The CR Society Scientific Summit
Leading researchers of calorie restriction in humans and in nonhuman primates meet CR Society members
Dr. George Roth, a founder and investigator of the NIA study of calorie restriction in nonhuman primates and a member of the CR Society International Scientific Advisory Council asked the Society to support a calorie restriction scientific summit. Recognizing the value to Society members and the public, the Board agreed to host the Summit, immediately following the CR Society’s 8th Conference. Encouraging translation from science to practice, the Summit brought leaders in calorie restriction research from both the human and the nonhuman-primate fields together with CR Society members.

Day 1 of the Summit featured "state of the art" reports from the perspective of each scientist’s lab – followed by questions and answers, moderated by Dr. George Roth.
Day 2 consisted of brainstorming sessions, moderated by Dr. Don Ingram, another of the original primate study founders.
Purposes of the Summit
- To help correct misunderstandings regarding recent nonhuman primate research report
- To integrate ideas and practices of rapidly advancing human calorie restriction studies with nonhuman primate studies
- To help people apply calorie restriction science to their lives.
Summit discussions included consideration of how to define calorie restriction. Some felt that calorie restriction can be characterized by measuring weight loss and other resulting changes in clinical markers. Others suggested that bona fide calorie restriction must activate cell signaling associated with longevity. Dr. Stephen Spindler asked Paul McGlothin to write a paper explaining the latter position.
Addressing misinterpretations of the Wisconsin and NIA nonhuman primate studies, scientists from the two labs are collaborating on a joint paper. Their findings will be issued in a coordinated manner so that the media and the public will be accurately informed.
The CR Society will publish a copy of the abstract and invite comments from the study authors, to be published here.
