Keep in mind that there are no human studies showing any life extension
advantages for CR and the health effects for both humans and animals seem
very poor on the whole. The non-CR animals seem to rate far superior in
every category but life span e.g. Cognitive function is impaired, puberty is
greatly delayed, menses is skipped. And from my understanding, all of the
animal studies show that the life extension 'benefits' (!) are only attained
with a life long commitment to CR starting in adolecence.
Fagin draws his conclusions from MOUNTAINS of research using human studies
and biochemistry.
What is there to debate?

This seems to contradict Faigin's thesis quite completely.
And as I said, how does catabolic metabolism connect with symptoms of
aging that may be outwardly similar?
