Pinolenic acid, a polyunsaturated fatty acid found predominantly in pine nut oil, has been investigated for its effects on fat metabolism. Some scientific studies suggest that pinolenic acid may help improve fat metabolism by influencing satiety hormones such as cholecystokinin (CCK) and glucagon-like peptide-1 (GLP-1), which can reduce appetite and potentially support weight management. Additionally, limited animal and small human studies indicate that pinolenic acid consumption may enhance fatty acid oxidation and reduce lipid accumulation.

However, the evidence is still preliminary. Most human studies have focused on the effects of pine nut oil on appetite suppression rather than direct changes in fat metabolism or long-term weight loss. Mechanistic studies in animals suggest potential metabolic benefits, but there is a lack of large, well-controlled clinical trials to conclusively demonstrate the efficacy of pinolenic acid for improving poor fat metabolism in humans. Therefore, while there is some scientific rationale and early evidence supporting its use, the strength of the evidence is modest, and further research is required to establish its therapeutic role in fat metabolism.
