Enjoy festive food while keeping routines from slipping for the whole season.
Anchor the days you control
Keep breakfast and lunch steady and protein-rich on non-festival days. That alone stops the season from becoming one long feast.
At the gathering
Eat a meal or protein snack before you go. Choose sweets you enjoy and have them slowly after a meal.
Keep moving
Walk after a big meal; keep strength sessions, even if shorter.
If you have diabetes
Check glucose more often. Consult your doctor before fasting, especially if you use insulin or sulfonylureas that can cause low glucose.
