For decades, American restaurants have operated on the idea that more food equals better value. Now, some of the country's biggest chains are testing the opposite.
Olive Garden is one of them. Its new Lighter Portions section offers smaller versions of favorites including Lasagna Classico, Chicken Parmigiana and Fettuccine Alfredo. And because this is still Olive Garden, the unlimited breadsticks aren't going anywhere.
The seven-item menu rolled out nationwide in January, and the company has said people taking GLP-1 medications were one reason for the change. That group of diners is growing rapidly. Gallup found that 11% of U.S. adults now take a GLP-1 medication for weight loss, up from 3% in 2024.
Their eating habits are changing, too. Research from the University of Arkansas Agricultural Experiment Station found that people taking the medications consume about 700 fewer calories per day.
Fast Food May Feel the Biggest Impact
The biggest change may be happening at the drive-thru.
In a 2026 William Blair survey of 300 GLP-1 users, respondents said their restaurant visits dropped by half after starting the medications, from an average of 9.8 visits per month to 4.9. Quick-service restaurants took the biggest hit.
It isn't hard to see why. Burgers, fried foods and sugary snacks make up a big part of the typical fast-food menu, and those are among the foods GLP-1 users tend to cut back on.
Henry Farr, valuation director at Brand Finance, expects the effects to reach far beyond fast food. He told Food Dive that "millions of everyday consumption decisions could become smaller, less frequent, or shift towards entirely different categories."
A National Restaurant Association survey found that people taking GLP-1 medications purchased a restaurant meal, snack, or beverage 7.6 times during the previous week, compared with 5.1 times for people who weren't taking the drugs. Nearly half said they dine out less often since starting the medication, but one in four said they actually go out more.
So the bigger story may not be whether these diners still go to restaurants. It's what they want when they get there. Smaller portions, more protein, and more vegetables are moving higher on the list.
Restaurants Are Starting to Shrink the Plate
People taking GLP-1s still want to enjoy dinner out. They just may not want a full-size restaurant portion. Until recently, that often meant ordering a regular entree, eating a fraction of it and taking the rest home.
At Olive Garden, diners can now order a smaller Chicken Parmigiana, Lasagna Classico, or Fettuccine Alfredo after 3 p.m. on weekdays or all day on weekends. It's a small change, but one that makes it easier to order according to appetite without making the meal feel like a special dietary event.
P.F. Chang's began offering medium portions in fall 2025, including favorites such as Chang's Spicy Chicken and Mongolian Beef. Some appetizers, including lettuce wraps and dumplings, are available in half portions. For someone with a smaller appetite, half an order of lettuce wraps could easily replace a traditional entree.
The Cheesecake Factory, a restaurant practically famous for plates that could double as serving platters, has also gone smaller with its Bites and Bowls menu. The menu offers smaller dishes such as Korean Fried Cauliflower, Chicken Samosas and Crispy Crab Bites, along with bowls built around ingredients such as chicken, vegetables and rice.
That doesn't mean the giant restaurant entree is disappearing. It means diners are starting to get something they haven't always had, a choice.
Smaller Meals Are Showing Up Everywhere
Sit-down restaurants aren't the only chains adjusting to smaller appetites.
Chipotle introduced its High Protein Menu in December 2025, including options aimed specifically at people looking for GLP-1-friendly meals. Its GLP-1 support page highlights a Low Calorie Bowl and High Fiber Bowl, along with a High Protein Cup of adobo chicken.
Shake Shack has taken a similar approach with its Good Fit menu. The menu includes GLP-1-friendly choices and lets diners swap the traditional bun for a lettuce wrap on several burgers.
Panda Express doesn't have a GLP-1-specific menu, but its regular format already lends itself to smaller meals. A bowl comes with one entree and one side, and choosing Super Greens instead of fried rice is an easy way to add vegetables without ordering something entirely different from everyone else.
Smoothie King has leaned directly into that situation with drinks designed for people taking GLP-1 medications. The Slim-N-Trim GLP-1 Mango Greens has 22 grams of protein, while the Power Meal Slim GLP-1 Vanilla has 19 grams. Both have no added sugar.
How to Order Smaller When You're Traveling
You don't need a special GLP-1 menu to find a smaller meal. In many restaurants, you just have to ask.
Finding a smaller meal can be tricky when you're traveling. Airports, highway stops and resort restaurants aren't exactly known for smaller portions.
Start by asking whether smaller sizes are available. Nine in 10 GLP-1 users surveyed by the National Restaurant Association said restaurants generally offer healthy options, but 89% said restaurants could do a better job of highlighting those choices. Sometimes the option is already there; it just isn't obvious on the menu.
Another option is to order one or two appetizers instead of an entree. If you're traveling, keeping a few high-protein snacks in your bag can also come in handy when your only choices are airport food or whatever you can find at a highway stop.
And don't be surprised if smaller portions become much easier to find.
Nearly half of the GLP-1 users William Blair surveyed said they would visit restaurants more often if smaller portions were available. Among users ages 35 to 44, that number jumped to 65%.
Smaller portions aren't just useful for people taking GLP-1s. They're also good for anyone who wants to try a few dishes, doesn't want leftovers or simply isn't hungry enough for a huge entree. More choices in portion size could make eating out better for everyone.
