When in this state, the usual solution is to phone/visit a take-away, with popular examples including sultans, dixy and big bite.
The foods consumed are certainly not part of a stable diet, such as your usual pizzas and kebabs, however certain cases have been reported to include excessive amounts of big macs and bargain buckets.
