How do some cultures stay lean while still consuming high amounts of carbohydrates?

How do some cultures stay lean while still consuming high amounts of carbohydrates?

Many of you have asked this question over the past few months, and I’m sure many more of you have at least contemplated this question at some point.  I know I did.

 

For the sake of this discussion, let’s ignore the fact that the “historically” lean countries (e.g., France, Italy, Japan) are catching up to our levels of obesity and metabolic syndrome, especially in certain affluent subsets.  After all, we did get a 40 year head start on how ...

Gravity and insulin: the dynamic duo

Gravity and insulin: the dynamic duo

Last week I wrote about how carbohydrates are effectively a performance-enhancing substance, at least for certain performances in certain people.  I received many great questions, including some challenging this suggestion, which really pleases me because it demonstrates folks are thinking about tradeoffs and questioning everything.

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 one of the most important laws governing ...

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 ...
