The secret's in the sauce, so to speak, and the sauce is known as OEA. In a Jekyll and Hyde way, OEA is both good and bad. On the up side, it sends hunger-curbing messages to the brain to increase feelings of fullness. It can reduce appetite, induce weight loss, and lower blood cholesterol and triglyceride levels. The new news is that OEA also causes memory consolidation. Like magic, OEA transforms short-term memories ("Mmmm ...that was good. Wait, what did I just eat?") into long-term ones ("Remember that chocolate cake we had at that cafe in Paris in 1991? I want some more of that.").Ok, it's not magic. It's science. OEA activates memory-enhancing signals in the amygdala, the part of the brain involved in the consolidation of memories of emotional events, like, say, a divine slice of chocolate cake.
