Weight Loss and Dieting: Critical Mistakes (Part 2 of 8)

Exercise is a Bad Word

Why do we groan when we hear the word ‘exercise’? Because we aren’t used to moving our bodies on a regular basis and it takes a little effort, namely, getting up off the couch. Without exercise, losing weight will likely take you three times longer or more. All you have to do is move. Seriously. This is the basic concept. And if you’re going to get on board with attempting weight loss, why not fire on all cylinders? If you’ve decided to try it, the most important thing to remember at this point is to focus on cardio. That means getting your heart rate up for a prolonged period of time. Power walking or running will accomplish this! If you are walking fast enough that you can barely keep up a conversation, you’re doing it correctly. You don’t have to run, but if you’re looking into doing a little running, a great place to start is with a free app like Couch to 5K. You turn it on with your music when you start walking, and a little voice will give the commands “start running” or “start walking” intermittently.

The program will very gradually lengthen the running time and reduce the walking time over a period of weeks, until you are running the equivalent of 3 miles at one go. I recommend at least 30 minutes of cardio at least three times a week as a goal. And if you want to do more after reaching that goal, do it! Other cardio exercises can include hiking, any sport that involves running up and down a field or court, Zumba or aerobic classes, spinning, etc. Find something you can stick with for life. Do you have kids? Walk or run with that stroller, put your kid in a carrier or a wagon, or encourage them to run along with you (depending on their age). And again, once you’ve trudged through a month of forcing yourself to move, it will become second nature. You may even start looking forward to it!

What Exactly Is Cholesterol, And How Does It Affect Me?

Cholesterol

One question I am asked often by patients is, “What exactly is cholesterol, and how does it affect me?”

Cholesterol is a molecule that is made by the body naturally and is used in several important processes.  This includes the production of cell walls, hormones, and  Vitamin D, among others.  Our bodies produce it on a daily basis and while it’s very necessary, like so many things, too much is unhealthy.

A good portion of the cholesterol in our bodies is actually made there, however some comes from our diet.  Plants don’t contain a significant amount, however animal products do.  Since we can’t genetically change how much we produce,  a healthy diet low in animal fat is the best step most of us can take in keeping cholesterol levels safe.   However, because some people naturally produce more cholesterol than others, medication is often required to maintain safe levels.   I have even had patients with vegetarian diets who have levels outside the safe zone.

Why medication? We have learned over the years as we advance medically that higher levels of cholesterol are positively correlated with higher risk of heart disease through “clogging” of our arteries, both in the heart and the rest of the body.  High cholesterol is directly linked to heart attacks, peripheral artery disease, hypertension, stroke, atherosclerosis, and even diabetes.  We use several different types of medications which work in different ways, to keep the numbers in a healthy range when required.

What level is the goal? We typically combine 4 levels to determine a patient’s risk, as well as the need for and type of treatment.  Total cholesterol levels are best under 200mg/dl. However, 3 other molecules are important to consider as they are directly involved in the metabolism of cholesterol.

HDL and LDL are actually molecules that transport cholesterol and triglycerides in the body, we use them a marker for treatment.  High Density Lipoproteins (aka HDL) actually has a protective factor in higher numbers, so  we like to see a value over 40 mg/dl.  Low Density Lipoprotein (aka LDL) has a negative effect at higher numbers so we like to see it under 100mg/dl generally.

And last but not least, are triglycerides.  Triglycerides are actually lipids, which is another naturally occurring molecule like cholesterol.  It’s easiest to consider triglycerides as simply fat in your blood stream.  Too much, and arteries begin to become compromised leading to the same diseases as mentioned earlier with cholesterol. We like to see Triglyceride levels under 150mg/dl.

The combination of the numbers is much more important than any individual number, so we generally check these as a group with a lab test known as a “Lipid Profile”.  If levels are good, then it can be checked once a year safely.  If levels aren’t desirable, it is often checked more frequently as changes are made to diet or medication.

I hope that this has helped to explain a bit about what cholesterol is, and why it’s important to keep the levels safe through diet if possible. And if not, through the help of your doctor. There are always many factors to consider when considering treatment.  We would be happy to talk with you in person about this topic, or any other topic regarding your health,  at our Convenient Care Clinic.  Give us a call to schedule a visit!
