Aim: Asprosin, a white adipose tissue-derived glucogenic adipokine, and spexin, a satiety-promoting neuropeptide, are dysregulated in obesity, yet their collective modulation by structured exercise and nutritional supplementation remains poorly characterized. This trial investigated the effects of 12 weeks of combined aerobic–resistance training, with and without taurine supplementation, on plasma asprosin, spexin, and body composition in obese men. Methods: Forty-four obese men (BMI ≥ 30 kg/m2) were allocated in a randomized, placebo-controlled, supplement-blinded design to control plus placebo (CON), taurine supplementation alone (SUP; 3 g/day), exercise plus placebo (EX), or exercise plus taurine (EX + SUP; n = 11 per group). The 12-week protocol combined aerobic training at 60% heart rate reserve (Karvonen formula) with progressive resistance training at 60% of one-repetition maximum, with load re-estimated every four weeks. Plasma asprosin and spexin were quantified by ELISA; body fat percentage (BFP) was assessed by bioelectrical impedance analysis. Two-way repeated-measures ANOVA with Bonferroni post hoc correction and Cohen’s d effect size estimation were applied throughout. Results: Significant Group × Time interactions were detected for all five outcomes (all p 0.05). Conclusions: Combined aerobic–resistance training with taurine supplementation produced statistically superior, large-magnitude improvements in adipokine regulation and body composition relative to either modality in isolation, demonstrating greater improvements in the combined intervention group compared with either modality applied independently. Given the per-group sample of n = 11, these findings should be considered preliminary and exploratory; independent replication in larger, adequately powered trials is required before any clinical translation can be considered.
