I don't want to hurt my reputation as Cynical Sue, so I have to throw out the following:
We've heard about pine nut oil for appetite suppression for a couple of years, but we've yet to hear of anyone actually seeing any benefit. Also, if it really was as good as they say, why isn't it a highly recommended product? So far, most of the recommendations come from those with financial stake in the product.
AND it looks like the only study done involved just 18 subjects, and was conducted by the manufacturer and not an independent organization.
It is recommended to take 3 grams 30 minutes before eating a meal. Subjects reported 29% less hunger (I think that was it, could have been 27). I'm not sure how they come up with a figure like that
One caveat: The vast majority of people do not overeat due to appetite. We surveyed over 10,000 people to find out why they overate. Was it due to true, physical hunger? Or was it due to stress, boredom, or other emotional eating patterns. Only 6% said they ate due to real hunger. Those are going to be the only people that benefit from an appetite suppressant, natural or not.
