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

Burning Body Fat With Cold Exposure

Background I have many patients who get the impression that staying healthy is not a year round responsibility.  They tend to focus on physical activity and healthy eating when the weather warms up, but during the fall and winter months, they think they can magically transform into a hibernating…


Case Files: Elevated LDL Fixed

Background I'll be sharing some occasional cases from my clinic to help you learn about some of my approaches to helping my patients.  I'll make some minor changes to the history and possibly tweak the labs a bit to protect the patient's identity.  My goal for doing these case files is so my…
