Abstract
Background and Objective: Obesity and dyslipidemia are public health challenges. This study aimed to determine the dose-dependent effect of a combined herbal extract (turmeric, fenugreek, ginger, green tea, dill) plus resistance training on lipid profiles in middle-aged obese individuals.
Subjects and Methods: In a double-blind randomized controlled trial, 30 obese adults (35–50 years) were assigned to three groups: exercise + high-dose supplement (1500 mg), exercise + low-dose supplement (500 mg), or exercise + placebo. The intervention lasted 8 weeks (3 weekly resistance band sessions plus daily capsules). Fasting blood samples were analyzed.
Results: The reduction in TG and increase in HDL were greater in women compared to men (P < 0.001). The reduction in TG and TC and the increase in HDL in the exercise + high-dose supplement group were significant compared to both the exercise + low-dose supplement and exercise + placebo groups (P < 0.05). LDL decreased significantly in the exercise + high-dose supplement group compared to the exercise + placebo group (P = 0.012), but the difference was not significant compared to the exercise + low-dose supplement group (P > 0.05). No significant differences were observed between the exercise + low-dose supplement and exercise + placebo groups for any of the variables (P > 0.05).
Conclusion: Herbal extract combined with resistance training improves the lipid profile; the 1500 mg dose showed a significant and remarkable improvement. This dose-dependent relationship demonstrates the importance of determining the effective dose in the efficacy of the combined intervention.
