Ketones and Carbohydrates: Can they co-exist?

Ketones and Carbohydrates: Can they co-exist?

For reasons I’m still struggling to understand, the idea of “nutritional ketosis” (NK, to be distinguished from starvation ketosis, SK or diabetic ketoacidosis, DKA) is often discussed and debated in much the same way as religion or politics. Perhaps this can be said of all nutrition, which is a shame.  Nevertheless, in my continued defiance of such sensitive topics, I’d like to add another layer of complexity and nuance to this discussion.

As I’ve written about before, I’ve spent much of ...

How to make a fat cell less not thin: the lessons of fat flux

How to make a fat cell less not thin: the lessons of fat flux

I do still plan to finish the third, and perhaps a fourth, part on the “Ketosis – advantaged or misunderstood state?” mini-series.  However, a question I get often makes me realize a tiny bit of housekeeping is in order before we go there.  The question is basically a variation on this theme: Does being in ketosis automatically translate to fat loss?

For those too busy to read ahead, let me give you the punch line: No. For those who want to ...

My Quantified Self, Part I

My Quantified Self, Part I

A few weeks ago I gave a presentation at the Institute for Human and Machine Cognition (IHMC) in Pensacola, Florida.  Ken Ford, the CEO and Founder of IHMC, is a remarkable person and I could not wait to meet his team and see their research.  IHMC does cutting edge work, primarily for the Department of Defense (DoD). I had an exhilarating day which culminated with a presentation I gave to the team and also ...

Is sugar toxic?

Is sugar toxic?

I remember one of my mentors in surgical residency made a very important distinction for me.  He said, “Peter, never forget what you are getting paid to do, and what you are doing for free.”  You see, there are some aspects of being a surgeon that are not particularly enjoyable.  The hours are long.  Sometimes you’re asked to intervene in a situation where there is no hope, and you feel you may only make things worse.  A lawsuit is just ...

TEDMED 2013…now I get it

TEDMED 2013…now I get it

I just got back from the 2013 TEDMED conference at the Kennedy Center in Washington, DC.  I’ve always enjoyed watching TED talks online, but I’d never been to the actual conference.  I was told the experience is very different.  That was an understatement.  I don’t even know where to begin.  I don’t think anything I can write about this week will come close to actually sharing my experience, but I’ll try.

I was one of 50 speakers/performers, but the conference is ...

Two choices

I recently gave the keynote address at the faculty retreat of the Pennington Biomedical Research Center (PBRC) in Baton Rouge, LA.  When Eric Ravussin invited me, I could not have been more honored.  Folks not familiar with PBRC may be familiar with some of its esteemed alumni, including Drs. George Bray and Claude Bouchard, both of whom I was lucky enough to sit with and discuss everything from the death of ...
