Low-Cal Diet Extends Life... As Long as You Don't Eat
There has been a lot of research recently showing that a restricted calorie diet can extend the lifespans of various creatures. Sadly, it seems that as soon as they start eating again, the benefits are lost.
Research also shows that eggs are bad for you .. no wait, make that good. Wait, here is a new study....
Who knows what to believe half the time? A low-calorie diet is good if you need to lose weight, plain and simple. Otherwise, eat the amount of calories you need to maintain your weight. It's not an exact science, but if you avoid the junk food and make half an effort to eat sensibly, there shouldn't be much to worry about.
We'll live longer if we don't eat, drink, smoke, fuck and so on...

But what is the point of having life if you don't live it? Boring people may live longer, but they live less.
That brings up another issue... when does life stop being worth living?
This is the question that the euthanasia folks would dearly love society to answer... but they can't; it's an individual decision. This is part of the drive behind people getting living wills, durable powers of attorney for healthcare, and advance directive, etc.
I'm not quite to mid-life, without a single health problem. I run, work out, don't smoke, or drink to excess... and I have a living will, AND advance directives. Why? Because, as a physician, I have SEEN life that's not worth living (at least it wouldn't be for me), and I would never want to get to that point. I encourage people, even healthy ones, to think about a living will... and to have the necessary conversations with their loved ones and significant others. Once you're critically ill/vegitative, unable to make that choice for yourself, and others are trying to deal with the emotional trauma of your incapacitation... that is NOT the time to attempt an objective conversation about it.
Yes, you can diet, and deprive yourself of all the "good things" in life, but is that really a life worth living, particularly if it only buys you a small, arbitrary gain? Again, it's an individual decision.
I think I'll keep eating my cheeseburgers.
Even if a man chops off your hand with a sword, you still have two nice, sharp bones to stick in his eyes.
On my "lifesyle" change I had lost 60 pounds. I wobbled a bit and gained 5 back, but I'l losing 1-2 pounds a week again.
There is one things that keeps getting hammered into my head.
We don't need all the food we eat to survive or even be full. Once your stomach learns what it needs, it won't keep asking for more more more.
People with the "supersize" this and the "extra large" that are slowly killing themselves each time they order more than they need.
But let's face it. I'd rather die in my 60's then to live 20 years longer in a nursing home.
Just remember slashdotters, you can have ONE slice of pizza for dinner and still be ok for your daily caloric intake.

A study on dogs showed a 16% increase in life span for a calorie restricted diet -- thats a couple of extra dog years or perhaps decade or two of more life for a person. Sounds good, right? The problem was that the dogs had to eat 25% less than normal to get 16% more life than normal.
As someone who enjoys his kibble, I would argue that less chow = lower quality of life. So for 25% less quality of life, I get 16% more quantity of life. Sounds like a bad deal to me.
Moreover, the report said nothing about the energy levels of these poor long-starving mutts -- do starved creatures have any energy for fun and games? Due to the realities of physiology, I'd bet that a 25% reduction in energy input leads to a more that 25% reduction in energy available for discretionary, fun activities. On a restricted diet, a greater fraction of the meager intake is diverted to basic maintenance of the body.
I'm not saying that obesity is not a real killer of both quantity and quality of life. I'm only saying that restricted calorie diets come with tradeoffs.
Two wrongs don't make a right, but three lefts do.
I think some of the people here are missing the point of the research.
Scientists have known that restricting your intake of food helps leads to a longer lifetime. Note that the emphasis is not on eating correctly or better, but just less. Based on my limited biochemistry/metabolism knowledge, this is thought to be a consequence of how your GI system breaks down food and the long-term effect of the potent chemical processes on your body; this is also briefly restated in the article.
Where this differs is that they have shown that benefits can be had at any time in an organism's life cycle, indicating that something else is afoot. So no, this is not yet another study that says you should go on the Atkins/grapefruit/carrot soup/wicker chair & bagels diet.
Okay... we've uncovered yet another truth in nature... organisms are designed to withstand famine.
Although the human intellect has improved over the millenia, the genetic script for our bodies has been nearly unchanged since the last ice ages. We only see organisms today that can resist famine because evolution has weeded out those strains that couldn't survive. If the creature can't find food or water, it's in the best interest to "pause" some life functions so you can survive until nourishment can be found.
Our bodies are evolved to be fat-storage machines; we have to, because nature can never guarantee the next meal. Our noses, though not as good as some other creatures, are still very receptive to spoiled food. Salt tastes good because our body needs it for cellular processes. Sugar tastes good because it's high energy "food" rare in nature.
But we've broken the cycle. Our insulin proceses the sugars, but never before has so much sugar been available, so now we see diabetes where our insulin receptors are over-exposed and develop a tolerance. We still have fight-or-flight mechanisms, but most of us live such a mundane existance, we release stress chemicals over the slightest event. Then we try these starvation diets, and our bodies don't burn the fat, because it thinks there's real hard times ahead, not realizing we have more food than we can eat.
It's a battle of intellect over evolved chemistry... but slowly we understand what is really going on behind the scenes, and with knowledge comes the power to correct it.

You can live to be a hundred if you give up all the things that make you want to live to be a hundred.
