Carbohydrates and Insulin
/in Memos/by Chet ZelaskoOn a typical busy morning, a person has a fairly good dose of carbohydrates in the form of a sugary cereal, a bagel, a pastry, or a breakfast sandwich from a drive-thru. Then a couple of hours later, they seem to crash—not their car, but their energy seems to drain away. Maybe they start to […]
Three Challenges
/in Memos/by Chet ZelaskoThis weekend is the last holiday of the summer or the first of the fall, depending on how you look at it. I’d like to challenge you to try three different tasks if they are not part of your regular routine. I’ve talked about high-intensity interval workouts a lot the past couple of months. I’m […]
Functional Essential Fatty Acids
/in Memos/by Chet ZelaskoUnderstanding that linoleic acid is the essential omega-6 fatty acid and alpha-linolenic acid (ALA) is the essential omega-3 fatty acid, the logical question would be what about fish oil and other sources of omega-3 fatty acids? It’s just a little complicated, but let me explain. It’s true that in humans, we can use ALA to […]
Essential Fatty Acids
/in Memos/by Chet ZelaskoThere are always controversies in nutrition. With all that’s been written about seed oils and sources of omega-3 fatty acids, I thought we’d go back to the basics this week—back to what are the essential fatty acids, seen above floating in the bloodstream.

/in Memos/by Chet ZelaskoThe top sumo wrestlers weigh an average of 355 pounds. I watched a little wrestling when Konishiki, a Hawaiian sumo, was popular; he had been the heaviest sumo up to that time weighing over 600 pounds. The question is with weighing so much, are sumo wrestlers at risk for weight-related disease? It comes down to […]
Body Fat: Location Matters
/in Memos/by Chet ZelaskoLast week, I mentioned in passing that a hippopotamus has less body fat than most humans. Since then, I’ve wondered exactly how little body fat they had. By several estimations, it’s around 5%—about the same as elite soccer players. That’s not enough fat to cause the hippo health problems as we see in humans; they […]

I checked out Dr. Daniel Lieberman’s research, and he is a leading expert in his field. There are three facts that stood out to me. Three Facts The first thing I learned is that hippopotami have […]

Paleolithic Diet: More Hype than Hope?
/in Memos/by Chet ZelaskoOver the weekend, I was listening to a podcast about the Paleolithic diet. Daniel Lieberman, the expert being interviewed, has focused his research on the Paleolithic era. I found it quite interesting based on the number of gurus and influencers that continue to say that era was the diet we should mimic for optimal health. […]
Exercise on the Wild Side
/in Memos/by Chet ZelaskoHere are a few observations and comments about exercising on the wild side. What we think about structure and uniformity to our schedule is important; having a schedule and sticking to it relieves you of the need to decide what you’re going to do every day. But some of the time, we just have to […]
