Does anyone know whether chewing gum has any adverse effect on your diet. I'm following weight to go and once of the things i find hard is not so much being hungry as the urge to chew on something - usually when i'm working at computer. (PLease don't anyone suggest a bone.) i bought a big pack of strawberry sugar free orbit but it does actually seem to have some calories in it. Is that only if you swallow it? which i wasn't planning to do. i don't want to get tripped up by any sneaky little extras. Any advice please?
