McDonald’s is spending $8.5 billion to reinvent itself for the Ozempic era — but investors aren’t loving the price tag

Now, even McDonald’s appears to be reading the room.

The fast-food chain is exploring higher-protein menu options and different portion sizes, as customers increasingly look for meals that will satisfy them without leaving them feeling like they need to unbutton their jeans.

Moneywise reached out to McDonald’s for comment, and the company directed us to remarks from its Investor Day. During the presentation, McDonald’s USA President said customers are looking for “food that leaves them feeling satisfied without feeling like too much.”

The menu rethink is part of a much bigger makeover. McDonald’s plans to spend roughly $8.5 billion to support franchisees over the next decade. The money will go toward modernizing restaurants, improving operations and helping franchisees win customers.

The plan did not impress Wall Street, with shares falling 6% in afternoon trading after the spending was announced.

Shifting fast food orders

Part of that shift comes as Americans are putting more money and attention toward wellness. GLP-1 use is one piece of that change. About 11% of U.S. adults said they were using a GLP-1 medication for weight loss in 2026, up from just 3% in 2024, according to Gallup.

The U.S. wellness economy reached roughly $2.1 trillion in 2024, making it the largest wellness market in the world, according to the Global Wellness Institute.

That focus is increasingly showing up in how some consumers order fast food, too. McDonald’s is placing a sizable bet on getting customers through the doors more often at a time when its rivals are making their own expensive plans.

Burger King, for example, has committed up to $700 million through 2028 to its “Reclaim the Flame” turnaround plan, which includes restaurant remodels, new technology, kitchen equipment and other upgrades. Those efforts appear to be gaining traction as Burger King U.S. reported comparable-sales growth of 8.5% in the second quarter of 2026.

That puts some pressure on McDonald’s to make sure its own investment pays off. The company carried roughly $40 billion in debt at the end of 2025 and returned about $7.1 billion to shareholders through dividends and share buybacks that year.

But the company isn’t writing one enormous check tomorrow. Its planned spending will be spread over the coming decade, giving McDonald’s time to see whether upgraded restaurants, new technology and a changing menu can translate into more visits.

The new fast-food order

All of that spending and menu strategy ultimately comes down to one thing: what people are actually ordering.

TikTok creator @SmallerSam*PCOS recently shared what she described as a lower-calorie McDonald’s order totaling 520 calories and 32 grams of protein.

“I got a three-piece McCrispy strip, just the strips,” she said, adding a kids’ size fries and low-calorie spicy buffalo sauce, along with sweet-and-sour sauce on the side.

The trend points to a broader shift in how consumers are thinking about fast food. Rather than giving it up altogether, many are looking for ways to make familiar orders fit more easily into calorie, protein or portion goals.

For McDonald’s, that changing behavior could represent an opportunity: keeping customers who still want the convenience of the drive-thru but with more flexible menu options.

$15 billion in nuggets

That shift in consumer behavior is also colliding with a very large business opportunity. McDonald’s said chicken is now a nearly $130 billion category growing more than 5% a year. Chicken McNuggets alone account for nearly $15 billion in annual systemwide sales.

Now the company is looking for ways to stretch business even further. It plans to explore more flexibility on the beef side, including different portion sizes and menu options.

“We’re looking to add more choice in beef for those seeking more flexibility in portion sizes, for example, a burger bowl,” Jill McDonald, McDonald’s executive vice president and global chief restaurant experience officer, said during the meeting.
