The AMA and Creatine
/in Memos/by Chet ZelaskoAfter 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
/in Memos/by Chet ZelaskoI 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
/in Memos/by Chet ZelaskoI’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 […]
Adaptation: Maintenance
/in Memos/by Chet ZelaskoWhile 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
/in Memos/by Chet ZelaskoAs 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 […]
Adaptation: Exercise
/in Memos/by Chet ZelaskoI 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 […]
Adaptation: Recovery
/in Memos/by Chet ZelaskoIn 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: […]
Obesity: A Man-Made Disease
/in Memos/by Chet ZelaskoIn order to determine whether obesity is an untreatable disease without pharmaceuticals, I took a look at BMI data since 1960. In comparing the BMI of people in the lowest income brackets with the highest income from 1960 through 2024, the lowest income group is always about one BMI unit above the highest income group. […]
Is Obesity a Disease?
/in Memos/by Chet ZelaskoIn a podcast about GLP-1 receptor agonists and several new medications that are under development, the expert was a researcher on the cutting edge of what these peptides can do for weight loss. A couple of things she said didn’t sit right. One was that obesity is a disease of genetic tendencies to store fat […]
Absolutely Monumentous!
/in Memos/by Chet ZelaskoHappy Mother’s Day to all the mothers who perform monumentous tasks every day. For those of you who still have your mom in your life, make it a habit to treat your mom like every day is Mother’s Day. It’s similar to working on your health. It’s not what you do once in a while […]
