  • Simply superb

    Zoe‘s podcasts are amazing. The people she talks to are not only brilliant in their expertise and understanding, but also wonderful at explaining things. I have been a type one diabetic since I was 16 and have been given the wrong advice by the NHS ever since. The minute I finished listening to the podcast with Jon Furniss, I immediately made changes to my regime which have already improved my sugar control. I can’t believe how measured Jon was when asked the question about what advice he had re... more

Talking Points

Recent interactions between the hosts and their guests.

Zoë and Dr Ty Beal discuss the evolution of nutrient profiling systems
Q: What concerns or criticisms do you encounter about the system, and how do you respond?
Critics come from both plant-based and carnivore ends; we acknowledge those viewpoints, explain that the system is adjustable and not rigid, and emphasize that it aims to balance nutrient density with real-world dietary patterns and environmental considerations.
Zoë and Dr Ty Beal discuss the evolution of nutrient profiling systems
Q: How did you approach data limitations when building the database for real foods across diverse contexts?
We started with foods from low- and middle-income countries, built comprehensive datasets from various food composition databases, and filled gaps using available sources and collaborative work with partners like Megan O'Hern; we also extended coverage to ultra-processed foods based on reviewers' input.
Zoë and Dr Ty Beal discuss the evolution of nutrient profiling systems
Q: Could you explain the difference between the nutrient density score and the nutritional value score?
The nutrient density score focuses on vitamins, minerals, protein, and omega-3s to reflect essential nutrient content, while the nutritional value score also incorporates ratios and other factors like fiber, calories, and components related to non-communicable disease risk, giving a broader view of how foods influence health.
Obesity, weight loss, hunger & hormones with Dr Jason Fung
Q: Why do you argue that hormones, not calories, drive weight change?
Because hormones like insulin, cortisol, and GLP-1 determine whether calories are stored or burned and can override simple calorie totals; the body's response to food depends on hormonal signals, not just the amount eaten.
How and why Insulin Resistance drives chronic disease with Dr Isabella Cooper
Q: Could you explain insulin resistance and hyperinsulinemia to listeners who may not be familiar with those terms?
Insulin resistance is largely about glucose uptake in response to insulin signaling. In such states, insulin is often higher than normal and promotes growth signals in cells, while glucose uptake is impaired. This state can drive proliferation and suppress apoptosis in certain tissues, contributing to disease risk even when blood glucose looks relatively normal.
