New Drug Mimics the Beneficial Effects of Exercise 492
Zothecula writes "A drug known as SR9009, which is currently under development at The Scripps Research Institute, increases the level of metabolic activity in skeletal muscles of mice. Treated mice become lean, develop larger muscles and can run much longer distances simply by taking SR9009, which mimics the effects of aerobic exercise. If similar effects can be obtained in people, the reversal of obesity, metabolic syndrome, and perhaps Type-II diabetes might be the very welcome result."

Biology being what it is, it's reasonable to think that the health benefits of exercise are a multi-factor phenomenon and that any one chemical will deliver fewer benefits than the real thing.
Then the odds are that the drug won't be bio-equivalent to the chemical signals released by real exercise and will have side effects as a result.

Steroids, contrary to the public perception, can be used responsibly and with few health consequences, especially by men, to more easily lose fat and gain muscle.

A drug that tricks the body to respond as if it has been exercising will work on all muscles. Real exercise only works on the muscles that you use. Overuse of this drug would be expected to cause muscle growth where you don't want it. Bulk up those facial muscles.
Sure, in limited cases, this could be great. I'm thinking of cases where people can't exercise, using this in low doses to reduce the length of rehabilitation. Stuck in bed for a month or two due to a car accident? This is for you.
Of course, if it works, it will be abused. Need to get that extra edge for the Tour de France?

From TFA:
Previous studies on mice lacking Rev-ErbA showed decreased skeletal muscles, metabolic rate, and running capacity. Such mice appeared fated by their genetics to live as couch potatoes.
When Burris' group administered SR9009 to these mice to activate the Rev-Erb protein, the results were remarkable. The metabolic rate in the skeletal muscles of the mice increased significantly. The treated mice were not allowed to exercise, but despite this they developed the ability to run about 50 percent further before being stopped by exhaustion.
So they created some broken mice and then treated them with a drug that reversed what they broke. And, what do you know? The effects were reversed too.
I'd like to see a followup on unmodified mice to see if they also benefit. If Rev-ErbA is already present and active at normal levels, the drug may not do anything.

I could be reading this wrong, but it looks like life expectancy is trending upwards since the 50's. http://www.infoplease.com/ipa/A0005148.html [infoplease.com]
You could be reading it wrong. Note that it explicitly says "life expectancy at birth". There has been a lot of criticism of this sort of things from statistics-enabled researchers, who point out that almost all of the life-expectancy gains in the past century have been through elimination of most early-childhood deaths. Life expentancy at birth has increased, but the life expectancy of someone 30 or 60 years old hasn't actually changed much.
There has been a bit of publicity around related topics lately. Thus, there has been a lot of discussion of the apparent fact that the increase in mammograms has produced no measurable increase in lifetime, just an increase in medical bills for the testing (and the "treatment" of false positives ;-). Similar statistical problems have been reported for prostate-cancer screening, and for an assortment of other medical tests.
Another statistical trick used to make things look better than they are is the common practice of giving cancer survival rates in terms of survival 5 years after diagnosis. This means, for example, that if you were to come up with a new test that diagnoses a cancer 5 years earlier than any existing test, your test would result in a 100% "cure" rate even with no further treatment, and no change in the death statistics. I've heard a couple of interviews in which the interviewer points out this problem, and the interviewee just continues talking about the same "5-year survival" figures.
In general, it seems that if you're over 10 years old, modern medicine really hasn't done much in increase your (statistical) lifespan, though it is sometimes fairly good at extracting money for treatments that don't increase lifespan.
(Perhaps some of the treatments improve quality of life, but the statistics for that don't seem to be widely studied or reported. It might be interesting to be shown wrong in this regard, however. OTOH, there has been a bit of media coverage lately of the problems with "treatment" of false positives.)
(And a more general problem here is that the general public -- and the media -- is generally ignorant of even the most basic statistical concepts.)

I literally lost 25 pounds walking a half hour a day and cutting out the dairy, wheat and a lot of the superfluous carbs. At no point did I feel sick, tired or particularly hungry, in fact I felt and looked better than I had in years as my digestive track went back to a healthier state and my blood wasn't full of the crap that's in the usual American diet.
It doesn't take that much work to eat and live healthily, it just requires some commitment to your heatlh and a willingness to give your body the kind of foods and exercise that it evolved dealing with. You don't need to eat just because it's dinner time, you eat when your body gets hungry, and I mean hungry, not just a craving to eat.

You are young and healthy and have never met anybody who was dealt a bad hand genetically or suffered a crippling accident or infection. Get north of 50 after a life of minor accidents, or hang out with young people who have two pacemakers, biweekly seizures and a heart that leaks blood when it beats, and you'll find that not everybody is physically capable of what you envision everybody as able to do. Sometimes it is as simple as a quick infection of the pericardium and heart as a young child. Other times it is something work related like the other car driving into a ditch atop your ATV while you were both pursuing a suspect in the dark. It can even be their fault: I've known people thrown out of the back of pickup trucks who live with a solid brace bolted into their spinal column. It doesn't matter: it is their reality, and they have to deal with what they can do. Eating well, exercising in the pool, doing exactly what their doctors tell them to, but still unable to really be fit.
These are the people who need help beyond mere "exercise and a change in their diet". There are people living beyond your sphere of experience who can benefit greatly from things like this.

There is a large segment of people that will say things like " running causes arthritis in your knees". This is what I was directing my comment at. Running, on its own, does not cause your knees to become weak or necessarily damaged. There is a chance of an injury occurring, but that does not mean that people should not exercise in general.
there is nothing different from "exercise over time leads to injury" and "being alive for a long time leads to injury" . Sitting at a bus stop has risks, sitting in your house has risks, walking anywhere can have one bad step that can do absurd amounts of permanent damage. None of this means that exercise will cause injury.
I have a permanent injury to a shoulder, so I somewhat understand your perspective .It happened from several odd falls, and then one day it came out while lifting a bucket and tore things up when it slid back in. I will never be able to do a pullup unless I can nearly one arm it with the other side.
My statement is not ignorant, it was targeted at people who are misinformed and loud, and the opposite of ignorant. Like I said, because of science. If it is arrogant, it is only because of the number of times I have to hear the nonsense about the cause (not risk) of injury being exercise.
