Summary: Dietary fats in percentages of energy intakes, total fat and Polyunsaturated Fats were significantly higher for carriers of the Ala12 allele (p = 0.03 and 0.05, respectively). For PPARG Pro12Ala polymorphism, significant gene-obesity interaction effects on total fat (p = 0.02), saturated fat (p = 0.03) and monounsaturated fat (p = 0.02) intakes were observed. Obese participants carrying the Ala12 allele had significantly higher intakes of total fat (p = 0.002), saturated fat (p = 0.006) and monounsaturated fat (p = 0.004) in grams.
