Introduction
Research in the field of ‘chrononutrition’ has continued to grow in the past couple of years, with some important studies being published in recent times. Chrononutrition is a research area that looks at the relationship between temporal (time-related) eating patterns, circadian rhythms, and metabolic health.
While past podcast episodes have covered various aspects of chrononutrition, the latest research has added important pieces to the puzzle and has led to both Alan and Danny updating their views on certain sub-topics.
In this episode, we look at recent research (including that from the Big Breakfast Project) and how understanding and conclusions from the field have shifted over time. Dr. Flanagan also gives some insight into the important chrono-related work published in the UK, which his doctoral work contributed to.

Connection to Previous Episodes
296: Circadian Entrainment, Chronotypes & Chrononutrition
- In this episode, Danny interviewed Alan about his area of research: chrononutrition.
- This is useful to listen back to as it explains some of the core concepts related to chronobiology and circadian rhythms.
- They discuss:
- Chronotypes: genetic vs. trained
- How feeding can entrain circadian clocks
- Circadian alignment vs. misalignment
- The inter-individual variation in response to light
- The evidence linking nutrition & circadian biology
- You can find that episode here.
