In Episode #174, a condensed throwback to Episode #119, we hear from climate scientist Dr Jonathan Foley on the current state of climate change and what we can do to help the planet heal. We discussed where we are headed if we don’t address climate change, what we can actually do about it, and the biggest areas of focus for immediate change. The episode also covers topics such as how climate change science is becoming accepted by the majority of society, climate change solutions affecting people’s careers, the current status of the world’s carbon emissions, and much more.

Some people follow a ketogenic diet seeking to lose weight, feel more energised, or gain control over their eating habits. Others may turn to this diet in an effort to treat conditions such as epilepsy, bipolar disorder, diabetes and inflammatory diseases. Regardless of their reasoning for adopting this eating pattern, a key question remains: is there ever an instance where having high LDL cholesterol levels on a ketogenic diet can be safe? In Episode #311, I’m joined by Dr William Cromwell, MD and Dave Feldman to explore this question.
In this discussion, Dr William Cromwell and Dave Feldman share their professional opinions on whether high cholesterol on a keto diet is a problem. We investigate where their opinions align and where they differ, where Dave’s hypotheses diverge from the norm, and what we do and don’t know with the available evidence. We also explore the significance of ApoB, lifespan and healthspan considerations, research Dave is currently conducting, and much more.

Episode #308. How would Jesus kill an animal? Join me as I sit down with filmmakers Kip Andersen and Kameron Waters to discuss their position on how religion and veganism intersect. Whether you are religious or not, there are many interesting points raised to reflect on further.

Religion, spirituality and eating animals | Kameron Waters & Kip Andersen

Episode #307. According to Robin Sharma, eight factors define wealth – and only one of them is money. Join me in today’s episode as I sit down with this leadership expert and bestselling author to unpack what it truly means to be wealthy.
You’ll learn about what happy people have in common, how to find more fulfilment, and how to perform a full reset on your life. Robin pulls back the curtain to offer a glimpse of what his habits look like and how you can implement habits to help you become your best self. Plus, discover why you should consider eating out alone, why you should be thinking about death, and plenty more in this insight-packed conversation.
In any conversation considering the relationship between money and happiness, it’s important to note that not everyone has the time or resources to commit to self-improvement. If you’re in this camp, you’re far from alone. My advice would be to take the core principles discussed in this episode and find some goals that are reasonable for you. Even if you can only set aside fifteen minutes a day, any steps you can take have the potential to make a big difference in the long run.
