Serum level of leptin (pg/ml) in the experimental groups. Tomato and broccoli extracts reduced serum level of leptin in the HFD rats at the end of 1 month treatment; C = control; HFD = high fat diet; SD = stop diet; T 200 = tomato extract 200 mg/kg; T 400 = tomato 400 mg/kg; B 200 = broccoli 200 mg/kg; B 400 = broccoli 400 mg/kg; CX = Chromax. Results were expressed as mean ± SEM and analyzed using one-way ANOVA followed by Bonferroni’s post hoc test. * = Significant from control at P < 0.0001, # = Significant from HFD at P < 0.0001, $ = Significant from SD at P < 0.0001, @ == Significant from T 400 at P < 0.001
