Well, it's the same thing with calories. So what if your office had cake for Secretaries Day (excuse me, Administrative Professionals Day)? Why does that single slip-up make you feel it's okay to say "fuck it, I already screwed up" and then eat pizza and cheeseburgers for dinner the rest of the week?
If you look at calories the same way you look at money, I'd bet you would rethink a lot of what you eat.
The general recommendation for us is 2000 calories per day. That is 14,000 calories per week. If you want to lose a pound per week, you need 3500 fewer calories per week, which is only 500 calories per day. Sure, you can starve yourself, or you can create a 500 calorie deficit with diet AND exercise. If you burn 250 calories via daily exercise AND you skip the 16oz Grande Vanilla Latte* from Starbucks, you have successfully created that 500 calorie loss (and probably saved a bunch of money, too!)

On the flip side of this, I want to also say that, if you KNOW there will be a party coming up, or something that you want to eat that is hi-calorie, budget for it! You know that vacation is expensive, so you budget for it. Food is the same way. If I know that on Saturday, we are going out to eat at Cracker Barrel, I plan on eating lighter the entire week and splurging on Saturday. It works both ways, folks.
