You probably don't want to get up from Thanksgiving dinner feelingrounder than the turkey, but you may not want to fret about calories onthis special holiday. So what to do?

Consider taking a walk, a long one.

Ifyou go whole hog eating heaping portions, going back for seconds andenjoying pumpkin, pecan and apple pie with ice cream, and having acouple glasses of wine, you could wind up eating 4,000 calories ormore. That's about 2,000 calories more than many people need in a day.

Toburn off those extra 2,000 calories, a 180-pound person would have towalk briskly (about 3.5 miles an hour on a level surface) for 5 hours ormore, says Heather Mangieri, a spokeswoman for the Academy of Nutritionand Dietetics and a sports nutritionist in Pittsburgh. "Take aflashlight."

Or better yet, try to walk an extra hour a day for the next week, Mangieri says.

The scary thing is even if you watch your portions and choices, the calorie count climbs quickly, she says.

Toshow this, she tallied the calories in some favorite Thanksgivingfoods. She found that a holiday meal with many of the trimmings (turkey,gravy, mashed potatoes, sweet potato casserole, cranberry salad, rolls,pumpkin pie with whipped cream, apple cider and wine) has about 1,610calories and about 40 grams of fat. That's with no heaping portions orseconds.

To burn off most of the calories in that meal, a180-pound person would have to walk briskly for more than four and ahalf hours.

Mangieri advises people to eat slowly, savor theirmeal and stop eating when they're full. "If you do that then you canspend your Thanksgiving counting your blessing rather than yourcalories."
