Always being fed speeds up your aging clock:
- Three meals a day plus bars and snacks in between means some people never feel hunger in their whole lives
- Dogs, mice and monkeys that don't eat all the time live 30% longer and stay healthy
- Clive McKay's rats took in fewer calories in the 1930s and lived 30% longer, then the field ignored it
- Low insulin and low IGF-1 switch on the longevity genes, the sirtuins. High insulin all day leaves SIRT1 off and your epigenome degrades quicker
