How do folk deal with situations where you have to let you diet slip?
For instance, the family meal on Sunday, the missus/mother/girlfriend/sister/daughter spends all morning slaving over the stove, you have guests round (typically extended family) and a big roast is put on.
You cannot really refuse such a meal as it will cause issues, and you are aware that even thinking about refusing it is a sign of getting a little too OCD (obsessive compulsive disorder) about the whole fitness situation.
Or alternatively when you are round a mate's house or are eating at a restaurant?
Little slips here and there could be good for you?
