#2 – Deep Dive Into Glut Subtypes and Exercise

Glucose transporters (aka Glut) are a key protein that shuttles glucose into cells.  Understanding Glut helps you understand how your body transports and utilizes sugar, and how you can impact your glucose metabolism through lifestyle changes like exercise.  We'll use some clever mnemonics to…


#1 – Using Mangos to Explain Insulin and Glut4

This is the first of a series of episodes that digs deep into insulin's actions and uses what I call the "mango cell model" so you understand the key components of cell structure.  I'm also going to introduce a key glucose transporter called GLUT and end with my opinion about mangos and fruits…


#3 – Beta Cell Batteries, Fasting, and Ketosis

Beta cells are the insulin-producing cells in our pancreas and their durability is a key factor in promoting longevity and optimal health.  In this episode I use the battery analogy to explain how beta cells work and what actions you can take to preserve your beta cell battery life which helps…


Is It Time to Rethink Omega-3 Supplements?

Background I received lots of questions about recent headlines reporting an increased risk of atrial fibrillation in individuals taking omega-3 supplements.  In the US alone, over $1.2 billion dollars is spent on the consumption of fish oil supplements.  On an individual basis, many of my patients…


The Glycemic Impact of Stress

Background Many of you have probably read or heard about the impact of stress on glucose.  Despite this, most people are only partially convinced about the connection.  Unlike the impact of something concrete and tangible like food and physical exercise, it's often difficult to accept that…


Insulin Training and Glucose Variability

Background I know in prior writings I mentioned how I've been tracking my health less and living more spontaneously by intuition.  Wearing trackers and doing frequent blood tests for over a decade has given me a strong sense of when my metabolism and energy are off, so now I just mostly pay…


The Fallacy of Fasting Blood Glucose

Background If there is one "abnormal" blood test that I get the most questions on, it has to be the fasting blood glucose.  As a result of implementing stringent lifestyle changes, often patients see their waistlines shrink, their lipids improve, but that stubborn fasting blood glucose often…


Is Intermittent Fasting Overrated and Harmful to Health?

Background I got a ton of questions from patients and readers about the recent UCSF study on a form of fasting called time-restricted feeding (TRF), being ineffective for weight loss.  This is a perfect opportunity for me to dig deeper into how fasting can either be a powerful tool that potentially…


VO2 Max and Other Key Markers of Fitness and Longevity

Background There is no doubt that improving diet is a powerful way to shift metabolism and reverse conditions like insulin resistance and chronic inflammation.  In fact, in my early days, simply changing the diet in patients led to such significant changes in metrics like body weight, triglycerides…


The Continuous Glucose Monitor (CGM) Guide

Background A continuous glucose monitor (cgm) is a wearable sensor that tracks you blood glucose 24/7 in real time and transmits it to a receiver which can either be a separate unit or your smartphone.  It's time for doctors and practitioners to get comfortable ordering cgms for their patients.  We…
