From RealAge Food Bites    by Lisa Young, RD

I liked these ideas because they are quick and easy, not difficult.  They don't require a lot of planning

Eat only half a candy bar or energy bar (both pack a lot of calories).
Use 1 tablespoon of salad dressing instead of 2 (toss the salad really well and you won't even notice the difference).
Choose small 1-ounce pitas instead of the larger 2-ounce size.  (Or cut them in half)
Spread 1 tablespoon of peanut butter instead of 2 on bread or crackers.
Leave the last few bites of pasta on your plate.
Use one pat of butter instead of three on a baked potato.
Order a tall cappuccino instead of a grande the next time you visit Starbucks.

More ideas from RealAge
Scramble one egg for yourself, not two. (Or one whole egg and a white)
Make all your sandwiches open-faced -- omit the top slice of bread.
Skip the last three bites of any main course.
Snack on one fist-sized bunch of grapes, not two.  (Make sure that is all you bring with you to resist the temptation - see a recurring theme here?)
Grab five Hershey's dark chocolate Kisses instead of ten.  (I like to measure any snacks out in little containers so I can't keep eating.  That way I still get something but have some left over for the next day!)
Choose a white wine spritzer over a 5-ounce glass of wine.
Have a 6-inch Roast Beef sandwich at Subway instead of a 6-inch Classic Steak & Cheese.
Order a small cup at Dairy Queen instead of a small cone.  (This one wasn't hard for me - I LOVE the ice cream so it allows me to focus on the ice cream).

If anybody has any other easy ways to cut a few calories here and there, please share them for everybody to see.  My favorite motto has become - if you want seconds you can have seconds .... of vegetables!
