Is calorie constriction considered nutrition? Of course animals will have evolved different food requirements, but it seems like the basic mechanism of responding to a lack of calories should be the same.
- vanderZwan 12y agoIt's not my field, but I would expect it to be. We don't ingest calories, we ingest chemicals that we convert to energy. A term like "calorie constriction" masks the complicated nutrition processes behind this.

- tokenadult 12y agoYou ask a fair question. I think the large difference in body size and considerable difference in "wild" behavior between human beings and mice leaves some room for doubt about whether they share the same responses to fasting. This, of course, is an empirical question, a question the currently reported study is trying to answer in part.
