I think I understand what the creaters were going for. GooDiet is meant to be one of those concepts that takes two (or more) words and splices them together to create a third, previously unknown hybrid. Fugly, fantabulous (coined by Del tha Funky Homosapien), vurp (Tim Allen), and supercalifragilisticexpialidocious (Mary Poppins) are all good examples of hybrid words that have become, to some extent, part of our lexicon. However, GooDiet is different. Clearly, whoever came up with GooDiet was trying to impart to the consumer that the product was both “Good” and useful if you are on a “Diet”. Their splice came out as a Frankenword.
Now, I do think that a diet composed of goo would be an effective diet because no one would want to consume more goo than necessary to function. However, why pay for something that is advertised to be a disgusting product? With so many other options of gel-based squeeze pouches out there (a few include Vaam, Aquarius, and Qoo) I doubt that the Japanese consumer will choose GooDiet as the space-Jello that they will replace their meals with. As for me, I prefer Jello in bite sized squares. Eating Jello through a straw is for people recovering from jaw surgery.
