Intermittent Fasting

A colleague of mine had suggested/introduced “The Obesity Code” to me and my reading list.  It’s a fabulous read and I highly encourage a read/listen.  Here are other books I have read and suggest.  After The Obesity Code, I chose The Complete Guide to Fasting… and since then, I’ve added Eat Stop Eat to my audiobook library as well.  I’m extremely intrigued about intermittent fasting.  I’ve followed a paleo diet for years, however, I’m curious to see if I could actually try intermittent fasting and not succumb to hunger bc I love snacking!

Here are some resources I’ve found to be useful:

From Brad Pilon, author of Eat Stop Eat:

To summarize: a rather normal dose of alcohol caused a decrease in fat burning, no change in carbohydrate burning, and a slight increase in overall calorie burning in men who were in the fasted state.

So the question remains. If metabolic rate increases, glucose oxidation stayed the same, and fat burning decreased… what the heck were they burning?

Turns out the answer is the alcohol… sort of.

In fact, blood acetate is such a priority that it’s mere presence can decrease lipolysis by ~50%, even when you are in the fasted state [Crouse JR, 1968]

And this is what happens when you drink during your fast. It’s not that you will gain more fat (unless you are drinking excessively), but you will stop releasing body fat, stop burning body fat, and burn acetate instead. This occurs without any change in insulin levels.

So sadly, it seems the answer is that you cannot drink during your fasts without diminishing your fat burning abilities.

 

I’ve decided to try the 16/8 IF schedule (16 hour fast, 8 hour eating window = 11a – 7p) when I go back to work.
