Effects Of Exercise Training And Chlorogenic Acid Supplementation On Hepatic Lipid Metabolism In Prediabetes Mice

Area of Science:

• Metabolic Health
• Nutritional Science
• Exercise Physiology

Background:

• Prediabetes is a significant risk factor for metabolic syndrome.
• Promoting healthy lifestyles is crucial for prediabetes prevention.
• Hepatic lipid metabolism is a key target for intervention in prediabetes.

Purpose of the Study:

• To investigate the effects of green coffee (GC), chlorogenic acid (CGA), and exercise training (EX) on hepatic lipid metabolism in a mouse model of prediabetes.
• To determine if GC, CGA, or EX can alleviate HFD-induced metabolic dysfunction.
• To assess potential synergistic effects of combined GC/CGA and EX interventions.

Main Methods:

• A high-fat diet (HFD) was used to induce prediabetes in male C57BL/6 mice.
• Mice were divided into control, GC, CGA, EX, GC+EX, and CGA+EX groups for 10 weeks.
• Plasma and liver samples were collected to analyze metabolic parameters and gene expression.

Main Results:

• HFD-induced prediabetes markers (body weight, glucose, insulin, insulin resistance, lipids) were improved by all treatments.
• GC, CGA, and EX reversed adverse changes in hepatic de novo lipogenesis and beta-oxidation molecules.
• Combined GC/CGA and EX showed no synergistic effects; GC and CGA yielded similar results.

Conclusions:

• Regular exercise is an effective non-therapeutic strategy for managing prediabetes.
• Chlorogenic acid (CGA) supplementation can partially mimic the beneficial effects of exercise on prediabetes.
• GC and CGA interventions show promise for improving metabolic health in prediabetes.
