Ugh, I totally get the low-carb, high-fat thing, but should the meat they're consuming really be hot dogs? The vast majority of hot dogs are full of artificial crap - fillers, preservatives, chemicals and "flavourings". Why not natural grain/grass-fed beef or pork? Ya know, REAL meat?
On a random side note, the children's book When You Reach Me by Rebecca Stead deals with an epileptic character and her "special" (ie. ketogenic) diet in a beautiful, sensitive, positive way. Awesome book!
