The straight dope on cholesterol – Part II

The straight dope on cholesterol – Part II

In this post I’m going to tackle the next set of logical (at least in my mind) questions to follow up on last week’s post, Part I in this series.

Last week we addressed these 3 concepts:

     #1What is cholesterol?

     #2What is the relationship between the cholesterol we eat and the cholesterol in our body?

     #3Is cholesterol bad?

This week we’ll address the following concept:

      #4 How does cholesterol move around our body?

I want ...

The straight dope on cholesterol – Part I

The straight dope on cholesterol – Part I

 

I’ve been planning to write at length about this topic for a few months, but I’ve been hesitant to do so for several reasons:

  1. To discuss it properly requires great care and attention (mine and yours, respectively).
  2. My own education on this topic only really began about 9 months ago, and I’m still learning from my mentors at a geometric pace.
  3. This topic can’t be covered in one post, even a Peter-Attia-who-can’t-seem-to-say-anything-under-2,000-word post.
  4. I feel a bit like an imposter writing about lipidology because ...

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 to ...

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.

Is carbohydrate reduction or outright restriction “right” for everyone?  I doubt it.  Besides oxygen and water the list of “universal truths” for human health is pretty short.  Parenthetically, one can still overdose on both Continue Reading

If low carb eating is so effective, why are people still overweight?

If low carb eating is so effective, why are people still overweight?

I find myself getting asked this question, or some variant of this question, with increasing frequency as I speak and write about the Alternative Hypothesis I find most compelling surrounding obesity and chronic disease.  One implication of the Alternative Hypothesis, as you probably understand by now if you’ve been reading this blog, is that many carbohydrates, especially if consumed at the levels most Americans consume them, promote fat gain.  In other words, overweight people are not the lazy, constantly ...

Is red meat killing us?

Is red meat killing us?

“For the greatest enemy of truth is very often not the lie — deliberate, contrived and dishonest — but the myth — persistent, persuasive, and unrealistic. Too often we hold fast to the clichés of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinion without the discomfort of thought.

– John F. Kennedy, Yale University commencement address (June 11, 1962)

This is one of my favorite quotes.  Unfortunately, ...
