I know! It’s been almost an entire year since the last episode of ClimbSci! But, this new episode (another listener Q&A session) is almost four hours long, so hopefully Tom and I have made up for our absence at least partially. The topics we cover are extensive, but run the gamut from protein and collagen […]

Skin-Based Nutrition?
Freshman year of college, my biology professor taught us about fungi. Fungi, if you are not aware, have an external digestive system; they secrete digestive enzymes to the outside of their body which break down nutrients to absorb. My professor didn’t think this was particularly impressive, though, because technically humans also have an external digestive […]

An Update on Dietary Collagen Protein
As many of you know, in the past I’ve taken a critical stance on dietary collagen protein and recommended against it as a supplement. Science evolves, however, and given the new research that has come out since I first took my stance, I thought it an appropriate time to revisit the topic and potentially reevaluate […]

Revisiting Macronutrient Ratios
I wrote an article about the “ideal” macronutrient ratios for different types of climbing a long time ago—almost four years now! It’s still a good basic overview, but I think it’s time to revisit the topic and provide a little more context. Moreover, I think it might be worth writing an article explaining some of […]

Healthy Diets, Healthy Attitudes
Tom and I finished recording an episode on weight loss recently. For many, weight loss is a sensitive topic, and while we try to approach the topic from a scientific “these are the facts” point of view, by necessity we also wade into more tangled areas of motivations, body image, and dietary control. We finished […]

The Way We Think About Diets Is All Wrong
Tom and I are preparing to do an episode of ClimbSci on weight loss, which got me thinking about diets and dieting in general. This article is a reflection on some of those thoughts. As a nutritionist, I seek out articles both scientific and mainstream to see how our understanding is changing. With science, our […]

ClimbSci Episode 10: Climbing Nutrition Priorities
In a perfect world, we would be able to “do it all”. We don’t live in a perfect world, though, and so we must instead prioritize. In Episode 10 of ClimbSci, Tom and I discuss how best to prioritize nutritional choices for climbing performance—that is, what choices will make the biggest impact (first priority), what […]

Can We Convert Fats Into Carbohydrates?
I recently received a question about the potential for humans to convert fat into carbohydrates and thought it was interesting enough to put here on the site, particularly since I’ve been talking about ketosis so much recently (both on ClimbSci with Tom and then in a subsequent article). At any rate, it gives me another opportunity […]
Read the full article...Random End-of-Year Updates
We’re nearing the end of the year, and what a year it’s been. I’ve been absent in the past few months compared to my usual schedule, only putting out a few articles and some episodes of ClimbSci. I owe you, my reader, an explanation for that. Those of you who follow this site probably know […]
