UV-Rays

Protect Your Skin

June 20, 2026/in Memos/by Chet Zelasko

Astronomical summer begins tomorrow morning at 4:24 a.m. EDT in the Northern Hemisphere, the point when the earth will be closest to the sun. Because it will also be the longest day of the year, it will also provide the greatest exposure to the sun and its ultraviolet light if you’re going to be outdoors. […]

BEMT-Sunscreen

New Sunscreen Ingredient

June 16, 2026/in Memos/by Chet Zelasko

Bis-ethylhexyloxyphenol methoxyphenyl triazine! Say that five times fast. Heck, say it fast once! No, this isn’t a memo about tongue twisters; it’s about the FDA finally approving a new ingredient for sunscreen in the U.S. A simpler name is BEMT, bemotrizinol, or Tinosorb-S. Why a new sunscreen ingredient? It not only neutralizes the free radical […]

Creatine and the Unasked Question

June 13, 2026/in Memos/by Chet Zelasko

If you read the article on creatine posted by the AMA, while as short as a sentence or two, the points were valid. Let me elaborate on a couple of the ones I think are most important. Creatine Builds More than Muscle The point they were making is that creatine may be beneficial to build […]

The AMA and Creatine

June 9, 2026/in Memos/by Chet Zelasko

After last week, you may be thinking I’m going to talk about another healthcare professional dissing supplements. I’m very pleased to say that’s not correct this time around. You can read the article by clicking here; I wouldn’t recommend listening to the audio version—seems like an AI voice to me. The first thing that blew […]

Questionable Comments on Dietary Supplements

June 6, 2026/in Memos/by Chet Zelasko

I hope you had a chance to read the article I referred you to on Tuesday; you can still read it by clicking on this link. For the record, I’m not a fan of the AG1 product. In my opinion, supplements should not mix herbals from medicinal plants with vitamins, minerals, and phytochemicals. That aside, […]

Let’s Talk About Dietary Supplements

June 2, 2026/in Memos/by Chet Zelasko

I’m in a constant state of frustration over comments about the use of dietary supplements. Not by gurus and influencers; I don’t expect much from them except promotion of specific products for monetary gain. I mean the people with the credentials, with the scientific background, who say things that are simply not accurate. They seem […]

Maintenance

Adaptation: Maintenance

May 30, 2026/in Memos/by Chet Zelasko

While you’re losing weight, I’ve always taught people to adopt a diet you can maintain for the rest of your life, because that’s how you’re going to have to eat for the rest of your life to maintain your weight loss. During the process, you have an opportunity: it’s going to take time to lose […]

Adaptation: Weight Loss

May 26, 2026/in Memos/by Chet Zelasko

As I said when I began this arc, the key point is that whether intentional or as the result of challenges such as joint replacement, the body’s adaptation to repair and growth takes time. This week, I’m going to look at adaptation related to weight loss and weight maintenance. No matter how we choose to […]

Walking

Adaptation: Exercise

May 22, 2026/in Memos/by Chet Zelasko

I can’t think of a better example of positive adaptation than exercise. Whether it’s a sport skill, increasing strength, or improving cardiovascular fitness, exercise uses the adaptation principles; the difference is that it’s an intentional act instead of a response to a physical challenge. As an example, let’s use walking or running to improve the […]

Recovery

Adaptation: Recovery

May 19, 2026/in Memos/by Chet Zelasko

In this Memo arc, I’m going to lay the foundation to support my opinion that obesity is a man-made disease. I’m adding this idea to that opinion: reducing body weight and maintaining the weight loss can occur with man-made solutions. Actually, it’s utilizing one mechanism we often overlook that the body uses all the time: […]
