Your right ! It takes a lot to try to stay on program during the holidays.
Some people give off the vibe like your trying to ruin the holiday by being on a diet that you Really don't need to be on right now. And to be truthful I respond to guilt..must have been those early formative years of indoctrination.
Maybe it's a blessing in disguise I am scheduled to work even though there will be a Huge spread of everything I can't eat. Much easier to turn down food at work then food from family.
As much as we deny it when people try to feed us they are sharing/nurturing us.
Think of a mom who puts the baby to breast and it refuses to nurse ..she feels hurt and in a way like she is being rejected.
I'm working on acknowledging their kindness but sharing honestly how it could harm my progress .
