My guest today is Dr Stephanie Venn-Watson, a veterinary epidemiologist, entrepreneur, and a leading expert in C15. Dr Venn Watson has conducted over 60 peer-reviewed papers and has made the link between C15 deficiency, insulin resistance, and chronic disease.
C15 is a saturated fatty acid in whole-fat foods, including whole-fat dairy, fatty fish, and red meat. Dr Venn Watson will discuss how the changes in our modern diet and the changes in dietary guidelines towards low-fat and high-carb diets have contributed to Cellular Fragility Syndrome, which leads to C15 deficiency.
Dr Venn Watson will discuss the process of Ferroptosis, which causes an iron overload in the liver, leading to chronic disease and insulin resistance. She will also discuss the amount of C15 you need, how to avoid deficiency, and the best dietary sources of C15 (hint: it includes butter).
This episode is important to understand that insulin resistance does not just come from sugar and carbohydrates, but also from C15 deficiency. You will learn the science behind C15 deficiency, how to fix it, and Fatty15 - a revolutionary new supplement to fix C15 deficiency.

You won’t lose belly fat until you do these 5 steps with Dr Sten Ekberg. Head to https://boncharge.com/theprimal and use code THEPRIMAL for 15% off.
It turns out that belly fat is not a sign that you lack willpower. It is a sign that your stress levels and insulin are out of balance. I sat down with holistic doctor Sten Ekberg to explain why standard calorie counting fails and how to fix your metabolism for good. If you want to lose belly fat without feeling hungry all day, this conversation is for you.
In this episode, we reveal:
* Insulin Resistance: Why high stress and rising insulin force your body to store stubborn fat around your stomach.
* Sugar Cravings: How blood sugar crashes trick your brain into wanting food even when you are full.
* The Calorie Trap: Why eating less and doing endless cardio just slows down your metabolism and causes belly fat and visceral fat.
* Smart Fasting: How simple meal timing lowers your insulin levels so your body can burn stored fat for energy.
* Metabolic Reset: Practical ways to fix your health so you can lose the weight and keep it off naturally without suffering.
