Holiday parties on a GLP-1: a plan for the office party and the family dinner

Before you go: don't arrive hungry

The 2025 joint nutrition advisory notes that nausea on a GLP-1 often appears after long stretches without eating, and lists becoming overly hungry and eating large meals among the habits to minimise.¹ A party that starts at 7 pm, after a day of meetings and a skipped lunch, sets up exactly that.

• Check what kind of event it is. A sit-down dinner, drinks with canapés and an open house need different plans.
• Have a small protein snack an hour or two before — Greek yoghurt, a cheese stick with crackers, a hard-boiled egg, turkey slices — so the first thing you reach for isn't the bread basket or a drink.
• Bring something you can eat to a potluck: chicken skewers, shrimp cocktail, devilled eggs or a bean salad. Hosts rarely refuse a platter.
• Decide your drinks plan in advance — none, one, or two with water in between — rather than at the bar.

The office party

Office parties tend to start straight after work, run on drinks, and serve food in small, rich bites. A few things make them easier:

• Get a drink you like that isn't alcohol as soon as you arrive. Sparkling water with lime looks like anything else in a glass and stops people offering you one.
• Eat early in the evening, while the food is fresh and before the second round of drinks.
• Pick the protein bites — skewers, shrimp, cheese, eggs — over pastry, fried canapés and chips.
• Leave when you are ready. A work party is not an endurance test, and an early exit is rarely noticed.

You don't need to explain to colleagues why you are eating little or not drinking. "I'm good with this, thanks" is a complete answer, and your health information is yours to share or keep. See telling people you're on a GLP-1 for scripts at work.

The family dinner

Family meals bring a different pressure: food as love, a cook who has worked all day, and relatives who notice what is on your plate. The same principles apply as at Thanksgiving:

• Serve yourself if you can, onto a smaller plate, with the protein first.
• Take tasting portions of the dishes that matter to the cook, and say something specific and kind about them.
• Eat slowly and stop at the first sign of fullness. On a medicine that slows stomach emptying, fullness keeps building after you stop.³⁴
• Save dessert for later in the evening, in a small portion. The advisory includes portion-controlled treats among the habits to encourage.¹
• Suggest a walk after the meal. It gets you out of the room where the food is, and it is easier on reflux than sitting slumped.

At the buffet: where the protein is

On a small appetite, what you eat first matters more than how much. The joint advisory suggests protein-rich foods first in a meal and a daily protein target of 80 to 120 g.¹ At a typical party spread, the protein is concentrated in a few dishes: 3 oz of cooked shrimp has about 20.4 g, while an ounce of potato chips has under 2 g.⁵

A plate built from the top of this table — a few shrimp, a chicken skewer, an egg, a little cheese — adds up to meaningful protein in a handful of bites, which matters when a handful of bites is all you want. Then add whatever else you would enjoy.

Drinks across a long evening

The joint advisory notes that alcohol may worsen nausea and reflux on these medicines and suggests keeping it to a minimum.¹ Party drinks make that harder to judge, because the measure is rarely standard. A US standard drink is about 14 g of pure alcohol — 12 oz of 5% beer, 5 oz of 12% wine or 1.5 oz of 40% spirits — and NIAAA counts just 8 to 10 oz of a malt beverage such as hard seltzer at about 7% alcohol as one drink.⁶ Punch, mulled wine and cocktails can be anything.

• Eat first; have the first drink after some food, not before.
• Alternate each drink with a glass of water or a soft drink.
• Choose drinks you can measure: a bottle of beer or a glass of wine rather than a refilled cup of punch.
• If you take insulin or a sulfonylurea, ask your prescriber about alcohol; the labels already warn of a higher risk of low blood sugar with those medicines.³⁴

See alcohol on a GLP-1 for what the research says.

Food pushers, drink pushers and comments

Holiday hosts and colleagues often mean well, but repeated offers and remarks about your plate or your body are wearing. Weight stigma is common and harmful, according to a 2020 international consensus statement, so it is reasonable to protect yourself from it.⁷ You don't need a reason to decline, and a reason often invites a debate. These work well and can be repeated:

• "I'm good, thanks — this is perfect."
• "I'm pacing myself. It's a long season."
• "Not drinking tonight." (No reason needed.)
• "Everything looks wonderful. I'll come back for more later."
• "Let's not talk about bodies tonight. How was your year?"

Buffet food safety

Buffets and open houses keep food out for hours, and a stomach bug is miserable on any medicine that already upsets the stomach. The USDA's Food Safety and Inspection Service gives these rules:²

• Throw away perishable food left at room temperature for more than 2 hours, or 1 hour above 90 °F.
• Keep hot food at 140 °F or warmer, using chafing dishes, slow cookers or warming trays.
• Keep cold food at 40 °F or below by nesting dishes in bowls of ice, or use small trays and replace them often.
• Refrigerate leftovers within 2 hours and use them within 3 to 4 days.

As a guest you can't check the clock on every dish, but you can favour platters that have just come out of the kitchen.

Pacing the whole season

One party is easy to plan for; six in three weeks is harder. A few habits keep the season manageable:

• Choose the events that matter and go to fewer, or arrive late and leave early at the rest.
• Keep ordinary days ordinary. Regular, small meals at consistent times are on the advisory's list of habits to encourage; skipping meals to "make up" for a party is not.¹
• Plan a gentle day after a late night: small meals every few hours, fluids, and ginger or peppermint tea, which the advisory mentions for nausea.¹
• Keep moving between events. A walk on the morning after a party helps more than you would expect; see walking more on a GLP-1.

When to contact your prescriber

Keeping a record of it

A season of parties is a good time to see your own patterns. In Cafeity, a photo of the plate, a note about what you drank and how you felt the next morning all sit on one timeline next to your doses, so you can tell which events and which foods were followed by a rough day.
