Had a fascinating lecture today in Nutrition of Aging class...

We talked about calorie restriction and it's relation to life span. Apparently there are monkeys and mice on restricted calorie diets that live 2-4x longer than regular monkeys. Low cal/high nutrient diet drastically slow down the aging process, but the reasons are unknown. I suggested to my teacher it was because hormones like testosterone and IGF are lower in a caloric deficit, and she didn't even know that happened. You guys heard anything about it? Any opinions, reasons why it exists? I found it a pretty interesting lecture whereas I usually fall asleep in class.

Is it the same study that had monkeys and mice eat only every other day?

I thought it was something about free radicals

similarly why vegans/vegitarians tend to live longer, they consume less calories.

I actually heard about this a year or two ago, but it was people not mice who were experimenting on themselves. Quite frankly, they may live longer but they sounded a bit depressed about having to eat so little. Perhaps less calories=slower metabolism=less work on internal organs and such=longer life?

I was watching Penn & Teller Bullshit the other day, and they had on a guy that was on a big caloric deficit (or at least really low cal)...he was starting to get osteoperosis

I blame it on mcdonald's I blame it all on mcdonald's

i think when one of my profs covered it, he mentioned the reduced reproductive capability on caloric restriction. because energy isn't diverted to reproductive systems, things are easier for the body.

tize who wants to live to 100 anyway i would. if i were healthy.

evi1eddie i think when one of my profs covered it, he mentioned the reduced reproductive capability on caloric restriction. because energy isn't diverted to reproductive systems, things are easier for the body. we're going to die sooner if we more? shit i hope I survive into my 30s
