Build Your Holiday Eating Strategy Now, Not on December 1st

By Dr. Farhan Abdullah, DO | Medical Director, Magnolia Functional Wellness | Southlake, TX

Picture the Friday after Thanksgiving. Three containers of leftovers are stacked in the fridge, your jeans feel a little different, and a quiet voice says you'll sort it all out on December 1st. Then December 1st arrives with office cookie platters, a holiday party every other night, and a calendar that has no room for the version of you who meticulously meal preps. Sound familiar? I hear some form of it from patients every single November.

I'm Dr. Farhan Abdullah, an internal medicine physician, and at Magnolia Functional Wellness in Southlake I spend a lot of my week talking with people about weight, metabolism, and the stubborn gap between what they know and what they do at 8 p.m. on a Tuesday. After years in the hospital and now in clinic, I've come to believe one thing about the holidays above all. The people who do well aren't the ones with the most willpower in December. They're the ones who made a plan in early November, while their calendar was still calm and their judgment wasn't tired.

Why December 1st Is the Wrong Starting Line

Here's what actually happens on the first of the month. You decide to be good. You're also facing a week of events you haven't thought through, a stack of work deadlines, shorter days that nudge your sleep around, and food that was designed by someone who really wanted you to have seconds. Deciding in the moment, under stress, with a plate in your hand, is the hardest way to make a food choice. Your brain is tired. Your cravings are loud. Everyone around you is eating.

A strategy built ahead of time takes most of those decisions off the table. You already know what you'll do at the Thursday dinner, how you'll handle the neighbor's party, what you'll eat before you go, and what counts as a win. That's the entire idea. You aren't trying to be a saint for six weeks. You're trying to remove the dozen small moments where a good intention usually falls apart.

It also changes how you feel about the season. Most people I see treat the holidays as a test they expect to fail, which sets up a cycle of overeating, guilt, and a drastic reset in January. I'd much rather you walk into Thanksgiving relaxed, enjoy the food you love, and still be recognizable to yourself on January 2nd.

What the Research Says About Holiday Weight

You've probably heard that the average person gains five to ten pounds over the holidays. That number is mostly folklore. When researchers actually measure it, the gain tends to be smaller, and the interesting part is what happens afterward.

A 2026 prospective study in the journal Medicina followed 120 adults through the winter holidays and then a full year later. Body weight rose by roughly a kilogram between the pre-holiday and post-holiday measurements, from about 68.3 to 69.4 kg, and visceral fat area went up too. A year later, those numbers hadn't come back down. Weight sat at 69.45 kg. The researchers concluded that short seasonal periods may contribute to overall annual changes in body weight and fat distribution.

That matches what I see in practice. A pound or two doesn't sound like much, and one holiday season won't undo anyone's health. But if the increase never leaves, and the next season adds another, the math quietly stacks up over a decade. Visceral fat deserves attention in particular, since it's the kind that sits around your organs and tracks closely with metabolic risk.

Now the encouraging side. A 2025 systematic review in Obesity Reviews looked at interventions designed to prevent weight gain during festive and holiday periods. Twelve studies met the inclusion criteria. In the pooled adult data, people who received an intervention gained about one kilogram less than those who didn't, though that result wasn't statistically significant, and the authors rated the certainty of the evidence as very low. They also noted that most of the included studies carried a high risk of bias and came almost entirely from the United States and the United Kingdom.

So what do I take from these two papers? Holiday weight changes are modest but sticky, and simple preventive strategies point in a helpful direction without being proven. I'm not going to oversell a magic protocol, because the evidence for one doesn't exist yet. What the research does support is paying attention early and keeping the changes small, rather than letting them drift.

Build the Plan in Four Moves

Here's the framework I walk patients through. It takes about twenty minutes and it works best if you do it this week.

• Map your calendar. Write down every event between now and New Year's that involves food. Thanksgiving, the office party, the neighborhood gathering, the family dinner. Mark which ones matter to you and which ones you attend out of habit. You don't need a plan for all of them, only for the big ones.
• Pick your two or three non-negotiables. Maybe it's a protein-forward breakfast every morning, a ten-minute walk after your largest meal, or two strength sessions a week. Choose habits small enough to survive a chaotic week. Fancy plans collapse; boring ones hold.
• Decide what you actually want. Not what you think you should want. If your grandmother's pecan pie is the best thing on the table, plan to have a real slice and enjoy it. If store-bought rolls bore you, skip them without a second thought. Spending your indulgences on food you love beats spending them on food that just happens to be nearby.
• Set a trend check, not a daily verdict. Weigh in once a week, same time of day, and look at the direction over a few weeks. A salty dinner can swing the scale two pounds overnight and mean nothing. Four weeks of steady climbing means something.

Protein deserves its own line. Anchor each meal around it, since it keeps you full, protects muscle, and makes the lighter side dishes feel like enough. On a big-meal day, I usually tell people to eat a normal breakfast and a protein-rich lunch rather than starving themselves until the feast. Showing up ravenous is the fastest way to eat past comfortable.

A Little Texas Reality Check

Around here, the holidays have their own rhythm. Thanksgiving means a long afternoon of food with the Cowboys game on in the background, which is a recipe for grazing without noticing. The trick is to give your hands and attention something else. Take a walk at halftime. Eat at the table rather than the couch, if you can. Fill a plate once, sit down, and let the meal have a beginning and an end instead of a slow, four-hour drift of snacks.

Then there's the November weather itself. When the Texas heat finally lets up, it's tempting to hibernate. Resist that a little. A brisk walk around the neighborhood, a lap or two at the park, anything that gets you outside on a nice afternoon counts. Movement doesn't have to be a workout to matter, and it helps with blood sugar, mood, and sleep all at once.

If You're Using a GLP-1 Medication

Some of my patients are on semaglutide or tirzepatide as part of a supervised weight management plan, and the holidays raise a few specific questions for them. The first is that these medications change how much you can comfortably eat. A big, rich meal that you could once finish without a thought may leave you nauseated, bloated, or uncomfortable now. That isn't a failure. It's information. Eat slowly, stop at the first sign of fullness, and start with the protein.

The second is that this is a poor season to change doses on a whim, skip injections to "be safe," or make big adjustments on your own. If you're wondering about your plan going into the holidays, bring it up with your prescriber now, not the week of Christmas. Our guide to physician-supervised GLP-1 weight loss in DFW explains how supervised care is structured, and our semaglutide page covers how that program works at our clinic.

The third is that medication isn't a substitute for the basics. Hydration, protein, resistance training, and sleep still decide how you feel and how much muscle you keep. I'd rather you build those habits now than lean entirely on a prescription.

The Parts Nobody Plans For

Three things sneak up on people, and none of them involve the turkey.

Alcohol comes first. It adds calories without making you feel full, it lowers your guard around food, and it wrecks sleep even when you think it helped you doze off. You don't have to give it up. Decide your limit before the party starts, alternate with water, and eat something substantial first. Deciding at the bar rarely goes well.

Sleep is next. December tends to eat bedtime, and short sleep raises hunger hormones the next day. I've watched patients do everything right with food and still struggle because they were running on five hours a night. If your calendar gets crowded, protect your bedtime first and trim an optional event second.

Finally, there's the leftover trap. Cooking for twelve means eating the same rich food for five days. Pack leftovers for guests to take home, freeze portions you won't get to, and put the leafy and protein items at the front of the fridge. Small changes to what's easy to grab shift what you actually grab.

Start With One Thing This Week

You don't need a perfect December. You're going to eat the stuffing, and you should. What protects your progress is the quiet stuff: steady meals, a few strength sessions, a weekly check on the trend, and a plan for the three or four events that matter most. Pick one habit from the list above and start it this week, while the calendar is still forgiving.

If you'd like help building a plan that fits your health history, your medications, and your actual life, that's the kind of conversation we have every day at Magnolia Functional Wellness in Southlake. It's far easier to adjust in November than to repair in February. You've put in the work to get where you are, so let's make sure the season doesn't take it back.
