Ah those holiday meals, seems like we have one every time we turn around. No you can't really sit there looking up points for everything, but you cna probably make a good guess. Do you have the complete food guide? In it you will find the points for many favorites like ham, mashed potatoes ect. Plan on filling up on zero point veggies. Think about the foods you enjoy, which do you feel you need to enjoy which can you take or leave? Me I can give or take dessert I like rolls and potatoes. I hate ham. So I know where I want to spend my points.
Plan it. You probably have a good idea as to what will be available. Figure out how many points you have, plan out how many points each of your favorites are, see your self in your mind choosing those foods in reasonable portions, practice how you will politley decline seconds. Look over your WW tools for living if you ahve those, mental rehearsing is very helpful. If you know before hand how you will handle it then you will handle it better. And write it down, you're more likely to stick to it that way.
Don't skip breakfast, choose a low point filling breakfast that has a bit of protein in it so you don't arrive at dinner starving. One big point killer for me is pop, punch and other calorie laden drinks, choose water or plain iced tea save your points for the yummies
It also helps to save your flex points, don't be afraid to use them, ALL of them, that's what they are there for. Toss in a couple workouts to earn some acivity points.
Look over all the food before you put anything in your mouth or on your plate. That way you know what your options are.
Don't be afraid, fit the plan to live your life. You can do it. We might not be able to eat 8 rolls, 2 peices of pie and 12 ounces ham and expect to have a loss that week. We may do well and still have a gain, if our weigh is clos eto SUnday, if we consume more sodium than usual or don't drink enough water...but it will level off and then again we might have a loss.
