I work in a bakery so there's temptation all around me! Icing sandwich cakes to when the fresh scones come out of the oven and the girls have one with their coffee but what gets me through is planning. I take a hifi light bar and a piece of fruit for coffee if I've got my own snack and don't feel starving then I can pass on it. Planning my lunches the night before so I always have something to take to work for lunch so im not tempted to just go to the shop for a sandwich!
To be honest I never really picked at the food before BUT I did always have a scone or a piece of tea cake if everyone else was. But as I say, just planning and taking your own stuff in works x
