The open access paper noted here is an example of present day intermittent fasting research, in flies in this case, in which researchers attempt to obtain a better understanding of how this dietary adjustment influences the pace of aging. The paper caught my eye for the examination of intestinal function. If you have been following the field in recent years, you may recall that the research community believes that intestinal function is central to the aging of flies, probably much more so than is the case in mammals. We can say that flies die from intestinal dysfunction in the same way we can say that humans die of cancer and heart disease – it is the dominant feature of decline and mortality in that species.
Intermittent fasting has been shown in a variety of species to have a broadly similarly effect to the more usual form of calorie restriction approaches, at least when the overall intake of calories is still restricted in comparison to a normal diet. However, it also extends life to some degree even when overall intake of calories is not restricted. Rodents on
