Majority are quite serious, but after researching in depth the ones I want maybe somewhere among the facts is something I can take and make a joke out of; as someway down the line everyone has or knows someone that's tried out diets but they never last. Saying this I'd like to keep with some serious elements.
I haven't quite decided on how I may present this as of yet, but I was thinking along the lines of having a pictures that morphs into another with a voiceover expressing the letter/word but having it in a motivation voice (really energetic/enthusiastic).
