Anyhow. The answer (to any problem, really) is simple: good food, preferably as unhealthy as possible. Please see below for instructions.
Boiled eggs and butter
Liver paté, tomato, pickle and some more butter
Mayo, tomato, cucumber and cured ham
White bread (you can forget the fibre and all the other good stuff)
Add more mayo, shrmps/prawns, fruit & veg. Eat and enjoy!
