More that aspartame fooled no GI ever into thinking its job was done than that it makes you hungrier. The alkaline phosphatase blocking from it is also hampering phosphate metabolism you might've been using to switch gears, including regulating pH and coexistence with gut flora (detoxifying oligosaccharides etc.) Nice anecdotal going (if it was low density tissue; I should joke 'you uploaded your brain, what did you expect.')
