A great deal of the time we are bored, not hungry. A certain time of the day will hit and the snack attacks... attack!
If you can pinpoint a time in your day when this is likely to happen, have a manicure set handy. Give yourself a nice long manicure and then polish your nails. If you work it right, this can take up tons of time and you will have prettier hands to show for it, not to mention a slimmer waistline.
