Linoleic acid intake raises tissue arachidonic acid, increasing prostaglandin production and stimulating pathways implicated in adipogenesis, leading to more fat cells.

“So, this one is titled The Crucial Role of Dietary Omega-6 Polyunsaturated Fats in excess adipose tissue development, relationship to childhood obesity. There's an interesting chart here where they hypothesize mechanisms by which all of this happens, but the takeaway is essentially that downstream products of omega-6 fatty acid metabolism, and we're focusing mostly on linoleic acid here, may affect the differentiation of fat cells when children are growing, leading to greater adiposity later in”
