The MIT Technology Review recently interviewed researcher John Holloszy: practitioners of calorie restriction [CR] are "are powerfully protected against the diseases of old age, such as heart disease. They have low levels of cholesterol and triglycerides and extremely low blood pressure - similar to a young child, around 100/60. As a result of the low blood pressure, they have less strain on the arteries, which are much more elastic than usual for people of their age. Their hearts resemble the heart of a person 17 years younger. They also have very good insulin sensitivity, so they are not going to get Type 2 diabetes. ... As we get older, we get an increasing amount of inflammation, which is probably a very important part of the aging process. [CR practitioners] have very low levels of inflammation. C reactive protein, for example, is a marker and cause of inflammation. An average value for a middle-age person is about 2.5; but [CR practitioners] have levels of 0.2. It's just amazing."
