Episode notes

My guests this week are two of the brightest minds in the health and fitness industry. The first is my own Chief Medical Officer, Tommy Wood, MD PhD. Tommy is currently working as a visiting scientist researching neonatal brain injury at the University of Washington. He received his undergraduate degree in Biochemistry from the University of Cambridge, before studying medicine at the University of Oxford.

My second guest is Chris Masterjohn, PhD. Chris earned his PhD in Nutritional Science from the University of Connecticut at Storrs, where he studied the role of glutathione and dietary antioxidants in regulating the accumulation of methylglyoxal. He has authored or co-authored ten peer-reviewed publications. His writes a blog, The Daily Lipid, and produces a podcast by the same name. You can also follow his professional work on Facebook, Twitter, Instagram, YouTube, and Snapchat (whatever that is!).

Tommy’s premise for this interview was as follows:

If you fix lifestyle and environment, can you be a lot less "strict" with your diet? For instance, are low carbers needing to be so low carb because everything else is broken?

I took that idea and invited Chris Masterjohn on to the show for a roundtable discussion that starts with a general debate on the causes of obesity and then moves on to what we can all to improve or maintain our body composition.

You should listen to this interview because unlike many others I’ve heard; it includes a broad discussion of the range of issues that we see in our practice that hold people back from their body composition goals. The first time you meet someone who plateaued in their weight loss while eating a low-carb diet you realise that it’s a bit more complicated than that.

Here’s the outline of this interview with Tommy Wood and Chris Masterjohn:

[00:03:15] "The built environment," one that facilitates eating more and moving less.

[00:07:48] You, the listeners, are already winning!

[00:08:38] The composition of our food.

[00:09:32] Upsetting set points--poor sleep.

[00:09:57] Circadian rhythm.

[00:10:07] Stress and gut health.

[00:11:36] Low-carb diets and weight loss.

Be sure to read Tommy’s response: Wood, Thomas. "If the Metabolic Winter Is Coming, When Will It Be Summer?." Metabolic Syndrome and Related Disorders (2017).

[00:12:58] Most of your stored body fat came from the fat that you ate.

[00:13:28] Calorie restriction.

[00:14:14] Insulin increases carbohydrate oxidation.
