Is there a way to exploit the metabolic quirk of cancer?

Is there a way to exploit the metabolic quirk of cancer?

One night, as I alluded to in this post, Tim and I were having dinner and the topic of cancer came up.  Personally and professionally I have a great interest in cancer, so when Tim asked if I could write something about cancer that was: (i) interesting to a broad audience, (ii) not technically over the top, (iii) not my typical 5,000 word dissertation, (iv) yet nuanced enough for his readers, I agreed ...

Ketosis – advantaged or misunderstood state? (Part II)

Ketosis – advantaged or misunderstood state? (Part II)

When I wrote part I of this post, I naively assumed this would only be a two-part series. However, so many great questions and comments emerged from the discussion that I realize it’s worth spending much more time on this important and misunderstood topic.

The Fat Trap, NYT Magazine article – thoughts and comments

On January 1, NY Times wellness columnist, Tara Parker-Pope, wrote an article in the NYT Magazine titled The Fat Trap, and many of you forwarded it on to me. This was an excellent piece and I suspect it will be one of the most read pieces this year in the wellness space.

Ms. Parker-Pope acknowledges that weight loss is very difficult and the rate ...

Revisit the causality of obesity

Revisit the causality of obesity

My last post addressed a point that has historically (and currently) led to great confusion – the idea of what causes obesity.  In the previous post, discussing what I call “the great medical disconnect,” I wrote about obesity (i.e., unregulated horizontal growth) being caused by excess insulin, which in turn leads to overeating and under-moving.  This is contrasted with the reverse – overeating causing obesity.  Let’s double-click on this idea using ...
