Friends Compare GLP-1 Weight Loss? How to Leave the Scoreboard

When friends compare GLP-1 weight loss, you don't have to play. You can cheer for them, keep your own numbers private and change the topic with one easy line. And if you're quietly wondering why your best friend lost more on the "same shot," clinical trials show that results vary a lot, even among people on the same medicine at the same dose.

This post is about the in-person version: brunch, the office kitchen, the family group hug that turns into a weigh-in. (If your comparison happens mostly on your phone, see our guide to enjoying GLP-1 stories online without comparing.)

Why does comparing GLP-1 weight loss with friends feel so bad?

Picture it. You're at brunch. Your coworker started the same month as you. She says, "I'm down 30! What about you?" You're down 12. Suddenly your eggs taste like homework.

Comparing feels natural. You started around the same time, maybe you even talked each other into calling the doctor. But a pound count is a very small window into a very big picture. It leaves out:

• Which medicine and which dose. "The shot" can mean very different drugs, and doses go up in steps over months.
• How long each person has been on it. Starting "around the same time" can mean six weeks apart, which matters early on.
• Starting point. Ten pounds is a different share of body weight for different people.
• Health conditions and other medicines. Diabetes, thyroid conditions, sleep, stress and many prescriptions can all play a part.
• Life. Night shifts, a new baby, a breakup, a broken ankle.

Same medicine, same dose: do people really get different results?

Yes, and the trial numbers make it very clear.

In STEP 1, a large trial of weekly semaglutide 2.4 mg (a Wegovy maintenance dose) in 1,961 adults without diabetes, people on the medicine lost an average of 14.9% of their body weight over 68 weeks. But look at how that average breaks down:

Weight lost at week 68	Share of people on semaglutide
5% or more	86.4%
10% or more	69.1%
15% or more	50.5%

So about half of the people reached 15%, and about half didn't. Everyone in that group got the same medicine, the same dose and the same lifestyle program.

In SURMOUNT-1, a trial of tirzepatide in 2,539 adults without diabetes, the average loss at 72 weeks was 15.0%, 19.5% and 20.9% on the 5 mg, 10 mg and 15 mg doses. On the 15 mg dose, 57% lost 20% or more of their body weight, which means 43% didn't.

That's the point. Your friend can be at the top of that spread and you can be in the middle, and you can both be responding. Our explainer on average weight loss vs responder rates goes deeper into how to read these two kinds of numbers. If you're worried your result is low, read why some people respond less to GLP-1 medicines and take your questions to your prescriber, not to brunch.

What can I say when a friend asks how much I've lost?

You don't owe anyone a number. Choose a line for how close you are to the person:

• Light: "Honestly, I'm trying not to count out loud. How are you feeling?"
• Warm: "I'm so happy for you! I'm going at my own pace, and I'm good with that."
• Firm: "I keep my numbers between me and my doctor. Tell me about the trip!"
• Funny: "My scale and I are in a private relationship."

If someone asks again, give the same line again with a smile. You're not dodging. You've answered.

What if the comparing comes from family?

Family comparing tends to be louder and more public. Think of the mom who announces at dinner, "Your cousin lost 40 pounds on that stuff, why not you?"

Try:

• "We're different people on different plans. I'm happy for her."
• "I'd love for us to stop ranking bodies at dinner."
• Later, in private: "When you compare me to Jess, I feel like I'm failing at something that's going fine. Can you just ask how I'm doing instead?"

That last one works because it says how you feel and asks for something specific. Most family members compare out of excitement, not cruelty. They just need a new script.

How do I stop comparing myself, even quietly?

Sometimes nobody says anything, and you're the one keeping score. A few ideas:

1. Change what you measure. If pounds make you spiral, look at a slower, broader picture: waist measurements, energy, how stairs feel, blood pressure or A1C if your doctor tracks them. Our guide on tracking GLP-1 progress beyond the scale has a list.
2. Compare you to you. Your three-month trend says far more about you than anyone else's week does. And remember that weight changes day to day, so one weigh-in tells you little.
3. Notice the "but." "I'm happy for her, but..." is where comparison sneaks in. Stop the sentence before the "but."
4. Mute the topic, not the friend. You can love someone and still ask, "Can we talk about anything but weight today?"

If your weight loss really does seem slow, read slow weight loss on GLP-1 and bring your notes to your next appointment. GLPily's weight chart and daily check-in can make that conversation easier, because you'll have your own trend in front of you instead of someone else's number in your head.

How can I support a friend without turning it into a contest?

If you're the one doing well, you can make it easier for others too.

• Ask how they feel, not how much they've lost. "How's your energy?" opens a real conversation.
• Celebrate wins that aren't numbers. "You seem so much happier on hikes" beats "You're catching up to me!"
• Don't share their news. "Guess who's on Mounjaro too" is not your story to tell.
• Avoid tips that are really doses. "Just go up to the next dose" is a call for their prescriber, not for friends.

A simple swap list

Instead of comparing...	Talk about...
Total pounds lost	What feels easier in daily life
Which dose you're on	How the week's going
Who's "ahead"	Plans you can do together, like a walk, a class or a trip
Side effect scores	What helped, and what you'll ask your doctor
Clothing sizes	Outfits you love wearing right now

You can be truly happy for a friend and still stay off the scoreboard. Your timeline isn't a race against hers. It's yours.

Common questions

Why did my friend lose more weight on the same GLP-1?

Trials show results spread widely, even on the same medicine and dose. In STEP 1, about half of the people on semaglutide 2.4 mg lost 15% or more, and about half didn't. Dose, time on treatment, starting weight, health conditions and other medicines all play a role.

Is it OK to not tell friends how much weight I've lost?

Absolutely. Your numbers are private health information. "I keep my numbers between me and my doctor" is a complete answer.

Does losing less than a friend mean my GLP-1 isn't working?

Not necessarily. A friend's result isn't a benchmark for yours. If you're worried, ask your prescriber what counts as a meaningful response for you and bring your own trend over several months.
