“Speaking of humans,” Fontana added, “if you are lean because you are exercising, of course you are doing good, because you’re preventing types of diabetes, some kinds of cardiovascular disease and maybe some types of cancers. But the data suggest that calorie restriction is more powerful. And the people on C.R. are more powerfully protected from diseases than the exercisers.”Fontana connected his point to his continuing observations of some Calorie Restriction Society members. “In terms of cardiovascular diseases — the No. 1 cause of death; 4 out of 10 people die of it in the U.S. and Europe — we know that they will not die of cardiovascular death,” Fontana said. His subjects have cholesterol around 160, blood pressure around 100 over 60, high HDL, low triglycerides and very low levels of inflammation. “So these people won’t develop these diseases,” he said. “And I think that’s an important finding. Because every day doctors are publishing hundreds of papers on circulation research and medications that are lowering blood pressure or cholesterol by a small bit. And here we have such a powerful intervention that is basically cleaning out the arteries.” At Tufts, Susan Roberts, the lead investigator, echoed this position, saying that the study will probably have greater effects than the average clinical trial. “I don’t know why anyone would take drugs when they could do something like this,” Roberts said, referring to Calerie.-link
A nice article regarding CR in humans, this is only a small interesting bit.
