While obesity-associated chronic unresolved inflammation contributes to metabolic dysfunctions, acute inflammation supports healthy adipose tissue remodeling and expansion. Platelet-activating factor (PAF), a \u201cprimitive\u201d signaling molecule, is among the key mediators involved in the acute phase of inflammation and in various pathophysiological processes. This article explores the role of PAF in fat accumulation and obesity by reviewing experimental data from cell cultures, animals, and humans. It proposes an emerging biochemical mechanism in an attempt to explain its dual role in the healthy and obese adipose tissue, including also data on PAF\u2019s potential involvement in epigenetic mechanisms that may be linked to the \u201cobesity memory\u201d. Finally, it highlights the potential of natural PAF modulators in promoting functional adipose tissue, thermogenesis, and obesity prevention through a healthy lifestyle, including a Mediterranean diet rich in PAF weak agonists\/PAF receptor antagonists and regular exercise, which help maintain controlled PAF levels. Conversely, in cases of obesity-related systemic inflammation with excessive PAF levels, potent PAF inhibitors like ginkgolide B and rupatadine may help mitigate metabolic dysfunctions with PAFR antagonists potentially enhancing their effects synergistically.<\/jats:p>","DOI":"10.3390\/cells14070471","type":"journal-article","created":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T10:10:08Z","timestamp":1742551808000},"page":"471","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Platelet-Activating Factor-Induced Inflammation in Obesity: A Two-Sided Coin of Protection and Risk"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7071-5920","authenticated-orcid":false,"given":"Smaragdi","family":"Antonopoulou","sequence":"first","affiliation":[{"name":"Department of Nutrition and Dietetics, School of Health Sciences and Education, Harokopio University, 17671 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,21]]},"reference":[{"key":"ref_1","unstructured":"(2025, January 25).
