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 ...

The great medical disconnect

The great medical disconnect

There is probably no greater disconnect in medicine than the root cause of obesity.  Even if you think you already know the answer to this “obvious” question, it’s still worth reading on.  The reason this question matters, of course, is clear to everyone.  Obesity (and more broadly the syndrome we define as metabolic syndrome) predisposes us to virtually every disease afflicting us in the modern age.  Above is ...

What I actually eat (circa Q4 2011)

What I actually eat (circa Q4 2011)

Note to readers: This post was written in December of 2011.  PLEASE do not ask me why I eat ‘this’ or why I don’t eat ‘that’ — as what is shown here does not necessarily reflect what or how I eat today (or more importantly, how you should eat).  My diet evolves constantly, due to my constant tweaking and self-experimentation. Over time, I’ll share it here and there, but what I eat is not at all the focus of this ...

What is cholesterol?

What is cholesterol?

I know much more about cholesterol today than I did even two years ago, let alone when I was mindlessly reiterating “standard” cholesterol recommendations to patients years ago.   You can’t talk about nutrition without mentioning cholesterol, but most folks (including many of the doctors who tell you yours may be too high) don’t know what cholesterol actually is, let alone the actual risk it portends.  I’m going to be doing a lot of writing about the confusion over cholesterol in ...

You are not what you eat

You are not what you eat

You are what you eat, right?  How many times have you heard this?  I’d need scientific notation to actually enumerate the number of times I’ve heard this statement or one like it.  I certainly spent most of my life believing this, too, without ever questioning it. In fact, this you-are-what-you-eat dogma plays a significant role in our misguided belief that fat is bad for us.

So let’s examine this “dogma” and let’s use an average person as an example:

  • Assume you consume ...
