Driven Fasting and the Nutritional Optimisation Masterclass. In the past, Lisa said she made abysmally slow progress with Weight Watchers and got rejected from the super-expensive Spark People program for being too broken! Then, after her husband suggested she was taking way t…

Lori is one of the primary reasons that I created DDF. One of the first articles I wrote on Optimising Nutrition five years ago detailed how to use your glucose as a fuel gauge to optimise your fasting routine. Lori found this a couple of years ago and put it into practice. Over the past few years, Lori kept contacting me to tell me how well it had…

Brian Sanders is like my nutrient density brother from another mother. We spoke recently about a range of our favourite topics for his podcast, and he was telling me all about his trip to Tanzania to visit the Masia and Hadza people.

Mike Julian has been a great friend and taught me a LOT over the past six years or so!

We covered: Why he now believes the Carb Insulin Hypot…
