The Miracle Treatment You’ve Always Known

by Doug DeSalles on March 5, 2013

Almost everything that comes along seeming too good to be true is just that. Thankfully, there are exceptions. Once in a while something pops up that’s everything it is cracked up to be. This miracle treatment is exercise.

Exercise is the second greatest health intervention known to medical science. The #1 health intervention is stopping smoking, however, so it’s not available to all. While exercise has long been known to be good for us, only in the past few years have researchers nailed down just how wonderful it is.

It turns out that simple exercise makes us feel good (and look better) but more importantly – it really and truly protects against a plethora of diseases. And we are talking about some of the biggest killers: heart disease, diabetes, strokes, dementia, and depression. Exercise has been proven to aid memory while reducing obesity (with all of its contributions to disease states).

The news on exercise is so good that we should go on a bit about it – starting with the fact that significant benefit is gained by only 30 minutes of moderate exercise five days a week (for a 150 minutes a week total).

Defining “moderate” has always been a bit tricky. What do they mean by “moderate”? Exercise researchers talk about “metabolic equivalent” (METs) as a way to calculate how much a given activity compares to resting. “Moderate” exercise works out to 3 to 6 METs. This can be achieved by walking 100 steps per minute. This is easy to gauge. For more detail on how a given activity stacks up in METs one may look up a chart of activities.

Note: such charts reveal some surprises. Many activities reach high levels of METs [examples: cross country skiing (16), fast swimming (11), jogging 5mph (8)], but some are less impressive than one might hope. Downhill skiing only rates a 6 (I think this must vary tremendously skier to skier) but far worse “vigorous sex” only clocks in at 1.5 METs. Contrary to what you may have been told you must not count on bedroom activities to meet your exercise requirements. We do recommend it for other reasons however – such as meeting your romance and fun requirements.

Another bit of good news is that researchers now believe that you can slice that 150 minutes a week almost any way you choose and still derive a benefit. Couple this to a third bit of welcome news – value can be had for exercise bouts as short as ten minutes – to see that there are many regimens that will help a person.

New data seems to have settled some age-old debates on exercise. Large well- designed studies have now established that muscle strength and aerobic fitness really do make independent contributions to health. You benefit from jogging AND from pumping iron.

The numbers we can now place on health benefits are impressive. Exercise moderately and your risk of type II diabetes drops 58%. Exercise makes cells more responsive to insulin while muscle contractions help get sugar out of the blood and into our cells where it belongs.

With a regimen of moderate exercise the risk of death from premature heart disease drops 40%. The same can be said for the risk of a heart attack!

Many healthy effects from exercise come from positive actions on fat metabolism. Exercise knocks down the levels of fat in our bloodstream. One study showed a single 2 hour bout of exercise reducing trigyceride levels 25%. Cholesterol levels – particularly the very low density lipoproteins (VLDL aka “bad cholesterol”) – showed double this reduction.

Somewhat unexpectedly – studies on memory now show that even moderate exercise improves recall 15 to 20 percent. And if all this has failed to convince you to get up off the couch let’s add the fact that it can help with cancer risks as well. We shall save this last for the next blog, however and go out the way we came in: simply exercising your body moderately pays gigantic benefits to your health.

You do not need to be training at an Olympic level – moderate exercise will help. You do not need to spend hours a day to see a benefit – 150 minutes a week will help (including workouts of as little as ten minutes a crack). By doing this your risks of heart disease, diabetes, stroke, dementia, cancer and a lot more are significantly reduced while you are made to feel better, and look better.

Exercise seems too good to be true, but it is not. And even if sexual activity is not as good as cross-country skiing (from a metabolic standpoint a least) we still encourage it. We will have more to say about that soon.

A New Angle on Cannabis

by Doug DeSalles on October 19, 2012

The US Justice Department could not keep track of guns that went to Mexico, and contributed to the bloody drug war south of the border (which has now killed as many Mexicans as American lives were lost throughout the Vietnam conflict) but is HAS been able to locate and harass the cannabis dispensaries in California. We don’t want to weigh in on that issue today, but we would like to enlist the reader in the survey: How Does Marijuana Affect Your Sex Life?

We got curious after hearing from some people that cannabis improved their enjoyment of sex. Given our present legal climate, where cops playing doctor insist (contrary to the mass of evidence) that cannabis has no legitimate medical uses there is zero chance that any prospective, double-blind study will be done on the subject.

So, a survey is probably the best we can hope for, short term, to advance the discussion on cannabis. Anecdotal evidence is not terribly convincing, but it certainly has value. We hope readers will participate in the survey. We will try and evaluate it next month. In the meantime, here are a few responses:

Yes for me! Weed enhances my libido and my sensitivity; some of the best sex I’ve had has happened while stoned.

I always experience an increase in desire and pleasure when having sex. I have a few friends who experience the exact opposite probably because they smoke every single day from when they wake up until bed. So it probably depends upon frequency of usage.

As a first time user I found marijuana to increase my libido.

I can say for me and all my friends who have had sex while on marijuana it definitely makes sex 10 times more enjoyable.

I do relate to the “zombie like sex” I read about posted by a few women. That happens often when you have sex while too high.

I smoke marijuana every day, and by doing this I always find that I am horny when I get high, always…. marijuana is a great sexual enhancer.

I am an older woman…… the addition of MJ to our sex life has allowed me to experience very enjoyable orgasms.

We would like to see many more comments. While some people have noted a decline in sexuality on cannabis this appears to be a minority opinion, more than balanced by those who find it to be a sexual enhancer. Please, add your opinion and we will try to summarize this next month.

The Business of Testosterone

by Doug DeSalles on May 11, 2012


“Surge in testosterone treatments raises alarm”

That headline on a Bloomberg News item grabbed my attention. The first paragraph of the piece got right to the point. Noted author Shannon Pettypiece (no, that really is her name) “In what may become one of the most sought-after sex enhancement treatments since Viagra 14 years ago, new testosterone drugs are in hot demand”.

The trouble is that in the entire article, no justification is provided for speaking of testosterone in the same sentence as Viagra. Bloomberg is a business publication not one devoted to medicine, but I’d have expected that after an opening implying that hormone supplementation is in hot demand for “sex enhancement,” at some point the reader would learn why that was stated in the first place. But no luck.

We do learn business-related facts; prescriptions for testosterone have doubled over the past 6 years to 5.6 million/year in the US. We learn that over the next five years sales are expected to triple to 5 billion dollars. We learn that Abbot and Lilly are increasing their advertising budgets.

Thankfully, we also learn that medical experts are very dubious about all of this. Checking the levels of testosterone involve a notoriously unreliable test, and a Cleveland Clinic doc takes pains to note he only prescribes it for patients with a medical need. What a concept!

The issue of testosterone supplementation comes up weekly in my clinic. A while ago I decided that we would not be supplementing people unless they could a) produce lab tests showing they really were low and b) their doctor would simply not write a prescription for hormone replacement. So far exactly one person met the criteria, and after starting them on a gel we turned the management of that over to his primary care physician. We are not much into the testosterone business.

The reason for this is that despite the popularity of using testosterone to help erectile dysfunction it rarely works. We see many, many patients who have tried it, for example. Had it actually worked, they would not be coming to us.

There is no good reason why it should help most patients. If a man’s levels are in the normal range, boosting the levels above normal (or to the high end of the normal range) does not help him. Ask your local urologists. We certainly did and they were explicit about this logic. Everything I’ve seen supports their reasoning. Testosterone has more to do with desire than the actual mechanisms that produce erections. Oddly, this is true for females too! When the occasional man comes in with genuinely below-normal testosterone levels they have usually noticed a drop in libido, prompting testing.

No libido will produce a certain failure to achieve an erection. That I don’t dispute. The occasional man with this problem can (and should!) be supplemented. When this happens, their condition usually improves. The thing is, we are talking perhaps 3-4% of the ED patient population. The vast majority of ED patients have testosterone levels that are within the normal range.

So where do people (and Bloomberg writers) get the idea that male hormone is an ED treatment? Well, sex sells. Some men find that they feel improved energy levels on testosterone. Body builders in particular (as noted in the article) are pretty big on the subject. The same guys who fill out the pages of muscle magazines, who abuse anabolic steroids, are all for it. Hmmmm.

The drug companies are not going to quibble over this. It is claimed that 13.8 million Americans have low levels. Seems high to me! Men’s levels do tend to drop after age 45, as the ads on late-night TV keep reminding us, but five billion dollars in sales by 2017 looks pretty good to them. Note: Viagra sales last year totaled 2 billion, with Cialis is right behind at 1.9 billion. But both these medicines are effective for most men with ED. The class of medication (phosphodiesterase inhibitors) to which they belong will help perhaps 60% of men with ED. Compare that to maybe 4% for testosterone.

Testosterone, like any potent hormone, can have drawbacks. While no studies have ever shown (at least none so far) that extra male hormone can produce an increased risk of prostate cancer that remains a theoretical risk. As for BPH (Benign Prostatic Hypertrophy) standard therapy for men with enlarged and troublesome prostates is to LOWER their most potent forms of testosterone.

A former competitor (thankfully now out of business) used to supplement everyone seeking treatment for ED with testosterone cream. Everyone! Shameless staffers would tell patients it would add 30 yards to his golf drive. Steroid misuse can enhance athletic performance as anyone who follows sports knows. Some improvement of energy levels and/or athletic performance probably does take place with many men on testosterone.
But how much comes from the placebo effect? I sure do not know.

I will grant that some men surely think they do better with their ED from testosterone, but considering only 3-4% of those being treated actually have a need for testosterone supplements, I would say that most of these men are experiencing a placebo effect. After all, rich Chinese consumers are paying top dollar for powdered rhino horn (and helping wipe out the last of these mighty beasts) even though rhino horn is chemically identical to powdered fingernail clippings. But they swear it works, because when they tried it they felt better. We must do better than that as we have millions of men starting supplementation.

As I finished typing this, a clipping fell out of one my files that was remarkably appropriate. It noted that 9 years ago a panel had been being convened to examine the ever-growing issue of hormone supplementation. At the time Science magazine noted that the Institute of Medicine in Washington concluded that the efficacy of the treatment needed to be established, the adverse effects needed to be examined more closely and that in the meantime “men and their doctors shouldn’t consider testosterone preventative medicine against age-related symptoms”.

Although this all remains true today testosterone has climbed in the back door to become a billion dollar industry in no small part due to the matter of erectile dysfunction being a major “age-related” symptom. There is much to discuss before millions line up for $250 a month injections or Barry Bonds-like gels. We will have more to say about this in the future.

Of Old Mice and Men

by Doug DeSalles on January 14, 2012

The Mayo Clinic, famed for its cutting edge medical care, has conducted research that is being called revolutionary in the field of aging. Dr. Darren Baker’s work involved genetically engineered mice, but could be a breakthrough for homo sapiens. According to a recent article in Nature a strain of mice were developed that were afflicted a genetic disorder that produced the mouse equivalent of progeria, that strange disease that causes premature aging. As with humans afflicted with progeria young animals develop conditions associated with old age.

A certain molecule is produced when cells get old that prevents further cell divisions. This is one method cells use to prevent the runaway growth of cancer. The Mayo team cleverly figured out a way to induce cells that switched on the gene for the molecule to self-destruct. They did this by slipping a gene for another protein very close to the one producing the age-related molecule. The new gene was activated by the same switch that turned on the age molecule. When they exposed that protein to a drug it proved deadly to the cell. So it was the old cells could be made to selectively commit suicide.

No one was sure what selectively killing the old cells would do, but it so happened that the mice slowed their too-rapid aging in a spectacular way. Their muscles remained strong, their fatty tissues did not waste as fast and they did not develop cataracts. The effect was more pronounced the sooner in life the mice were given the cell killing drug, but older mice still benefited.

This approach is different to methods employed previously which have been based on either finding a way for cells to divide longer (with an accompanying risk of cancer) or suppressing chemicals the cell produces that cause damage via inflammation.

This new method is related to the latter approach however. The old cells killed by this technique were causing harm to nearby cells via an inflammatory effect. In the absence of the chemicals (the cellular equivalent of a fire alarm that turns on a sprinkler to douse the flames) the younger cells stayed healthier.

Tinkering with an organism’s life span is surely problematic. There are reasons why we are not immortal. This method raises the possibility that a healthier life can be extend in time. To my mind this is the cellular equivalent of the face lift that smooths wrinkles. After the procedure you are left with less material than what you began with, which itself is potentially a problem.

In this case the fewer cells remaining will also age and stop dividing, but while they live they suffer fewer untoward effects from molecules from those old cells and the inflammatory response they induce. So while one might not live longer one could experience a healthier, more vigorous old age. When people talk about living to 150 nobody has in mind living out 60 or so years as a 90 year-old

This experiment needs to be repeated. First on mice that are more normal than the progeria strain. Some mice strains live 3 plus years vs the normal two year life-span so they are the next logical candidates. This experiment has a long way to go before benefits to human health can made a reality, but it is exciting. A whole new approach to dealing with age has been opened up.
