You’ve waited more than a month for that 4-foot-tall, green-clad siren to arrive on your doorstep and satiate your hunger with her boxes of sweet, crunchy goodness.

But now that the neighbor’s child has delivered your order of Girl Scout cookies, the true test of your willpower begins. You must resist the urge to don your bathrobe and slippers, plop down on the couch in front of the television and polish off that box of Thin Mints.

“You shouldn’t eat a whole sleeve at a time,” Dallas nutritionist Robin Plotkin says. “It’s a good idea to take out a few, close the box and put it away.”

While a few cookies won’t do that much damage, you need to consider that extra snack when calculating your daily fat and caloric intake. If you plan to add two Samoas to lunch, you must subtract them from someplace else.

Here are a few ideas about where to cut back:
