The New York Times introduces us to Canto and Owen, two rhesus monkeys on totally different sides of the calorie restriction spectrum. Canto who eats 445 calories a day is healthier and much younger looking than his buddy Owen who consumes 885 calories daily—Owen doesn’t appear happy about it. Some scientists believe the plight of Canto and Owen sheds serious light on the benefits of calorie restriction for humans. Michael Mason reports:
Researchers at Washington University in St. Louis have been tracking the health of small groups of calorie-restricted dieters. Earlier this year, they reported that the dieters had better-functioning hearts and fewer signs of inflammation, which is a precursor to clogged arteries, than similar subjects on regular diets.Anyone else want a pet rhesus monkey now?
In previous studies, people in calorie-restricted groups were shown to have lower levels of LDL, the so-called bad cholesterol, and triglycerides. They also showed higher levels of HDL, the so-called good cholesterol, virtually no arterial blockage and, like Mr. Linksvayer, remarkably low blood pressure.
“Calorie restriction has a powerful, protective effect against diseases associated with aging,” said Dr. John O. Holloszy, a Washington University professor of medicine. “We don’t know how long each individual will end up living, but they certainly have a longer life expectancy than average.”
Researchers at Louisiana State University reported in April in The Journal of the American Medical Association that patients on an experimental low-calorie diet had lower insulin levels and body temperatures, both possible markers of longevity, and fewer signs of the chromosomal damage typically associated with aging.
