Two cohorts: 1) control mice fed ad libitum, and 2) test mice subjected to 40% dietary restriction (60% of ad libitum diet). Dietary restriction started at 2-5 mo of age. All mice from both cohorts were weighed and assessed for body composition at 15-17 mo of age. Lifespan data was collected.

Procedures conducted:
• body weight  Restricted diet vs. ad libitum diet.
• NMR  Body mass, fat mass, lean mass. Restricted diet vs. ad libitum diet.
• colony observation  Life span comparison. Restricted diet vs. ad libitum diet.
