NO
To investigate the effects of cumin intake on body composition, lipid metabolism, and glycation markers in healthy adults compared with placebo, and to explore potential sex differences in these effects.
Others
To compare the effect of 12-week cumin supplementation with placebo on fat mass as the primary outcome and to evaluate its effects on body composition, lipid metabolism, inflammatory markers, and glycation markers. In addition, potential sex differences in the intervention effects will be explored.

Fat mass at the end of the 12-week intervention
Body fat percentage, fat-free mass, skeletal muscle mass, skeletal muscle mass index (SMI), fat mass index (FMI), ECW/TBW ratio, phase angle, handgrip strength, total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, non-HDL cholesterol, HbA1c, glycated albumin, pentosidine, high-sensitivity C-reactive protein (hs-CRP), high-sensitivity interleukin-6 (hs-IL-6), and skin advanced glycation end products (AGEs). Sex differences in the intervention effects (intervention-by-sex interaction) will also be explored.
