SUMMARY OF EPISODE

In Season 4, Episode 15 Dr. Marc Bubbs interviews expert physiologist Dr. Rob Edinburgh, PhD whose area of interest includes meal timing and exercise to discuss…

3:00 – Rob’s background in nutrition and research

5:15 – Review of energy balance: energy intake and expenditure

6:10 – What is metabolic health?

13:15 – Effects of skipping breakfast (versus eating breakfast) on exercise adaptations

17:30 – Energy balance over a 24-hour period in breakfast vs. skipping breakfast

21:30 – How does intensity training impact the results of the study?

23:30 –How does ‘breakfast timing’ impact exercise adaptations in overweight and obese individuals

28:30 – Meal + exercise interactions - acute responses to exercise

31:40 – Metabolic benefits of exercising in the fasted-state (in healthy people)

36:30 – The main pathways via which exercise supports better health: AMPK, PGC1-alpha

42:30 – Energy Balance: weight loss and health vs. performance

45:45 – The use of intra-muscular triglyceride during fasted exercise

About Dr. Rob Edinburgh, PhD  

Rob graduated from the University of Bath in 2015 with a first class honours in Sport and Exercise Science (BSc), winning the David Wilkinson prize for the best physiology student. Rob is particularly interested in how exercise and nutrition can counteract the increasing worldwide prevalence of diseases such as obesity and type 2 diabetes. Rob has also worked at the PEAK Centre for Human Performance in Ottawa (Canada) as an Exercise Physiologist, where he led individualized consultations on exercise and diet, performed exercise tests and ran strength and conditioning classes.
