	Diet (% Calories from Fat) and Body Mass (in grams)
Experimental Group (age in weeks)	Normal Fat (10%)	High Fat (60%)
Group 1a (30 weeks)	33.5 (±2.7)	52.9 (±4.9)b
Group 2A (30 weeks)	35.6 (±2.4)c	48.8 (±2.6)b,c
Group 2B (52 weeks)	40.8 (±2.5)d	58.2 (±3.2)d,e

^aDoes not include ENU-treated mice for either dietary regimen

^bSignificantly higher body mass than normal-fat diet mice at 30 weeks (p < 0.0001)

^cNot significantly different from mice on respective diets among groups at 30 weeks

^dSignificantly higher body mass than mice on respective diets at 30 weeks (p < 0.0001 for normal fat diet, p < 0.003 for high fat diet)

^eSignificantly higher body mass than normal-fat diet mice at 52 weeks (p < 0.0001)
