Obesity is a complex health issue. This review explores how leptin and ghrelin, key hormones in appetite regulation, are affected by physical exercise, though results remain unclear due to varied training protocols and genetics.

Area of Science:

  • Endocrinology and Metabolism
  • Physiology

Context:

  • Obesity presents significant health challenges globally.
  • Adipocytes function as endocrine tissues, secreting hormones like leptin.
  • Leptin and ghrelin are crucial peptide hormones regulating energy balance and body weight.

Purpose:

  • To review current knowledge on leptin and ghrelin in body weight regulation.
  • To examine the impact of exercise training on leptin and ghrelin levels.
  • To elucidate the complex relationship between physical activity and these appetite-regulating hormones.

Summary:

  • Physical exercise is a non-pharmacological approach for weight management.
  • The precise effect of exercise on plasma concentrations of leptin and ghrelin is not definitively established.

  • Variations in exercise intensity, duration, frequency, and genetic factors contribute to inconsistent findings across studies.

    • Impact:

    • Highlights the need for standardized exercise protocols in research.
    • Suggests genetic predispositions may influence individual responses to exercise interventions.
    • Informs future research directions in endocrinology and obesity management through exercise.
