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 ...

Do calories matter?

Do calories matter?

In a word, yes.  But, technically this is the wrong question.  The correct question is probably closer to, “What is the impact of the calories I consume on my body’s ability to store fat versus burn fat?

The immediate follow-up question to some variant of this first question is, “Should I be counting calories?” In a word, no. But you’ll want to read this post fully to qualify that answer.

Before I answer these important questions, let’s spend a few moments reviewing ...

Why Weight Watchers is actually a low carb diet

Why Weight Watchers is actually a low carb diet

Invariably I get asked the question, “If carbohydrates are so bad, why did [so-and-so] lose weight on the [such-and-such] diet?”, where “such-and-such” diet is not a “low-carb” diet. Obviously, this is an important question and a pretty complex one.

There are several layers to this and, frankly, there are some things we can’t fully explain – I’ll always acknowledge this. That said, many of the successes (at least weight-wise, though hopefully by now you realize there is much more to health ...

My pet peeve

My pet peeve

A few months ago someone forwarded me a clip from The Dr. Oz Show where Dr. Oz and Gary Taubes were having a discussion about the merits of carbohydrate restriction.   You can read about it here.

Yes, I get it — much of this sort of TV stuff is for entertainment purposes.  The problem, however, is that folks like us watch these shows and can’t help but be “influenced” by the banter and bravado.   So, ...

Irisin: The magic exercise hormone?

Irisin: The magic exercise hormone?

On January 11 an article was published in the NY Times Health blog section titled, “Exercise hormone may fight obesity and diabetes.”  The article reports on a recently published study in the journal Nature, the abstract of which can be found here.

The authors present research linking a hormone secreted during exercise to the conversion of white fat (white adipose tissue, WAT) to ...
