Summary
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 lead to both Alan and Danny updated 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 work published in the UK, which his dotoral work contributed to.

| 0:00.0 | Hello, and to another episode of Sigma Nutrition Radio. This is episode 469 of the podcast. My name is Danny Lennon and I'm here with Dr. |
| 0:24.7 | Alan Flanagan. Alan. We are going to cover the topic of chrono-nutrition, which we have done so |
| 0:30.3 | in quite some detail in previous episodes of the podcast as well as in other forms. And of course |
| 0:35.8 | there's been some specific episodes on niche topics within that as well as in other forms. And of course, there's been some specific episodes on niche topics |
| 0:39.5 | within that, as well as some big overview level episodes. And I'll link to some of those past |
| 0:43.8 | episodes in the description box if anyone is new to the podcast or maybe hasn't heard those. |
| 0:49.6 | But the goal today is to maybe give an update on our position on some of these things, |
| 0:56.0 | talking about either some new research that has came out over the last year or two, |
| 1:00.5 | how that has influenced some of the conclusions we can come to, |
| 1:03.8 | and how that maybe has potentially changed what conclusions we can make going forward in practice |
| 1:10.0 | based on the current evidence base. |
| 1:12.6 | So with that in mind, it might be useful to start with either an intro to chronobiology generally, |
| 1:19.6 | for people maybe first hearing this, or for people who have listened to our past episodes, |
| 1:24.6 | a refresher of some of the key terms and ideas that relate to this topic |
| 1:29.0 | of chrono-nutrition, which of course is this branch underneath chronobiology. |
| 1:34.3 | So, Alan, given this is an area directly related to your research, what is the best way to |
| 1:41.3 | maybe introduce some of those terms to people around chronobiology, |
| 1:45.1 | circadian rhythms, and then how there's a connection to eating and essentially this field |
| 1:50.3 | of chronon nutrition, what we're actually talking about? Yeah, so the concept, chrono, obviously, |
| 1:54.7 | meaning time. So, you know, the overall field of chrono-nutrition is really the study of the interaction between our biological rhythms, circadian rhythms, in metabolism and other rhythms, behavior, and the interaction with behavior as well. |
| 2:13.2 | I'll explain what we mean by circadian and behavioral rhythms. |
| 2:16.6 | It's the interaction with those |
