I do have to confess that a little exercise makes me feel a lot better. I'm just not sold that a lot of exercise is necessarily good.

I wish I'd been into martial arts and low carb at the same time, then I'd be in a better spot to judge. But I was constantly injured (by activity, not fighting) and getting pretty badly crippled up with arthritis, unfortunately on a high carb, gluten-filled "healthy-ish" diet at the time.

Yes people keep misquoting Gary Taubes on that one. All he said was that the current science doesn't match the prevailing cultural wisdom because the science is sloppy and all over the map. He says we need better science.

That's not the same as saying, the science proves exercise this or that.

Honestly sometimes I think the health policy world's corruption of science spills over into everything and makes everyone sloppy about what science ( or science writers ! ) say. It's like contagious.

Does it then get stashed as fat?
It has to do with the difference in metabolism between different types of muscle fibers. Glycolytic fast twitch fibers, which are only activated by high intensity demand, consume the most glucose. Glucose that is cleaved from glycogen inside muscle cells does not leave the muscle. It's either metabolized inside the cell or the unused portion is converted back to glycogen. If it's consumed it will be converted to pyruvate (substrate for the Krebs cycle) and ends up excreted as water/CO2 or eventually recovered from excess lactate at a high net energy cost (the Cori cycle).

Exercise that you can keep up for an hour isn't HIT. Any exercise that fatigues any fibers will consume some glycogen but HIT does this very rapidly.

Yes, that's it. Makes you feel good, and that's reason enough to do it. It makes me feel good too.

Default Exercise may help slow aging process

I've been away from this board for a couple of weeks, so I don't know if someone else has posted this.

Exercise may help slow the aging process.
Intensive exercise protects against telomere shortening, according to an intriguing new study appearing in Circulation. German researchers studied young professional runners, middle-aged athletes, and age-matched controls who did not exercise regularly.

“The most significant finding of this study is that physical exercise of the professional athletes leads to activation of the important enzyme telomerase and stabilizes the telomere,” said Ulrich Laufs, the study’s lead author from Saarland University in Homburg, Germany, in an AHA press release.

“This is direct evidence of an anti-aging effect of physical exercise. Physical exercise could prevent the aging of the cardiovascular system, reflecting this molecular principle.”
