Interesting, and you know, really, that's a no-brainer, when you think about it. I don't understand why the researchers/author say this:
There's nothing mysterious about the process. The body is an engine - a prime mover. The primary fuel is glucose, but similar to a multi-fuel truck engine, it will run on an alternate fuel, namely fat. The only time that the alternate fuel option is invoked, though, is when energy is expended, while blood glucose is in short supply, thus forcing the burning of stored fat.
The problem with this exercise routine, (as the article points out), is that it is good for losing weight, but worthless for improving muscle tone, endurance, etc. Just the thought of having to get up a couple of hours earlier, to torture oneself this way, would seem to provide enough inspiration to put a damper on the overindulgence planned for later in the day. I realize a lot of people do this, but, is it worth it?
I agree, that's an interesting article. Thanks for posting the link.

Why do they think fasting blood tests are done before breakfast? Because blood sugar is at a minimum point in the cycle, before breakfast. Therefore, if any vigorous exercise is done in that condition, most of the fuel, (after a certain amount of time), will have to come from stored fat, (since the blood sugar will be relatively quickly depleted). This procedure doesn't "coax" the body to burn a greater percentage of fat - it forces the body to burn fat. IOW, contrary to what the article says, this routine doesn't "prevent" the body from storing fat in muscles, rather, it burns fat that was previously stored in muscles, (which will presumably be quickly replaced by overindulgence later in the day).Just how exercising before breakfast blunts the deleterious effects of overindulging is not completely understood, although this study points toward several intriguing explanations. For one, as has been known for some time, exercising in a fasted state (usually possible only before breakfast), coaxes the body to burn a greater percentage of fat for fuel during vigorous exercise, instead of relying primarily on carbohydrates. When you burn fat, you obviously don’t store it in your muscles.

It is suspected that some of the hardest material known to science can be found in the skulls of GI specialists who insist that diet has nothing to do with the treatment of microscopic colitis.
