Hey Peter, what does your daughter eat?

If there’s one question I get asked often, it’s this one.  And I understand why.  Anyone who knows me, and knows how obsessed I am with everything I do, knows there is one thing on earth I cherish more than anything else – my daughter.

What does lower back pain have in common with low carb eating?

Strange question, huh? Before you get too excited, I’m not about to tell you that a low carbohydrate diet is a remedy for back pain.  Instead, I am going to explain a remarkably parallel experience I’ve had. I never made the connection until this week when a reader asked an unrelated question about lower back…

The straight dope on cholesterol – Part IX

In this post we’ll address the following concept: What should you eat to have the greatest chance of delaying the arrival of cardiovascular disease?

Good science, bad interpretation

In 2012, the Journal of the American Medical Association (JAMA) published a study entitled Effects of Dietary Composition on Energy Expenditure During Weight-Loss Maintenance. While I’m guessing most readers have not read this study, I’m pretty sure most of you have heard about the results as it was all over the news this week. I was fortunate…

Metabolic disease

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.

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.

Philosophiae naturalis

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…

Ketosis

The interplay of exercise and ketosis – Part I

I embarked on a self-experiment last weekend to see if I could better understand the interplay between the different types of exercise I do and ketone production (beta-hydroxybutyrate, or B-OHB, to be specific).  To be clear, nothing I do with a sample size of one “proves” anything, but sometimes self-experiments can help you formulate hypotheses…

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.

Biochemistry

How can carbohydrate restriction be healthy if it means limiting “natural foods” like fruits and vegetables?

This week I’d like to tackle one of the most important questions that I get asked.  However, before getting to the question, I think it’s worth investing a few minutes to frame this discussion around a theme tightly linked to it — sugar.
