What do the sluggardly and slothful wish for the most, aside from a Mountain Dew IV drip and Kari Byron to feed them Cheetos while they play Halo 3? That's right, to be able to ingest a pill to give them all the benefits of exercise without, you know, having to move. That glorious day may just have come closer, as scientists have discovered a chemical that fools the body into thinking it's just had a workout:
The drug, according to the researchers, changed the physical composition of muscle, essentially transforming the tissue from sugar-burning fast-twitch fibers to fat-burning slow-twitch ones -- the same change that occurs in distance runners and cyclists through training...
"It's an amazing piece of pharmacology," said David Mangelsdorf, a pharmacologist at University of Texas Southwestern Medical Center in Dallas, who was not connected with the research. "You're getting the benefits of exercise without having to do any work."
However, before you get yourself all winded in an attempt to celebrate, please note that this is still in the "test it on helpless rodents" phase of things; until and unless this line of research pans out, you will still have to occasionally hie your carcass off the davenport if you don't want to keel over whilst grabbing for the packaged, orange-powdered corn bits you love so well. And no, Kari Byron isn't coming over to bring them to you. Kari Byron can have anyone she wants. She's not going to hang with people marinating in their own Ritz Bits, if you know what I mean, and I think you do. Yes, life is unfair. Or at least will be until this exercise chemical hits your local pharmacy.

Hmmm, maybe there's an idea for a story there...

Beware Disc Golf. That stuff is addicting. Might just get you to exercise. It is of the devil! But too late.
Now if I just didn't suck.

(Oh scientists: Can't we agree that the current rodent super races are sufficient?)

besides, I'm still waiting on virtual reality and the cure for baldness before I can get a six pack sitting on my ass

These drugs may be an effective way to combat the effects of freefall on muscle atrophy.

AICAR (5-aminoimidazole-4-carboxamide ribonucleoside) simulates AMP - or, basically, makes your body think that it is currently energy deprived (because the ration of ATP to AMP lowers). One response is to increase the rate of glucose metabolism - and likely fat metabolism - which would provide the plausible basis for change in muscle-fiber composition.
BUT (many buts). For that alteration to cause e.g. weight loss requires that the animal be exercising; very few couch potato mice. And to make things worse, we recently found that repeated hypoglycemia (which is akin to taking AICAR several times) leads to a *doubling* of body weight, and assorted other problems, in rats (which are closer to humans than are mice). I can provide .pdfs of the work if anyone actually cares ;)
