Eating Less Extends Life Span
The team showed that hormonal changes that occur when mice eat significantly could extend the lifespan of rodents.
"We know that being lean rather than obese is protective from many diseases, but key rodent studies tell us that being lean from eating less, as opposed to exercising more, has greater benefit for living longer. This study was designed to understand better why that is," said Derek M. Huffman, the study's lead author.
However, Huffman did warn that the study applied only to rodents, which are different in some key ways from humans. Previous studies using mouse model had shown that exercising did prevent an early death from disease, but does not extend the maximal lifespan.
Together, these findings indicated that caloric restriction protects against disease better than exercise does, and has the added benefit of extending the life span of some rats.
Physiologists have been trying to unravel the reasons for this, and two major theories have emerged.
One theory is that exercise places stress on the body, which can result in damage to the tissues and DNA. Another theory is that caloric restriction leads to physiological changes, which benefit the body.
Huffman and colleagues designed a study to examine the roles of exercise and caloric restriction, singly and combined.
