It is reasonable to hypothesize that the mechanisms of hunger might mediate some fraction of the short-term and long-term benefits to health and life span noted to occur as a result of calorie restriction. Which in turn suggests that strategies for the practice of calorie restriction that suppress hunger might be counterproductive. The hormone ghrelin is involved in the response to hunger, and like most proteins it is involved in a range of processes in metabolism. Evolution tends to result in reuse of protein machinery in many mechanisms. Researchers here report on the connection between ghrelin and memory function, which, like many of the interactions between body and brain, is quite indirect.

Ghrelin is …
