The People's Scientist

In episode 148, I go through the details of two recent studies investigating the impact of fasting on hunger and craving circuits within the brain. After one bout of fasting, persistent amplification of excitatory activity was noted onto agouti-related protein neurons of the arcuate nucleus of the hypothalamus. I believe these studies provide an understanding as to why we may binge and re-gain weight after weight loss. Can we use this information to our advantage? Yes. I give some neuroscience based strategies to help us prevent weight re-gain. Tune in for details.

Today in Episode 147, I have the great joy of interviewing Naval Officer, LTJG Joseph Gills, who led his team to achieving the award Thor's Hammer by obtaining the top scores in the Pacific Fleet competition of 2022. LTJG Gills goes through personal examples and suggestions to achieve good leadership and how to work with bad leadership. For example, he mentions how being a leader is a gift, an opportunity to serve people, not an opportunity for personal glory. If we can lead a great team, the personal accolades with follow. Tune in for more details!

In Episode 146 I share some recent scientific evidence on the Neuroscience of Itch. We have yet to fully grasp this relatively new area of science but we appreciate that sensory fibers in the skin send signals along our spinal cord to the thalamus of our brain. But did you know that scratching can be contagious? If we see someone scratch, we may feel inclined to unconsciously scratch as well. This is related to mirror neurons. I get into the neuroscience behind different types of itch, the causes, and how we understand the science behind itch today. Tune in for details!

In episode 145 I share some scientific evidence on intestinal barrier dysfunction AKA: leaky gut. I use analogies to explain what leaky gut is, how this can contribute to brain inflammation, dementia, major depressive disorder, and scientific evidence on how to promote the health of our intestines and brain.

Episode 144 is a special episode as a recent conversation with my sister sparked this topic! My sister and I were talking about how the attitude toward food has changed drastically over the last several decades. We talk about our personal experiences in the context of diets, how hormones may be involved, intuitive eating, how nutrition clinical trials should focus on mental health and efficacy, and how the condition of bulimia nervosa may be far more prevalent than what we realize. Tune in for all the details.

In episode 143, I continue with the theme of love for February but approach it from the opposite direction and share the Neuroscience of Heartbreak. Heartbreak is an intense emotional pain arising from the loss of a valuable relationship. In this episode I share Neuroimaging studies that indicate emotional pain recruits the same brain regions as physical pain. How scientists speculate that chronic pain disorders may actually arise from chronic emotional pain. I also talk about broken heart syndrome called takotsubo cardiomyopathy. I discuss some suggestions on how to reduce emotional pain using this neurobiological understanding. Tune in for all the details!

In Episode 142, I share some neuroscience on trust and vulnerability. To trust, we make ourselves vulnerable by relying on another individual to fulfill their role. The main reason why employees leave their job and why marriages end in divorce is because of a lack of trust, communication and appreciation. So clearly, trust is central to the success of strong relationships. In this episode I give several practical strategies on how to build trust and being aware that small things may chip away and weaken the trust in a relationship. Tune in for details!

In Episode 141 of The People's Scientist podcast, I propose a theory; are we addicted to our rises in blood insulin? Back in the 1940s, injections of insulin were given to treat anxiety and neurosis. They noted that injections of insulin induced a calming effect, sedation, and enhanced motivation to obtain food. In more recent studies we see that insulin may act on brain reward regions. Higher insulin responses after eating leaves one feeling less satisfied and craving more food. I go into some evidenced based strategies on how we may be able to influence our insulin levels and therefore perhaps our food cravings. As always, please seek the advice of your physician or dietitian. Tune in for the interesting details!

At many points in our life, we are likely to need to start over; in relationships, careers, school, etc. Here in Episode 140 of The People's Scientist podcast, I share clinical studies that provide some insight on how we can enhance our success in starting over. I highlight three key components: 1) Overcoming our fear of rejection/failure 2) Increasing self-confidence 3) Creating goals and instilling new habits. Tune in for all of the scientific details.
