Effect of caloric restriction on the natural abundances of nitrogen stable isotopes in tissue proteins (Δ15Ntissue protein = δ15Ntissue protein − δ15Ndiet protein, ‰). Results are means ± standard error for rats with ad libitum access to food (AL group, ■, n = 11) or subjected to gradual energy restriction (CR group, □, n = 12). G—gastrocnemius; S—soleus; TA—tibialis anterior; EAT—epididymal adipose tissue; SAT—subcutaneous adipose tissue. p values in the box refer to the main effects and their interaction in the analysis of variance. **, *, and + indicate significant group effects at p < 0.01, p < 0.05, and p < 0.10, respectively, when controlling for the false discovery rate at 10%.
