calorie deprivation - Page 2

post #31 of 38
Somehow, I ended up at this site recently, www.realage.com and with nothing better to do, took there test that is supposed to give your true age relative to your chronological age based on diet, activity and vices such as smoking and drinking levels.

I ended up about 1 year younger than I really am according to the survey, the interesting part?

I am 5'6" male and have weighed in at between 140 and 143 forever. I try occasionally to GAIN weight and fail every time. On the other hand I can eat or not eat what ever I like and my weight does not change much.

"The survey says!" I'm overweight for my size.

Go figure!

edited, forgot to put in the site reference.

This has been an area of hot research over the last 5 years or so. Caloric restriction has been associated with increased life span in several animal models. The mechanism of action here is difficult to determine, as you can imagine. Many seem to feel the reduced free radicals is a contributing factor.

I must point out that genetics, too, can play a role in promoting longevity. A recent paper from my old lab underscores this:

Science. 1998 Oct 30;282(5390):856.

Extended life-span and stress resistance in the Drosophila mutant methuselah.

Lin YJ, Seroude L, Benzer S.

Division of Biology, California Institute of Technology, Pasadena, CA 91125, USA.

Toward a genetic dissection of the processes involved in aging, a screen for gene mutations that extend life-span in Drosophila melanogaster was performed. The mutant line methuselah (mth) displayed approximately 35 percent increase in average life-span and enhanced resistance to various forms of stress, including starvation, high temperature, and dietary paraquat, a free-radical generator. The mth gene predicted a protein with homology to several guanosine triphosphate-binding protein-coupled seven- transmembrane domain receptors. Thus, the organism may use signal transduction pathways to modulate stress response and life- span.

The best thing about the 6' 115# guy is his waning
testosterone level and lack of interest in procreation. Let them kill themselves off and stiffle this lunacy. Before I run out and invest my 401K reserves in "Depends", I will continue to savor each and every moment in life; hopefully succumbing to my demise in a blaze of glory. We can only hope, after all.Get hit by a bolt of lightening and you don't get time to think about it. Lie listless on a bed oblivious to the world about you, praying for death, but belonging to that exclusive "oldest people in the world club" bears no interest for me. Give me quality, not quantity!

There are also mutations in rats and mice that are directly linked to overeating and obesity. Some of these same mutations in rodent models have been discovered in obese humans. The figure below is from an article in the latest issue of News in Physiological Sciences, (Schmidt, Ingrid, vol 17, June 2002, 115-122).

No, it's not a picture of me.

Hey Sugar,
You realise that's what he'll look like in 30 years!

Well hopefully I'll be around to judge for myself, and if so well then I'm sure I can keep him active enough to avoid said circumstance.
