Our Guts, Our Selves

Published by

When people talk about “gut feelings”- something they can’t really rationalize, but feel as though the emotion is “coming from the heart” or “I feel it in my guts”, are those feelings actually coming from the heart or gut? Well no. But this doesn’t mean that the heart and gut do not influence our moods, decisions, and behavior. They do, especially the gut. How could the gut possibly influence our minds, and why? First let’s address the question of why. Although we often tend to treat our bodies as just something to walk our minds around, our bodies are important parts of who we are (for an account of what it is like to lose a sense of your body, see “The Disembodied Lady”, by Oliver Sacks, in The Man Who Mistook His Wife For A Hat). But the gut is special! That is, if you are any kind of a complex animal, you have to have one. Even tardigrades, the super tough little animals that can survive extreme conditions, like being frozen to -300 …

Why I Love Greek Yogurt

Just a few years ago, probiotics were considered to be an “alternative” thing that only hippies were into. Most “probiotics” were pills with only one or two bacterial species, and there was little concern about quality control. Most medical practitioners considered probiotics to be a rip-off, or a fad. And there was no evidence that probiotic bacteria can even live or form colonies in our guts, so it was assumed that they could not affect our health.   My how things have changed.   Technological advances, thanks to the Human Genome Project, have given us a much better idea of the microbes in our guts. Instead of relying on culture techniques (trying to take bacteria from our guts and grow them on an agar plate or in a tube- which they don’t like, because they only like to grow in our guts), we can now identify them using DNA/RNA sequencing of their genes. And wow! We discovered that thousands of different kinds of bacteria live in our guts, and some of them are the same …

Mindful Eating, Or- How I lost 35 pounds by enjoying my food more

Like many people, I found myself overweight in middle age. Quite overweight, in fact. With a BMI (Body Mass Index) of 30, I was more than overweight. My fasting blood glucose levels were still in the normal range, barely. My mother continued to remind that I have Type 2 diabetes in my family. What to do? As a scientist who has studied obesity and body weight regulation, I knew that dieting was not an option. The starvation response/ diet induced obesity, and all that. So… I decided to take my own advice. Background: There are two kinds of things that influence how much we eat: “Head Factors” and “Gut Factors”. Head Factors are “psychological” things such as how appetizing the food looks and smells. Social cues or influences, emotional situations, habits and conditioning (e.g. always eating a snack at 4 PM) are also powerful influences on what and when we eat. Gut Factors are signals from the gut (and/or liver) that convey the gut’s opinion about how much we should eat, and may also influence …

Is “Leaky Gut” Really A Thing?

Published by

There is no shortage of information on the internet about “Leaky Gut” and “Leaky Gut Syndrome”. For instance:   “4 steps to heal Leaky Gut” “9 signs you have a leaky gut” “Leaky Gut foods to avoid” “Could Leaky Gut be what is troubling you?” “Leaky Gut: Can this be destroying your health? “How to live with and identify Leaky Gut Syndrome” Is this really a thing? It seems there are as many skeptics about “Leaky Gut” as there are people promoting it. When I ask audiences at my seminars “Who has heard of leaky gut syndrome?”, everyone, EVERYONE, raises their hand. When I ask “Who thinks the medical establishment takes it seriously?”, no one raises their hand, ever. Which is unfortunate, because Leaky Gut is a thing, and can cause serious problems for some people. It may also contribute to other conditions not normally thought of as being related to gut problems. In the basic science world, “leaky gut” is called “increased intestinal permeability”, and it is a big thing. Increased intestinal permeability is …
