Also a handful of researchers in the study of long-term impact, he oversaw a group of about 50 adults who had been doing calorie restriction diets for at least a decade.
“Most are middle-aged, but have the cardiovascular profile of a teenager,” he said.
Blood pressure, cholesterol, blood sugar and insulin levels are low, while all the so-called “good” cholesterol remains high, he said. Diabetes and cancer rates have fallen too.
Studies published earlier this year point to another, specifically related to age and benefits.
One shows that reducing caloric intake by 20 percent reduces damage to DNA and RNA oxidation caused by half, compared with control groups.
Oxidative damage to DNA, proteins and other cellular building blocks are accumulated over time and are believed to be one of the main drivers of population aging.
A second study by Fontana, published in July in Aeging Cell, shows that a combination of reduced calories and limit your intake of protein reduces the levels of insulin-like growth factor, commonly known as IFG-1. (more…)
