Funny you should mention this! This thread seems to have arrived right on time for me. Today (the 5th) is my birthday, and ever since I started trying to lose weight about 2 weeks ago, it's sort of been hanging over my head because I don't know whether I should "cheat" or not... It IS my birthday, and I can't imagine celebrating without a little cake or something, but then I think about how much progress I've made - and that so far I've had such iron-clad willpower - and it doesn't seem worth it to stop (even just once!) when I've only been going for such a short time... I want to keep the momentum going, you know?
I think the best solution for me will be that I will allow myself to go a little over my usual calories, since it's a special occasion, but I'm not going to waste them on something that I'm not 150% craving. In other words, if I do "cheat," I'll make sure it's with something that I reeeally really want. For example, I'd usually get an ice cream cake to celebrate my birthday, but what I'm really craving right now is a slice of peanut butter cup pie from Baker's Square (my all-time FAVORITE dessert!), so why shouldn't I get that instead? And I'll probably allow myself to have a little chips and salsa, since that is my all-time favorite snack, hehe. But those will probably be my only splurges for the day; other than that I'm planning to stay OP (including getting in some exercise!).
I think "cheat" days can be a good thing for some people, but for myself I really want to limit it to major holidays, i.e. my birthday and Christmas... Maybe Thanksgiving/Easter. For me, it feels good not to have treats like that because I feel really empowered by turning down all of the things that I would have thought nothing of scarfing down before. Since I haven't really told anyone that I'm trying to lose weight, it's like a little mini-victory for me each time I see someone else eating something unhealthy that I'm
not eating. I like to think about all the things I resisted on any given day--not in an obsessive way, but in a "d***, I have amazing willpower!" kind of way.
