Analysis of my new lipid panel

Posted in Preventive Medicine, Transformation on February 29, 2008 by Dr. CJ

The results are in. I have to admit, I expected better numbers compared to my lipids measured 1.5 years ago, but here goes:

– – – – – – – – – – – – – – – – – – – – 5/2006 – – – – – – 2/2008

  • Total Cholesterol – – – 197 – – [<200] – – – – – 191
  • HDL-C – – – – – – – – – – – 34 – – [>39] – – – – – – 36
  • LDL-C (calculated) – – 140 – – [<130] – – – – – 146
  • Triglycerides – – – – – – 113 – – [<150] – – – – – 44
  • TC/HDL ratio – – – – – – 5.8 – – [<5.0] – – – – – – 5.3
  • Fasting glucose – – – – – 71 – -[<100] – – – – – – 78

My observations:

  1. HDL is slightly higher, not to goal.
  2. LDL slightly higher (OUCH . . . really can’t explain this one).
  3. Triglycerides are considerably lower – I don’t know if I’ve ever seen one this low. At least one portion of my lipid panel changed considerably – too bad it was already normal.
  4. TC/HDL ratio is slightly improved, but still not to goal.

I have a couple theories to explain the less-than-stellar improvements in these numbers.

  1. Family history – there is definitely a history of low HDL/high LDL on my maternal side.
  2. Labs were performed at different labs – hard to estimate the impact of this one, but certainly can be a factor.
  3. Last year, I really only stuck to my solid regimen for 4 months. After that, I had a tremendously busy, stressful year that precluded a good fitness routine. Thus, these numbers probably reflect only a solid 6-7 weeks of my regimen from this year, following a 7-8 month period of relative inactivity prior to that.
  4. I discovered a study that demonstrated the HDL responding less to exercise in individuals with low Triglycerides compared to individuals with high Triglycerides. This article highlights a possible explanation for why the HDL did not increase as much as I expected. This finding is news to me – never heard/read about this concept before.
  5. Last year, I was taking a protein supplement that had quite a bit of fat, including saturated fat. That may have accounted for the higher LDL. I’m currently using a pure protein supplement with no fat. That’s the only supplement I will use. [That’s a topic for another day.]
  6. HDL probably increases better as a result of longer-duration endurance training workouts than I get with High-Intensity Interval Training (HIIT) workouts on the elliptical. Could this be one limitation of HIIT?

Regardless, this just serves as another motivator for me to turn everything up a notch. I’m not a fan of long-duration endurance training, but I will probably incorporate more into my training. At least in the summer, I will do a large amount of biking.

I’ll be checking these numbers again in a year. I refuse to depend on medication, so I’ll be working hard.

My old lipid panel – pre-transformation

Posted in Preventive Medicine, Transformation with tags , on February 28, 2008 by Dr. CJ

Back in May, 2006, I last had some blood work done, for an insurance exam, that included a lipid panel. I, of course, held onto those results, because I obsess over my risk factors for heart disease. Here they are, in their unimpressive glory.

  • Total Cholesterol – – – 197 [<200]
  • HDL-C – – – – – – – – – – – 34 [>39]
  • LDL-C (calculated) – – 140 [<130]
  • Triglycerides – – – – – -113 [<150]
  • TC/HDL ratio – – – – – – 5.8 [<5.0]

And, of course, as part of metabolic syndrome, one must be concerned about the fasting glucose . . .

  • Fasting glucose – – – – – 71 [<100]

My HDL had actually been worse a few years before that, in large part due to some bad habits learned in college and carried into med school.

Stay tuned for the current lipid panel results. We’ll see how much progress I was able to make since cleaning up my diet and starting an exercise regimen.  I’m nowhere near my fitness goal, but I’m hoping to see some progress.

Off to my physical exam

Posted in Preventive Medicine with tags , , on February 27, 2008 by Dr. CJ

You’ve probably heard the saying about how healthcare personnel (doctors/nurses, etc.) are the worst patients – rarely seek attention, rarely do the preventative exams that they encourage to patients, ignore advice when given to them.

It’s true . . . to some extent. I’ve encountered hundreds of much worse layperson patients, but there is some truth to that saying.

Well, I’ve decided to make use of the ol’ insurance coverage by scheduling a physical exam, really just to get my cholesterol rechecked. My “bad” (LDL) cholesterol has always been borderline okay, but my “good” (HDL) has definitely been low.
Now that I’ve busted my butt on diet and exercise, I’m expecting to see a significant improvement in both my HDL and LDL cholesterols. I’m expecting that all my lipid values will be in range now, including the TC/HDL ratio.

We’ll see if my advice to myself was any good.

I’m hungry . . . I always eat breakfast.

Do I HAVE to work out today?

Posted in My training updates with tags , on February 26, 2008 by Dr. CJ

Funny how the mind works. I was feeling quite unmotivated to do anything yesterday. After needing to leave the house too early to fit in my morning workout and then working all day, all I wanted to do was kick back and relax last night, especially since I would have numerous sleep disruptions being on call last night. I had just fit in a great workout the previous night, but knew I wouldn’t be able to do weights tonight, thanks to my schedule.

Since I don’t hold myself to a rigid workout schedule like some people do, I give myself the freedom to pick those lazy nights. My life is far too unpredictable with work demands, etc. to ever stick to a weekly schedule. So, I just aim to do cardio most mornings and weights 3 nights/week.

Then, my wife gave me a mini pep-talk and hopped on the elliptical.

Say no more . . .

Once I started working out, I fell into a groove and had a really good time. I made some improvements in some lifts and felt some good muscle burn that makes it all worthwhile. Can’t wait for the DOMS!

Some times it just takes a little extra motivation to get things going.

“The Biggest Loser” and reality TV deception

Posted in "The Biggest Loser", Rants and Raves with tags , , on February 25, 2008 by Dr. CJ

Television is notorious for its sensationalist approach to presenting news and other programming.  When in the business to keep people glued to the screen, they are going to use nonsense teasers and other trickery to keep viewers glued to the screen through another set of sponsor’s commercials in order to get to the punch line.  This situation has been rampant for years.

Then came so-called “reality TV“.  Obviously a misnomer, there is nothing “realistic” about “reality TV”.  Examples abound.  These so-called “reality” TV shows have rightfully come under scrutiny for their contrived scenes that are obviously intent on stirring up some controversy and drama in an attempt to retain viewers.

The producers have to appeal to the voyeuristic nature of TV viewers – plenty of people apparently live lives that are so boring that they need to live vicariously through their television.  In a sense, then, they are asking for this fake portrayal of human experience.

So, what about “The Biggest Loser“, a hit amongst those interested in weight loss and fitness for whatever reasons?  How much goes on behind the scenes when you’re watching someone waste away on the TV screen weekly?  An editorial in the Journal of the American Dietetic Association titled “When Overweight and Obesity become ‘Reality’” describes some of the sly production waves-of-the-hand that occur unbeknownst to the viewers, without specific reference to a particular show but instead making vague references.

The author references reports by participants of a particular weight-loss show who describe severe weakness and dehydration, while the viewers only saw their dedicated diet and exercise habits portrayed in a healthy light.  Also, the winner of the first season allegedly regained 7 pounds within days of the finale by simply rehydrating with water. (See links at end of post

Obviously, there are unhealthy weight-loss methods being employed in a situation like this where individuals are competing for a significant monetary prize.  Of course the networks and the shows cannot outright encourage these methods, but they are creating an unhealthy competitive environment that all but encourages these drastic methods.

Here, the producers have a unique opportunity to provide an educational service to the viewers, to offer a glimpse into what it takes to change one’s life by diet and exercise.  Unfortunately, it is instead a bit of a freakshow due to the sensationalist perspective that is presented to the viewers rather than the real-life perspective.  

Most viewers should be savvy enough to detect the fraudulent presentation of these stories – we know when we’re getting real “reality” programming – I’ve yet to see it.

More motivational success stories in weight loss

Posted in Motivation with tags , , on February 24, 2008 by Dr. CJ

I find that it helps once in a while to  read about how other people achieve their success with weight loss, not only to see what techniques they use, but also to reiterate the idea that it’s possible for anyone in any state of health to take charge and transform their bodies.

Instead of looking at the “young bucks” today, let’s look at the “over-40” crowd.  Though metabolism slows with age, there is never an excuse not to work towards improving your body.

First, a woman in her 50’s who struggled with weight gain in her 40’s, but turned the tide by cleaning up her diet and hitting the weights.

Then, this amazing transformation, not so much by his incredible results, but because of his age.  This 65-year-old man achieved incredible results with a disciplined plan that evolved as he learned how diet and exercise affected him.  Note especially the effect this transformation had on his blood pressure.

It can be done . . . by anyone.

Value of whole grains

Posted in Diet with tags , on February 22, 2008 by Dr. CJ

Carbohydrates get all the negative press. . . perhaps for good reason.  Simple carbohydrates are certainly not friendly to the body in the sense that they create a high-sugar load in the bloodstream, compared to a more gradual increase in sugar from complex carbohydrates (e.g. whole wheat, whole grain). 

Here’s a study suggesting benefit from a diet high in whole grains in reducing abdominal fat and reducing a marker of inflammation that has been implicated in heart disease risk.
