GLP BRIEF
This week: Why McDonald's is talking about portion sizes, why food measurements can be less precise than you think, what GLP-1s can and can't do for sleep apnea, and the unexpected thing happening to readers' bedtimes.
THE BIG QUESTION
Why Is McDonald’s Suddenly Talking About Portion Sizes?
You used to order the big combo. Now you can't finish half of it.
McDonald's is paying attention. At a recent investor meeting, an executive noted that 84% of U.S. households with someone taking a GLP-1 visit McDonald's. The company is watching to see how those customers' habits change.
The broader market data tells a similar story. Fast-food spending among GLP-1 households drops nearly 9% after 6–8 months on the medication. And when market research firm PwC asked GLP-1 users what they wanted from restaurants, smaller portions and flexible pricing were high on the list:
- About a third wanted smaller meals at lower prices.
- Nearly a third wanted half-portions or split plates without an extra charge.
For decades, restaurant "value" has meant getting more food for your money. But if you're not hungry for a large fry, extra food isn't really a deal—it's just food that may end up in the trash.
Restaurants are starting to notice. Some are looking at smaller portions, more protein-focused options, and more flexible ways to order.
KEY TAKEAWAY: Try this: "Could I get a half portion, or a to-go box up front?" Some restaurants will accommodate you even if it isn't listed on the menu. It never hurts to ask.

Restaurants Are Still Catching Up. You Don't Have to Wait.
Scan appetizers and sides first. Ask for a smaller portion before ordering, or split a meal on purpose.

RESEARCH WATCH
GLP-1s and Sleep Apnea: What They Can—and Can't—Do
What the study found: A recent review of research on GLP-1s and obstructive sleep apnea found that the medications can reduce the number of breathing problems during sleep. But the available evidence does not show that they can replace CPAP.
The numbers: GLP-1s reduced apnea and hypopnea events by about 6 to 22 events per hour. CPAP reduced them by about 31 events per hour.
How it may work: GLP-1s appear to help mainly through weight loss, including reducing fat around the upper airway. CPAP works differently. It uses air pressure to help keep the airway open while you sleep.
THE TAKEAWAY: GLP-1s may become one useful tool for treating sleep apnea, but whether they can replace or reduce other treatments depends on your health and what your doctor recommends.
If you have sleep apnea, keep using your CPAP unless your doctor tells you otherwise.
FROM THE COMMUNITY
"Sleepy"
Someone in the community noticed their bedtime moved—by hours.
They used to stay up late. Now they struggle to make it past 10 p.m. Another reader said they started feeling ready for sleep around 9 p.m.
For some people, the fatigue seems to hit hardest around "shot day." For others, it takes months to settle into a new routine.
None of this proves the medication is the direct cause for any one person. What you eat, how well you sleep, and whether you're getting enough fluids can all affect how you feel, too.
But the pattern comes up often enough to be worth paying attention to.
YOUR ACTION STEP TODAY: For one week, jot down your shot day, bedtime, food intake, and fatigue level. That gives you something concrete to share with your prescribing doctor instead of trying to remember everything later.
A NOTE FROM GLP BRIEF
SPONSORED BY BETTERHELP
When Your Routine Changes, Your Head Has to Adjust Too
GLP-1s can change your daily routine in ways that have nothing to do with the number on a scale.
Maybe you're eating differently, sleeping differently, or handling social situations around food in a whole new way. Getting used to a new routine can take more mental energy than you expect.
Sometimes it helps to have someone outside your usual circle to talk things through with.

WAIT, WHAT?
Your Tablespoon Might Be Lying to You
A reader in the community was weighing food, exercising, tracking calories, and taking their medication, but the scale wasn't moving as expected.
Then they bought a digital kitchen scale.
What they discovered wasn't that their measuring spoons were broken. It was that measuring food by volume isn't always as precise as it seems.
A tablespoon of peanut butter, shredded cheese, or olive oil can weigh very different amounts depending on how tightly it's packed, poured, or heaped.
"I'm tracking everything" and "I'm measuring everything precisely" are two different things.
An eyeballed pour of cooking oil or a packed scoop of nut butter can contain significantly more calories than expected.
COULD YOUR MEASUREMENTS BE OFF?
- You've never checked a measuring spoon or cup against a digital scale.
- You eyeball liquids like oil, salad dressing, or coffee creamer.
- You measure dense foods like peanut butter, brown sugar, or cheese by volume instead of weight.
5-MINUTE WIN
The One-Time Scale Check
Tonight, pick one item you usually measure by volume or eyeball: cooking oil, salad dressing, peanut butter, or creamer.
- Measure out what you normally call a "tablespoon."
- Weigh that amount on a digital kitchen scale in grams.
- Compare the weight with the serving size on the nutrition label.
You'll quickly see whether your usual measurement is close to what you thought—or way off.
YOUR TURN
Nobody warned you about the big stuff.
But what about the weirdly specific stuff?

GLP BRIEF CHEAT SHEET
Save or screenshot this reference guide for your week:
- Study to Remember: A review found GLP-1s reduced sleep apnea events by 6–22 per hour, compared with about 31 per hour for CPAP.
- Key Trend: Fast-food spending among GLP-1 households drops about 9% over 6–8 months, prompting chains to rethink portions and protein options.
- Practical Rule: Ask for a smaller portion or a to-go container before your meal arrives.
- Mistake to Avoid: Relying only on volume measurements for dense or high-calorie foods.
- One Action to Take: Weigh one food you normally measure by volume tonight.
THE BOTTOM LINE
A smaller appetite doesn't just change what's on your plate. It can quietly change restaurant menus, bedtimes, routines—and even the way you measure your food.
Those small changes are easy to overlook. But they're part of what adjusting to a new routine really looks like.
That's why we report on them.
Be well,
