How to Avoid Overeating on Thanksgiving

To avoid overeating on Thanksgiving, build your first plate from fruits and vegetables and eat those first, per the National Institutes of Health. Use smaller plates, slow down, and give yourself time before seconds, because feeling full can take 15 to 20 minutes. A short walk after dinner helps, too.

How to eat less on Thanksgiving

On Thanksgiving the food arrives all at once, everyone is talking, and nobody is watching the clock. A few small habits help, and none of them involve skipping anything you love.

I have cooked and hosted big family dinners for years, and the plate rarely goes wrong at the first helping. It goes wrong in the long, happy stretch after it, when the dishes keep traveling around the table.

NIH’s News in Health newsletter quotes NIH researchers and an NIH dietitian. It suggests filling at least half your plate with fruits and vegetables and eating those first, so there is less room for the rest. NIH nutritionist Jody Engel adds a line worth keeping on the fridge: “Eat what you love—in moderation.” The CDC says much the same in its holiday health tips. It advises that you allow yourself your favorite foods, stick to smaller servings, and balance them with healthier options.

Here are those habits side by side.

Thanksgiving portion sizes

Nobody publishes an official Thanksgiving portion. The NIDDK, part of NIH, makes one point that helps at a buffet. The serving size on a food label “is not a recommendation of how much you should eat or drink.”

What the NIDDK does suggest is practical. Eat off a plate instead of straight out of the box or bag, and use smaller dishes, bowls and glasses. It also says to take your time chewing and to enjoy the smell and taste of your food. If you cooked too much, its advice is to freeze food you will not serve or eat right away.

Hosts have another easy option. NIH’s News in Health suggests making take-home containers available ahead of time, so guests do not feel they have to eat everything in one sitting. I like that one because it also takes pressure off the cook. NIH obesity and nutrition researcher Susanne Votruba adds a point for hosts: “Everyone is different,” so nobody should be pressured to eat a particular food.

The USDA’s MyPlate Holiday Makeover tips point the same way. It says to brighten up your meals with fruits and vegetables and go easy on the sauces, gravies and cream. If you snack while the turkey cooks, our list of Thanksgiving snacks has easy ideas for the counter.

The cook has a say in the menu as well. NIH’s News in Health suggests cutting sugar in side dishes by leaving off toppings like marshmallows or whipped cream. The USDA suggests flavoring food with herbs and spices instead of sugar and salt. Small swaps like these leave every dish on the table.

How long does it take to feel full

Longer than a first helping lasts. The NIDDK says to slow down so your body can register fullness. It puts the time at “at least 15 minutes.” NIH’s News in Health says it takes about 20 minutes. It adds that eating too quickly can lead you to eat as much as twice what your body needs before your brain gets the message.

So the habit is simple. Finish the first plate, put the fork down and talk for a bit. Then decide on seconds.

NIH’s Engel suggests a glass of water when you feel the urge to splurge. The gap is a good time for it.

The first plate is also the easiest place to practice. Put vegetables and a little of everything you want on it. Sit down and take a few minutes with it. That is the habit the NIDDK describes when it says to focus on what you are eating and chew your food well.

Notice the plate in front of you, too. The first bite of a dish you only make once a year is part of the day. Eating slowly is mostly a way to enjoy those dishes for longer.

What to do after overeating on Thanksgiving

Start by being kind to yourself. One large meal on a holiday is an ordinary part of life. Votruba puts it simply: “Every day is a new day when it comes to eating.” Go back to your usual meals when you are hungry, and let the day be what it was.

Anyone who hosts knows the stretch after the meal: dishes, coffee, pie, couch. A walk fits into it better than people expect, because nobody has to leave the group. NIH’s News in Health suggests a family hike, a neighborhood stroll or a game of flag football between meals, or walking around the house for 5 minutes or more. For more on why a walk after dinner is worth the effort, see our walking guide.

Votruba also says, “Don’t make the holidays be just about food.” Cards, a board game or a walk before pie give the afternoon something to do besides the table. NIH’s Engel adds that you should get the whole family involved.

The CDC says adults need 150 minutes of moderate-intensity activity a week, and you can break it into smaller chunks. It also says some physical activity is better than none. A stroll after dinner counts toward that.

A regular bedtime is part of the day too. The CDC says adults 18 to 60 need 7 or more hours of sleep per day.

Stress is part of many holidays. Our post on stress and eating covers how stress and overeating are linked.

Frequently asked questions about overeating on Thanksgiving

Is it okay to enjoy your favorite foods on Thanksgiving?

Yes. The CDC says to allow yourself to have your favorite foods, stick to smaller servings and balance them with healthier options. NIH nutritionist Jody Engel puts it as “Eat what you love—in moderation.” Neither source asks you to skip a dish.

Should you eat breakfast on Thanksgiving?

NIH’s News in Health lists enjoying a healthy breakfast among its tips to help prevent overeating later on. If you are unsure what suits you, a clinician can help.

Does a glass of water help before seconds?

NIH nutritionist Jody Engel suggests trying a glass of water when you feel the urge to splurge. It also gives you a few minutes, and the NIDDK says fullness can take at least 15 minutes to register. Water will not suit everyone, so follow any advice from your own clinician.

What should you do if overeating on Thanksgiving feels out of control?

The National Institute of Mental Health describes a condition in which people regularly lose control of their eating and eat unusually large amounts of food. It advises that if you have concerns about your eating behavior or mental health, you talk to a primary care provider. NIMH describes a regular pattern, not a single big meal. If that sounds familiar, a primary care provider can point you to help.
