Dr. Will Lassek, author of Why Women Need Fat, asked Why Are We Eating so Much More Than We Used to? in his Psychology Today column last month. His theory? It’s the high levels of omega 6 from vegetable oils in our diets that act like a consistent drip of THC to our brains:
We are also learning more about how omega fats influence the appetite-regulating cells in the hypothalamus. These cells are rich in receptors for endocannabinoids, our body’s form of the ingredient in marijuana that increases appetite. Because these are made from the active form of omega-6, arachidonic acid, more omega-6 in the diet means more munchy-promoting endocannibinoids.
