The session delves into the critical influence of nutrition during pregnancy and early childhood on long-term health outcomes, particularly the risk of obesity. Discussion centers on the effects of maternal diet, breastfeeding practices, introduction of complementary foods, and the formation of early dietary habits—all shaping metabolic development and future weight trajectories. Emphasis is placed on evidence-based interventions, public health strategies, and community initiatives that support healthy growth and obesity prevention. Attendees will acquire practical knowledge relevant to clinical practice, policy formulation, and nutrition education, with the goal of fostering lasting improvements in population health.
