Why hemoglobin A1c is not a reliable marker

By on March 1, 2011 in Lab testing | 50 comments

Over the last few years doctors are increasingly relying on a test called hemoglobin A1c to screen for insulin resistance and diabetes. It's more practical (and significantly cheaper) than post-meal glucose testing, and it's less likely to be skewed by day-to-day changes than fasting blood glucose. What is hemoglobin A1c? Sugar has a tendency to stick to stuff. Anyone that has cooked with sugar can tell you that. In our bodies, sugar also sticks - ...

Grass-fed vs. Conventional Meat: It’s Not Black or White

By on January 4, 2011 in Food & Nutrition, Paleo Diet, Stress | 25 comments

I hope you all had happy holidays and are off to a great start this year. I thought I'd share a few thoughts that have been bouncing around my head lately, stimulated most recently by two articles written by fellow health bloggers. Don Matesz over at Primal Wisdom wrote a thought-provoking piece on the hormone composition of grass-fed and factory-farmed meat. In it he argues (convincingly, I might add) that meat from CAFO (confined animal feeding operations) ...

Why your “normal” blood sugar isn’t normal (Part 2)

By on November 18, 2010 in Diabesity | 278 comments

In the last article I explained the three primary markers we use to track blood sugar: fasting blood glucose (FBG), oral glucose tolerance test (OGTT) and hemoglobin A1c (A1c). We also looked at what the medical establishment considers as "normal" for these markers. The table below summarizes those values. Marker Normal Pre-diabetes Diabetes Fasting blood glucose (mg/dL) <99 100-125 >126 OGGT / post-meal (mg/dL after 2 hours) <140 140-199 >200 Hemoglobin A1c (%) <6 6-6.4 >6.4   In this article, we're going to look at just how "normal" those normal levels are - according ...

Intermittent fasting, cortisol and blood sugar

By on November 17, 2010 in Paleo Diet, Stress | 28 comments

There's been a lot of discussion about the benefits of intermittent fasting (IF) in the paleo community lately. Paul Jaminet mentions it's role in boosting the immune system in his book, The Perfect Health Diet, and IF can also be helpful for those trying to lose weight and tune their metabolism. From an evolutionary perspective, intermittent fasting was probably the normal state of affairs. There were no grocery stores, restaurants or convenience stores, and food ...
