Science

Ha ha yeah, sometimes I misread the tongue in cheek for irony I guess :-)

Intermittent fasting makes wonders for short lived animals, extending both their lifespan, but, also as important, their health span.

In longer living animals, like humans, it can make a longer health span, mostly if you're overweight or a couch potato. Maybe more, there are studies but they are hard to do and obviously takes a long time for long lived animals. It won't affect a normal lifespan.
