All this reminds me of Famine's business plan from Good Omens:
"CHOWTM contained spun, plaited, and woven protein molecules, capped and coded, carefully designed to be ignored by even the most ravenous digestive tract enzymes; no-cal sweeteners; mineral oils replacing vegetable oils; fibrous materials, colorings, and flavorings. The end result was a foodstuff almost indistinguishable from any other except for two things. Firstly, the price, which was slightly higher, and secondly, the nutritional content, which was roughly equivalent to that of a Sony Walkman. [...]
MEALSTM was CHOWTM with added sugar and fat. The theory was that if you ate enough MEALSTM you would a) get very fat, and b) die of malnutrition."
