treat yourself to a super flattering, FITTED top or jeans....if i am in a social setting and conscious of not bloating up, i don't feel temptation.
Plus, if people are complimenting your outfit and "have you lost weight?" I think you wouldn't reach for that cake, as you tell them about the amazing low carb program you started.
I would DEFINITELY bring a low carb treat to share, whether it is sweet or something like spinach and creamcheese stuffed mushrooms or bacon wrapped asparagus....just something to enjoy and feel like you get to indulge without going off your plan.
