It adds up

Over the space of a year the smallest nutritional indiscretions can add up and lead to a small gradual increase in weigh and waistline.  Just one slice of sponge cake a week will add up to the equivalent of 2.5kg of fat or nearly 20,000 calories in a year.  Which means you would only have to walk about 200 miles to burn it off, which is equivalent of walking from St Peter Port to Paris. Over 10 years a weekly cake would provide enough energy to walk to Cairo.  If you don’t fancy wither of these expeditions but still want your cake and eat it, do a little bit every day.  About 900m a day would burn off the cake or a walk from the main road, past the model yacht pond, past castle cornet, out to the light house and back every other day.  If you do this, and do not have your cake and eat it you will lose the 2.5kg a year.
