Thanksgiving is all about good company, good conversation, and, let’s be honest, really good food. If you want to enjoy every bite and still feel your best, and prevent holiday weight gain, we’ve got you covered. Read on for dietitian-approved holiday diet tips to help you savor the season and avoid Thanksgiving weight gain without overdoing it.

Good news first: you don't have to choose between pie and feeling good. Thanksgiving is meant to be enjoyed, gravy and all. With a few easy tweaks, you can savor the feast and still feel like yourself on Monday, and never think about Thanksgiving weight gain.

Here's the thing about holiday weight gain: it rarely comes from one dinner. It sneaks in over the whole, long holiday weekend and beyond. In fact, the average American gains an average of roughly 0.8 pounds (0.37 kg) between the last week in November and the second week in January.

Why not start the holiday season off right? Navigate through Thanksgiving and nail the entire holiday season, working to maintain weight during the holidays and holding onto your health goals.

6 Healthy Thanksgiving tips to stay on track

No need to nail all 6. Pick 2 or 3 that feel doable, and you'll gain a head start on holiday weight.

1. Eat as usual before the Thanksgiving meal

We've all heard the plan: skip breakfast, skip lunch, and "save room" for the big meal. It sounds clever, but it usually backfires. Show up to the table starving, and you'll inhale your first plate of food before anyone's finished saying grace, blowing right past full and straight into nap territory.

Instead, eat like it's a normal day. Start your Thanksgiving day with a breakfast that has some protein and fiber, like eggs on whole-grain toast, Greek yogurt with berries, or oatmeal with nuts. If dinner's not until late afternoon, grab a small snack an hour or two before, such as an apple with peanut butter. A glass of water before you sit down doesn't hurt either. You'll arrive just hungry enough to enjoy every bite, but calm enough to actually taste every one too.

2. Choose the foods you actually want to enjoy

The Thanksgiving table is basically a buffet with a dozen dishes, and somehow we all feel obligated to try a scoop of each one. Those polite little scoops add up, often on foods we eat anytime or don't even care about. So before you grab a plate, "take a lap." Scope out the whole Thanksgiving spread, then go for the dishes that make your heart sing–the ones you wait for all year.

If Grandma's sweet potato casserole is the star of the show, give it a starring role on your plate–no guilt here! Pass on foods like dinner rolls and the store-bought dip you could have anytime. Then, slow down and actually enjoy it all! Notice the flavors, chat between bites, and put your fork down now and then during the meal. Funny thing: a modest helping of something you love eaten mindfully beats a mountain of food eaten on autopilot every time.

3. Build a satisfying plate and pause for a few seconds

Think of your plate like a pie chart (fitting, right?). Fill about half with veggies. Think green beans, roasted Brussels sprouts, salad, glazed carrots, etc. Give a quarter plate to protein, like turkey, ham, or a plant-based entrée. The last quarter goes to the cozy food you chose in tip 2, like stuffing, mashed potatoes, or mac and cheese. The protein and veggies keep you full, so the rich sides feel like a treat rather than the main event.

A few sneaky tricks help, too. A slightly smaller plate makes a normal portion of food look generous. Take one spoon of each side, not a heaping shovelful. And pour the gravy yourself, so your plate isn't swimming in it.

Once that first plate is clean, hit pause for 15 to 20 minutes. Your brain needs a little time to get the "I'm full" memo. Use the break to catch up with your kin, help clear a few dishes, or refill your water. Still hungry after that? Go back for a smaller round of your absolute favorites. And if dessert is your thing, save some room!

4. Be intentional about your drinks and snacks

Some of the sneakiest extras that add pounds and contribute to Thanksgiving weight gain are the drinks. You don't have to skip toasting with the people you love. Just decide ahead of time how many drinks you want, alternate each one with water or sparkling water, and try lighter picks like a wine spritzer or a cranberry-seltzer mocktail.

Then there's grazing–the art of eating an entire meal before the meal–a.k.a. a classic way to gain weight. A cracker with dip here, a handful of nuts there, "just one" cookie while the turkey roasts, and suddenly you've had dinner before 2 p.m.

A few ways to keep the snacking in check

• Plate it. Put your appetizers on a small plate instead of hovering over the bowl, so you can see what you're having.
• Change rooms. People and conversations love to camp out by the cheeseboard. Wander to another room or step outside to chat.
• Keep your hands busy. Hold a glass of water, help in the kitchen, or join the kids' board game or craft table. Busy hands don't nibble.
• Bring something fresh. A veggie tray with hummus or a shrimp platter gives everyone a lighter option and makes you a hero.

5. Make movement part of the Thanksgiving celebration

Let's be honest: Thanksgiving is the Olympics of lounging. We sit while traveling, sit to eat, then sit some more for the football game. Sprinkling some movement into the day helps balance out the feast, supports your weight goals through the holiday, and shakes off that post-dinner food coma.

If you can, get moving early. Lots of towns host a Thanksgiving morning turkey trot for all ages to join, and there's something fun about jogging next to someone dressed as a turkey. Not a runner? A brisk walk, a bike ride, or a quick living-room workout works just as well. After the meal, grab a water bottle and round up the crew for a stroll around the block. Even 15 to 20 minutes of easy walking after eating improves digestion, blood sugar management, and overall health.

Movement doesn't have to feel like a workout. Toss a football in the yard, play tag with the kids, or volunteer for cleanup duty (your host will love you). Keep it going all weekend with at least one fun outing, like a hike, an ice-skating trip, or a stroll through an outdoor holiday market.

6. Plan for leftovers and the rest of the weekend

Hosting? Hand out filled to-go containers like party favors, so you're not left alone with 3 pies! Keep only the leftovers you really love, and freeze extra turkey and sides in single portions for easy meals later.

Creative ways to manage those leftovers

• Toss sliced turkey into a big salad with greens, nuts, and a spoonful of cranberry sauce as dressing.
• Turn the turkey carcass into broth and whip up a veggie-loaded turkey soup.
• Roll turkey and veggies into a whole-wheat wrap or lettuce cups for a quick lunch.
• Stir leftover roasted veggies into an omelet or grain bowl.

As for the pie, treat it like the special treat it is! Cut a real slice, sit down, and enjoy it, instead of "just straightening the edge" every time you walk past.

What if the scale is up the next day? Here’s what the scale can and cannot tell you

So you hop on the scale Friday morning, and it's up 2 or 3 pounds. Deep breath. That gain is not two pounds of fat. To gain a single pound of body fat, you'd need to eat roughly 3,500 calories more than your body burns, on top of everything you'd normally eat that day. Only an epic, all-in Thanksgiving plate (including seconds) earns those kinds of numbers. Plus, you'd have to eat that much at least twice to gain 2 pounds or more.

Mostly, the scale is showing you some temporary houseguests, so to speak. Holiday food tends to be salty, and salt makes your body hang on to extra water. Carb-heavy favorites like stuffing, rolls, mashed potatoes, and pie replenish your muscles' energy stores (glycogen), and every gram of glycogen brings a few grams of water along for the ride. Add in the food still making its way through your system, plus a drink or 2 and a late night, and the number jumps. The good news? These guests usually pack up and leave within a few days once you're back to your normal routine.

How to stay on track during Thanksgiving and the days after

First rule of the day after: you don't owe anybody a "make-up" plan. Skipping meals, crash diets, or a punishing 2-hour workout usually backfires, leaving you hangry, wiped out, and raiding the fridge by 9 p.m. Easing back into your normal routine works so much better for your health.

On Thanksgiving Day: keep it simple: eat normally beforehand, fill half your plate with veggies, enjoy your favorites slowly, sip water between festive drinks, and squeeze in a walk before or after the meal.

The days following, just get back to your baseline:

• Eat breakfast. Settle back into regular, balanced meals with protein, veggies, fruit, and whole grains.
• Drink up (water, that is). It helps flush excess salt and calm the bloat.
• Go big on produce. After all that richness, fresh fruits and veggies feel amazing and keep things moving.
• Ease back into workouts. Pick up your usual routine instead of doubling it, and toss in extra walks when you can.
• Catch up on sleep. Travel and late nights mess with your rhythm, and tired brains crave more snacks.
• Think ahead. Thanksgiving is just the kickoff to party season. Use these same tricks at every gathering, and the holidays become a string of fun moments instead of a six-week free-for-all.
