How about a parody of the diet aid Sensa?

Sensa is called by its manufacturers a “tastant”, a powder you sprinkle on food that makes you eat less. Supposedly the substance sends a signal to the brain that stimulates satiety and triggers your “I feel full” sensation and you stop eating sooner than otherwise. Many people say Sensa is a scam and does nothing. It’s made of maltodextrin, tricalcium phosphate, silica, and natural and artificial flavors.
One potential ANS Wacky would be “Nonsensa” - maybe a chubby wacky character with their index finger doing the circle around the ear gesture
