Abstract
Type 2 diabetes is the most serious metabolic, endocrine, and cardiovascular consequence of childhood obesity, which is quickly becoming recognised as a worldwide health crisis. New research has shown that the gut microbiota plays a key role in the development of childhood obesity. This role is mainly manifested when the microbiome ferments fermentable fibre, leading to the production of short-chain fatty acids (SCFA). Acetate, propionate, and butyrate show a wide range of biological activities within this class of metabolites. These include reducing hyperphagia, affecting substrate utilisation, and changing the immunological milieu. The present review synthesizes the prevailing body of evidence that links SCFA production to dietary intervention strategies directed at the amelioration of childhood adiposity. Emphasis is directed toward elucidating the intricate signaling pathways that frame SCFA activity, with particular attention to hypothalamic, enteric, and hepato-pancreatic interligature that modulated energy homeostasis, augmented insulin responsiveness, and curtailed systemic and adipocyte-directed inflammation. Furthermore, the manuscript synthesizes the predominant dietary approaches that enhance SCFA synthesis, systematically appraising their feasibility for incorporation into obesity treatment protocols. The examination focuses on trials that quantify SCFA and associated alterations in metabolic parameters among pediatric cohorts, allowing for the systematic evaluation of both favorable outcomes and the obstacles that impede the transposition of these insights into usual care. The last section outlines potential directions for future study, highlighting the need for dietary treatments tailored to individual gut microbiota compositions to optimise SCFA synthesis and improve ways for monitoring and treating paediatric obesity.
