This was an issue for me when I started my current program last November. During my scheduled 9 a.m. snack of a protein drink, fellow staff in the employee break room were toasting raisin-cinnamon toast or bagels or having hash browns. I just about died until I decided to just breathe in deeply and enjoy the delicious smells, knowing that enjoying the scent doesn't cost me a single calorie.
I've also learned that giving in to this sort of emotionally-driven craving is still a choice. Feeling pleasure or feeling misery over sweet scents is a choice, believe it or not. There was a time I would have never, ever made that statement but I'm learning to think differently about my relationship with food.
