Last year, I wrote a post about why I chose the Aquacera Countertop SS as my water filter. In that post, I told the story of how I almost bought a Berkey but went with the Aquacera because of its smaller size. In this post, I describe why I’ve now switched to the Berkey. Here’s …
This lesson covers the regulation of glycolysis. The principle regulation occurs at phosphofructokinase, which guards the gate to the first irreversible, committed step to burn glucose for energy. What governs it? Energy. If you need more ATP, you burn more glucose; if you don’t, you don’t. If the cell has glucose beyond its needs for …

Our consciousness is like a net. We want the net to be fluid enough to let thoughts that bother us pass through without grabbing our attention, but strong enough to grab on to the ideas and motivations that will drive us to achieve what we value in life. Nutrition has a big impact on this …
In this lesson, we examine beta-oxidation in its simplest form: the breakdown of a long-chain, saturated fatty acid. We see once again the principle that the oxygen content of a molecule determines how much water its metabolism consumes and how much carbon dioxide its metabolism releases. In beta-oxidation, we consume one water per round and …
In this lesson, we examine the entire glycolytic pathway. We use as our theme the transfer of oxygen from phosphate to newly generated water. This explains why the standard stoichiometry of glycolysis found in textbooks show it generating two water molecules, and ties the information together with the analogous principles from substrate-level phosphorylation in the …
In this episode, we look at whether fat can fuel the athlete. We begin with the physiological principles involved, then take a look at the evidence from studies swapping fat for carbs to see how it impacts athletic performance. Listen on ITunes or Stitcher.
