Encouraging direction, but not yet definitive.
A 4-week randomized trial in 26 overweight and obese women shows that exercise training alone produces significant reductions in chest and abdominal circumference and favorable shifts in reproductive hormones (increased estradiol, progesterone, and FSH; decreased LH). Adding cinnamon supplementation provided no clinically meaningful additional benefit beyond exercise for abdominal circumference or any reproductive hormone concentration, with only chest circumference showing a statistically significant between-group difference. The study is too small and short to establish cinnamon's role in fertility or metabolic health.
Parallel-group randomized controlled trial. Inactive overweight and obese women; specific age range, BMI thresholds, and other eligibility criteria not detailed.. Intervention: Exercise training three times weekly for 4 weeks combined with cinnamon supplementation three times weekly. Compared with: Exercise training alone three times weekly for 4 weeks. n = 26.
Both groups showed significant pre-to-post reductions in chest and abdominal circumference (all p ≤ 0.005) Estradiol, progesterone, and FSH concentrations increased significantly in both groups (all p ≤ 0.005); LH concentrations decreased significantly (all p ≤ 0.005) Between-group comparison revealed significant difference only for chest circumference (p = 0.003); no significant differences in abdominal circumference or reproductive hormone concentrations (all p > 0.05)

Clinicians should recognize that exercise training alone produces meaningful improvements in anthropometric measures and reproductive hormone profiles in overweight and obese women over 4 weeks. The addition of cinnamon supplementation does not appear to augment these benefits for most outcomes studied, so current evidence does not support recommending it as adjunctive therapy for this indication without larger trials.
A small, well-designed randomized trial showing favorable within-group changes in anthropometric and hormonal measures with exercise, but minimal added benefit from cinnamon supplementation; results are real but from a limited sample requiring confirmation.

Background. The prevalence of obesity and increased fat in the chest and abdomen in women and hormonal changes, can affect female fertility. The present study aims to investigate the effect of exercise training combined with cinnamon supplementation on chest and abdominal circumference, as well as sex hormones, in overweight and obese women.Methods. Twenty-six inactive overweight and obese women were randomly allocated to an exercise (E; n = 13) and exercise plus cinnamon supplementation (E+S; n = 13) group. Both groups completed a 4-week exercise program three times weekly, while the E+S group additionally received cinnamon supplementation three times weekly. Chest and abdominal circumferences and serum concentrations of estradiol, progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were assessed before and after the intervention.Results. Significant pre-to-post reductions in chest and abdominal circumference were observed in both groups (all p ≤ 0.005). Estradiol, progesterone, and FSH concentrations increased, whereas LH concentrations decreased significantly in both groups (all p ≤ 0.005). However, between-group comparisons revealed a significant difference only for chest circumference (p = 0.003), with no significant group differences in abdominal circumference or any reproductive hormone concentration (all p > 0.05).Conclusion. Both groups showed favorable changes in anthropometric and reproductive hormone measures following the 4-week study period. However, the significant between-group difference was limited to chest circumference, providing no clear evidence that cinnamon supplementation conferred additional benefits for abdominal circumference or reproductive hormone profiles beyond those observed with exercise. These findings highlight the potential relevance of exercise-based interventions while warranting confirmation in larger, adequately powered trials.
