In general, it helps to take smaller portions than you're used to. There's obviously enough room for more if you decide you want it. Before deciding, though, try waiting at least 10 minutes. It can take 20 minutes or more to register fullness, but sometimes even that smaller amount of time helps you to think about a choice rather than just mindlessly digging in. Alcohol adds calories, and it often leads to eating more than you need to or had planned for. So, if you sip slowly, drink less overall, fill up with water or seltzer in between, you'll usually eat less too. You'll feel better afterward on both counts. 5 Reasons You're Not Losing Weight
Keeping certain routines in place, to whatever extent possible,will help as well. For example, try not to stop exercising, even if you have to miss an occasional day. Invite others to take a walk with you after a big meal. You can make that a new tradition. Try to get enough sleep, too. For this affects your weight, appetite and stress level, too. Even if your schedule will be disrupted, think ahead of how you can minimize lost sleep time.
In the end, it comes down to this: our typical holiday season gets packed with too much to do, feels stressful, emphasizes unhealthy overeating and drinking, and lasts for weeks. If we care about our eating and weight overall, we face the question of how to focus on what feels good and meaningful while cutting out, or at least reducing, what doesn't. Any improvement in any year helps build for more the next and the next after that. Then, we can start our new year feeling good about how these weeks have gone, and about ourselves.
