Cognitive dissonance is a psychological phenomenon that occurs when a person holds two contradictory beliefs at the same time. The psychologist Leon Festinger came up with the concept in 1957. Festinger believed that all people are motivated to avoid or resolve cognitive dissonance due to the discomfort it causes, and it can prompt people to adopt certain defense mechanisms when they have to confront it—namely, avoidance, delegitimizing, and limiting the impact. The last thing people seem to want to do is confront the conflicting ideas and change their beliefs. Sadly, scientists are not immune to this phenomenon. Today I am going to present some recent studies that are generating cognitive dissonance even though they do a better job of explaining phenomena related to cholesterol levels than the traditional theories.
Read MoreOn January 17, 2024, a groundbreaking study titled "Increased Low-Density Lipoprotein Cholesterol on a Low-Carbohydrate Diet in Adults with Normal but Not High Body Weight: A Meta-Analysis" was published by Adrian Soto-Mota, Dave Feldman, Nicholas Norwitz, and others. This research provides new insights into the effects of low-carbohydrate diets on cholesterol levels, with a particular focus on low-density lipoprotein cholesterol (LDL-C), commonly known as 'bad' cholesterol. In this blog post, I will explain the study's design and results, which refute the current medical thinking that saturated fat has the most significant effect on raising cholesterol. The authors found that body weight is much more significant than saturated fat. Their findings suggest that we have things backward.
Read MoreA famous paper from 1970 enticed children with a marshmallow and told them they would get an extra one if they waited for their treat. This study did not track the children into adulthood. Later on, the data was reviewed by additional researchers who contacted the children to see how they fared in life. They determined that the kids who waited longer were the more successful ones. Another study was done more recently that debunks the idea that willpower equates to success. I will decipher what is happening in this post and try to get to the the truth.
Read MoreAfter repeated conversations with me, a close relative in his late 50s decided to try the carnivore diet. He immediately began to feel better than he had ever felt. The carnivore diet is ultra-low-carb, similar to the ketogenic diet, which often raises LDL and total cholesterol. He has lost 22 pounds, lowered his BMI from 25.8 (overweight) to 22.8 (normal), lowered his blood pressure from 110/70 to 100/66, has more energy, lowered his triglycerides from 106 to 71 (lower is better), raised his HDL from 47 to 79 (higher is better), lowered his VLDL by 1/3, rid himself of chronic foot and hip pain, and he has no more leg cramping. As we will see later in this post, these changes indicate inflammatory, metabolic, and cardiovascular health improvements.
At the same time, he raised his LDL from 69 to 192 and his total cholesterol from 137 to 285, which made his doctors panic. Later in this post, we will see that LDL levels below 105 cause twice the amount of death. Despite this, his doctors have ignored nine positive changes and stressed two that, as we will see in this post, have little relevance in their ability to predict cardiovascular disease. What kind of a world do we live in when doctors fret when their patients become healthier? Read on if you are curious.
Read MoreA recent study found that lean people's brains respond to nutrients differently than obese people. Specifically, the obese people's brains did not respond as quickly to the presence of nutrients. Sadly, when the obese people lost weight as part of the study, their brains still did not recognize they had eaten as quickly as the lean group, explaining why diets only result in temporary weight loss. I will go over the particulars of the study in this post and what it might mean in practical terms.
Read MoreA few years back, I wrote about the negative health consequences of visceral fat, which is the kind of fat that surrounds our organs. Too much of it is bad for our health. I spoke about several ways to measure it, but I want to concentrate on one very easy and free method called the waist-to-height ratio. It is a simple and free method you can do at home to determine your health risk. I will tell you why it is so important and tell you how to calculate yours. For the math-challenged, I have a link to an automatic calculator.
Read MoreWhy are so many Americans overweight or obese? Are we weak? Are we addicted to unhealthy foods? The answer is probably not. I took a look at how our food supply has changed over the years, and it may explain our ever-expanding waistlines. This post will cover the trends, investigate some of the science, and, finally, talk about what we can do to lose weight and become healthier.
Read MoreThe combination of obesity, specific heart-health markers, and some metabolic measurements are collectively known as metabolic syndrome. Essentially our metabolism has a direct impact on our overall health and heart health specifically. The health implications are dire, not just for our cardiovascular systems. With Covid-19, obesity is strongly associated with increased severity of COVID-19 infections, even in the absence of other underlying health issues. In this post, I have included an interactive guide to all of the steps you need to include to improve your looks, mood, and energy level. Your "body composition" will take care of itself as you focus on the things listed in the guide. Best of all, your chances of dying from disease and infection will diminish.
Read MoreCombined with age and neck circumference, a Mallampati Score over 2 is about 94% predictive of sleep apnea. When I see a Mallampati score of 3 or 4, I know the airway is compromised and dig a little deeper into the patients’ backgrounds. If you have never heard of the Mallampati classification system, you are in the majority. It is actually something you can measure yourself. Read on if you are curious.
