Answering this research question

Reading this summary, I felt an urge to blurt out: "No blank, Sherlock!"

A recent study published in JAMA, a leading pillar of medical research dissemination, compared low GI diets with low-fat diets on insulin secretion in high insulin secreters.

On the surface, this appears to be a legitimate research question. Insulin is related to glucose metabolism and given the current state of obesity and type II diabetes in America, this might be something we should know.

However, most people in the medical fields should intuitively know this. The glycemic index of any food indicates the level it raises blood sugar when consumed. The higher the glycemic index, the higher the blood sugar response. For example, twinkies rate rather high on the glycemic index. Consume two or three of them and your blood sugar will spike.

At least for a while. In response, your body will release (secrete) insulin to bring it back down to normal.

If you are a high insulin secreter, you're either type II diabetic, pre-diabetic or have a non-lifestyle related condition effecting your ability to metabolize blood sugar. You have to secrete more because the insulin you do release is becoming more and more insensitive to blood sugar. When this starts happening, the amount you secrete increases just to get your blood sugar back to normal. Over time your ability to regulate blood sugar becomes difficult and you become type II diabetic. For more info, go here.

But back to the study...

All markers of cardiovascular health were improved following low GI diet when compared to a low-fat diet. Again, this makes perfect sense. You're not obese or diabetic because you eat a low-fat diet of whole, natural foods. You're obese or diabetic (even if you eat a low-fat diet) because you are consuming overly-processed foods - cardboard boxes and plastics bags. The fat they contain is not healthy (trans fat) and to increase palatability (here) and shelf-life, sugars and preservatives are added.

The end result is a low-fat food that has a high GI, which increases insulin secretion when consumed. And the cycle continues...

I'll conclude by saying that as a former academic, I'm well aware the importance peer-reviewed publications play in the tenure process. So in some ways, I understand why this paper was published. Without knowing all the details, I can only hope this paper was part of a larger study with these data points already collected, making the question easy to answer.

Until next time...

Training online!

On Monday, May 21, 2007, we'll debut the beta version of our online Golf-Fitness Boot Camp. For several reasons, this is great news for you!

First, even though it's the beta version, all features of the full-blown online Golf-Fitness Boot Camp will be fully tested and in working order before we complete beta testing. If you ever considered improving your golf game through a fitness program, this is your best opportunity to do so.

Why? Because while in beta test mode, the online Golf Fitness Boot Camp will be absolutely FREE! All you will have to do is register and we'll take care of the rest. To stay abreast of the updates, sign up for Brian's Report.

Second, you can't get a workout like this anywhere else - all for FREE! So sign-up for the trial period and use it to your advantage.

Third, by the time beta testing is complete, you'll be able to hit the ground running with your workouts. In other words, the learning curve associated with getting started won't eat into your monthly (or annual) payment.

That's it. Those are three good reasons to get started. Now, sign-up for Brian's Report and don't miss this opportunity!

Finally back to posting!

It's good to be back!

I know, it's been a while but I have a good excuse - I bought a fitness center.


Unfortunately, that kept me from finishing my journey. But in case you were wondering, I've fully recovered and have no ill effects! Now, if I could just find the time to get out on the course.

I'm still deciding on how to best utilize my blog. There certainly will be fitness center updates, videos of workouts and camps and more. You can subscribe to the feed for updates - just use the Atom Syndication below and to your right. Alternatively, you can sign up for Brian's Report, my golf-fitness newsetter.

One idea I've been thinking about are health related posts. I subscribe to several medical news alert services. Nearly everyday I see a headline that makes me scratch my head or simply say "Duh!" I'm thinking about publishing these to the blog 3-4 times per week. Hopefully it will be entertaining and educational for you.

What do you think?

Any ideas?
