Appetite craving for food is a constant and powerful stimulator of the gastric glands.
From the described experiment it is clear that the mere act of eating the food even not reaching the stomach determines the stimulation of the gastric glands.
Lifestyle change and changes in diet work faster better and more cheaply than any medication and are as effective or more effective than gastric bypass without any side effects or long-term complications.
I feel an obligation to set the record straight. Actors that say they're affected by something that it changes their life that they take it home with them they're just trying to get nominated for an Oscar!
