Pine nut oil may help reduce food consumption, thereby helping with weight loss, a new study reports.
Researchers from England explained that certain free fatty acids have been shown to have potent effects on food intake and self-reported changes in appetite.
They examined the effects of a Korean pine nut oil product, PinnoThinac, at doses of 2, 4 and 6 grams of triglyceride (TG) and 2 grams of free fatty acid (FFA), on food intake and appetite in 42 overweight female volunteers.
The study found that 2 grams of FFA PinnoThinac, given 30 minutes prior to an ad-libitum buffet test lunch, significantly reduced food intake (gram) by nine percent compared to olive oil control. PinnoThinac did not have a significant effect on macronutrient intake or ratings of appetite were observed.
The researchers suggested that the lack of any effect of the TG form found in this study could be attributed to the timings of the dosing regimen.
The study authors concluded that PinnoThinac may exert satiating effects consistent with its known action on CCK and GLP-1 release and previously observed effects on self-reported appetite ratings.
