  1. aDifference between measurements at 2 or 4 weeks and baseline
  2. bObtained at the time of sacrifice
  3. cTotal food consumed/weight gain during the study period
  4. dp < 0.0001, 2 weeks versus 4 weeks (same group)
  5. ep < 0.001, rapamycin versus control at 2 weeks
  6. fp < 0.0001, rapamycin versus control at 4 weeks
