Personally, I shouldn't look at food I can't eat but I can see how others might be the opposite. I think there have been studies done where people visual eating yummy things and they eat less at their next meal ... but there are also studies that show that people eat more when after watching junk food commercials. So monitor your hunger ... this could be the best thing for your diet, or the worst!
For me, I am into warming essential oils and those strong flavors are really cutting into my feelings of hunger. Having my kitchen smell like peppermint keeps me feeling festive, but with no urge to buy candy canes.
