Paleolithic Diet: More Hype than Hope?

August 11, 2026/in Memos/by Chet Zelasko

Over 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

August 8, 2026/in Memos/by Chet Zelasko

Here 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 […]

Election Day: Get Wild!

August 4, 2026/in Memos/by Chet Zelasko

Today from coast to coast, there are primary elections being held—five today, including Michigan, and about a dozen more the rest of the month. It’s not just the U.S.—it looks like Iceland, Kosovo, U.K., and Zambia have elections this month, and there may be more I’ve missed. I’m a Michigan election inspector and will be […]

Use Animal Protein to Build Muscle

August 1, 2026/in Memos/by Chet Zelasko

Plant-based food versus supplemental shake: that is the question. It’s not the only question, but it’s where we start today’s Health Memo. The supplemental shake used in the study used the same type and amount of amino acids found in the rice and beans. They also used the same amount of carbohydrates, fiber, and fat. […]

Plant-Based Protein: Food vs. Shake

July 28, 2026/in Memos/by Chet Zelasko

There are many questions related to every aspect of nutrition. Most may seem trivial, but it doesn’t mean it won’t be helpful to know the answers. One that’s important to protein synthesis is whether a person can get enough protein from complementary plant foods or plant-based protein from shakes with the same nutrient distribution as […]

HIIT Can Be Fun

July 25, 2026/in Memos/by Chet Zelasko

After you’ve checked with your doctor to find out any limitations as it relates to exercise intensity, then it’s time to get after it—not to lose a whole bunch of weight, not to win the next 5k, not every day—but to make your heart and body stronger and fitter. Modes of Exercise for HIIT The […]

HIIT Fun?

July 21, 2026/in Memos/by Chet Zelasko

I have a confession: I married a woman who doesn’t like to exercise. I know—it’s not what you’d expect from guy committed to a career in making people fitter and healthier, but she was and is irresistible. Since we met, I’ve been on the lookout for fun ways to exercise, especially since HIIT (high-intensity interval […]

HIIT for Everyone

July 18, 2026/in Memos/by Chet Zelasko

Before I get into this study on high-intensity interval training or HIIT, I want to be sure you understand that unless you’re under 30 and very fit, you need guidance and advice from your physician before you attempt a HIIT program, especially if you have cardiovascular disease, diabetes, or are on medications for these conditions.

HIIT at Any Age

July 14, 2026/in Memos/by Chet Zelasko

Last week, I talked about taking inventory of where your body is now, primarily in your ability to move your limbs. The reason was that regardless of age as well as physical limitations, you can improve your fitness level; better yet, you can potentially accelerate the process using high-intensity interval training, also known as HIIT.

To make this easier, we created a printable checklist that you’ll find in the Basic Health Info section of drchet.com. Physical Inventory Let’s start with some of the factors […]
