so there's this han study 2019 which we'll link to that looked at um 800 female uh mice now this is a pretty elegant experiment right so for the first three months they ran these mice out on a ad libitum diet and then at three months they were split randomized to i believe a 40 yeah calorie restriction versus ad lib they ran that out until 24 months and then each of those groups was further spread split ad-lib versus continued on so you had one group that was everybody's the same until three months one group that spent the rest of their life on dietary restriction one group that spent the rest of their life ad lib and then you had the middle groups 21 months calorie restricted then to ad-lib 21 months ad-lib to then calorie restricted
