Scientists believe that our slow metabolic rate is the key to explaining our relative longevity.

Quote

According to a new study, humans and other primates such as chimpanzees burn calories at a rate that is only half that of other mammals. This fact is believed to explain why we live a lot longer and grow up more slowly.

Actually, bowhead whales are the longest living mammals. They can live up to 200 years.

The Bible says the people of old times lived to 1000 years.

The problem with that is we have no idea how ancient people's idea of time was measured. Add that to the fact that the Bible is scripture (not scientific).

It would seem that if we burn calories at a slower rate then we shouldn't need to eat so often as we are currently being programmed to do.

Also we shouldn't need such a huge amount of daily calories just to stay alive (as we are commonly told)
But I would think nutrition, hygiene and better environments do a great deal too.

When I read that article on why primates live longer (slower metabolism) it struck me that that might explain why calorie deprivation, which slows metabolism, lengthens mouse lifespans but doesn't seem to work with us.  We've already evolved it.

Yeah lets just eat less and sit on our butts so we don't burn any of those pesky unnecessary calories they say we need to live healthy productive lives. Who needs people who do those demanding jobs that require massive amounts of physical exertion and have to have a higher caloric intake to maintain the energy level needed to do so. It's a waste of food.

No need to get snide with me.
For the average joe who doesn't work in construction or farms, I simply think that 1500 to 2000 calories is excessive. If all you do is, as you put it, sit on ones butt, then one doesn't need 2000 or even 1500 calories.

But yes, you are right, we would do well to eat less and not eat at rigid times OR eat strictly three + meals a day unless it is absolutely needed.

Honestly, I do think nutritionists should take into consideration everyone is not the same. When I was in the hospital for heart failure they always send a nutritionist in to talk to you about your diet. Most all my life I have been thin, I rarely sit down to a meal and more or less nibble on healthy food...quite the opposite of most people with heart problems. Her recommended diet was almost three times what I would normally eat in a day, even when I was an athlete.

This study seems to ignore the fact that most animals that live in captivity generally have a longer lifespan than in the wild. This is mainly due to a lack of predation, a steady food supply and advanced medical techniques. It is basically the same reason human lifespans are generally increasing as we are able to remove many of the threats that a life in the wild entail.

If you going to sit on your butt all day !! than really you can do with less than 1,000 and still feel not hungry and be healthy.But in order to live long life you have to starve your self go days with out eating and have no meat because of calorie restriction.

Every time you eat your body release free radicals , this is like pollution and over time damages organs and causes cancer.

WE LIVE LONGER THAN MOST BECAUSE...

We wear pants.

We are so fabulous, that other mammals can't handle our fabulosity, and they die, while saying: "Aaaaahhhh...I....*cough*....regret not wearing*COUGH*...p-pants..."
