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.
- Chronobiology & circadian rhythms
- Eating at biological night results in different postprandial metabolism than eating during the day
- Eating at night could impact circardian rhythms
- Circadian rhythmicity to beta-cell function, insulin sensitivity, etc. could alter response to meals
- Length of feeding/fasting
- Calorie distribution: Higher % of calories at end of day could be more negative?
- Associational work looking at mid-point of calorie intake and sleep time
- Impact of meal timing on TEF
- The impact of the timing has to be considered in the context of melatonin
