Food delivery apps are reshaping the restaurant industry — and how we eat — by inspiring digital-only establishments that don’t need a dining room or waiters.

At 9:30 on most weeknights, Ricky Lopez, the head chef and owner of Top Round Roast Beef in San Francisco, stacks up dozens of hot beef sandwiches and sides of curly fries to serve hungry diners.

He also breads chicken cutlets for another of his restaurants, Red Ribbon Fried Chicken. He flips beef patties on the grill for a third, TR Burgers and Wings. And he mixes frozen custard for a dessert shop he runs, Ice Cream Custard.

Of Mr. Lopez’s four operations, three are “virtual restaurants” with no physical storefronts, tables or chairs. They exist only inside a mobile app, Uber Eats, the on-demand meal delivery service owned by Uber.

“Delivery used to be maybe a quarter of my business,” Mr. Lopez, 26, said from behind Top Round’s counter, as his staff assembled roast beef and chicken sandwiches and placed them in white paper bags for Uber Eats drivers to deliver. “Now it’s about 75 percent of it.”

Food delivery apps like Uber Eats, DoorDash and Grubhub are starting to reshape the $863 billion American restaurant industry. As more people order food to eat at home, and as delivery becomes faster and more convenient, the apps are changing the very essence of what it means to operate a restaurant.

No longer must restaurateurs rent space for a dining room. All they need is a kitchen — or even just part of one. Then they can hang a shingle inside a meal-delivery app and market their food to the app’s customers, without the hassle and expense of hiring waiters or paying for furniture and tablecloths. Diners who order from the apps may have no idea that the restaurant doesn’t physically exist.

The shift has popularized two types of digital culinary establishments. One is “virtual restaurants,” which are attached to real-life restaurants like Mr. Lopez’s Top Round but make different cuisines specifically for the delivery apps. The other is “ghost kitchens,” which have no retail presence and essentially serve as a meal preparation hub for delivery orders.

“Online ordering is not a necessary evil. It’s the most exciting opportunity in the restaurant industry today,” said Alex Canter, who runs Canter’s Deli in Los Angeles and a start-up that helps restaurants streamline delivery app orders onto one device. “If you don’t use delivery apps, you don’t exist.”

Many of the delivery-only operations are nascent, but their effect may be far-reaching, potentially accelerating people’s turn toward order-in food over restaurant visits and preparing home-cooked meals.

Uber and other companies are driving the change. Since 2017, the ride-hailing company has helped start 4,000 virtual restaurants with restaurateurs like Mr. Lopez, which are exclusive to its Uber Eats app.

Janelle Sallenave, who leads Uber Eats in North America, said the company analyzes neighborhood sales data to identify unmet demand for particular cuisines. Then it approaches restaurants that use the app and encourages them to create a virtual restaurant to meet that demand.

Other companies are also jumping in. Travis Kalanick, the former Uber chief executive, has formed CloudKitchens, a start-up that incubates ghost kitchens.

Yet even as delivery apps create new kinds of restaurants, they are hurting some traditional establishments, which already contend with high operating expenses and brutal competition. Restaurants that use delivery apps like Uber Eats and Grubhub pay commissions of 15 percent to as much as 30 percent on every order. While digital establishments save on overhead, small independent eateries with narrow profit margins can ill afford those fees.

“There’s a concern that it could be a system where restaurant owners are trapped in an unstable, unsuitable business model,” Mark Gjonaj, the chairman of the New York City Council’s small-business committee, said at a four-hour hearing on third-party food delivery in June.

Delivery apps may also undermine the connection between diner and chef. “A chef can occasionally walk out of the dining room and observe a diner enjoying his or her food,” said Shawn Quaid, a chef who oversaw a ghost kitchen in Chicago. Delivery-only facilities “take away the emotional connection and the creative redemption.”

Uber and other delivery apps maintain that they are helping restaurants, not hurting them.

“We exist for demand generation,” said Ms. Sallenave. “Why would a restaurant be working with us if we weren’t helping them increase their orders?”

Delivery-only establishments in the United States date to at least 2013, when a start-up, the Green Summit Group, began work on a ghost kitchen in New York. With Grubhub’s backing, Green Summit produced food that was marketed online under brand names like Leafage (salads) and Butcher Block (sandwiches).

But Green Summit burned through hundreds of thousands of dollars a month, said Jason Shapiro, a consultant who worked for the company. Two years ago, it shut down when it couldn’t attract new investors, he said.

In Europe, the food-delivery app Deliveroo also started testing ghost kitchens. It erected metal kitchen structures called Rooboxes in some unlikely locations, including a derelict parking lot in East London. Last year, Deliveroo opened a ghost kitchen in a warehouse in Paris, where Uber Eats has also tried delivery-only kitchens.

Ghost kitchens have also emerged in China, where online food delivery apps are widely used in the country’s densely populated megacities. China’s food delivery industry hit $70 billion in orders last year, according to iResearch, an analysis firm. One Chinese ghost kitchen start-up, Panda Selected, recently raised $50 million from investors including Tiger Global Management, according to Crunchbase.

Those experiments have spread. Over the last two years, Family Style, a food start-up in Los Angeles, has opened ghost kitchens in three states. It has created more than half a dozen pizza brands with names like Lorenzo’s of New York, Froman’s Chicago Pizza and Gabriella’s New York Pizza, which can be found on Uber Eats and other apps.

CloudKitchens, which Mr. Kalanick founded after leaving Uber in 2017, has leased kitchen space to several established restaurants in Los Angeles, including the farm-to-table chain Sweetgreen, to try the delivery-only model. The Los Angeles facility is one of several ghost kitchens used by Sweetgreen, whose chief executive, Jonathan Neman, has spoken enthusiastically about them.

And Kitchen United, a ghost-kitchen company in Pasadena, Calif., is working with brick-and-mortar restaurants to set up delivery-only establishments. It aims to establish 400 such “kitchen centers” across the country over the next few years.

When it comes types of food, “consumers don’t appear to be saying they’re looking for additional options,” said Jim Collins, Kitchen United’s chief executive. “They appear to be looking for new modes of consumption.”

For Paul Geffner, the growing popularity of food-delivery apps has hurt. He has run Escape From New York Pizza, a small restaurant chain in the Bay Area, for three decades, relying on delivery orders as a major source of revenue.

After he offered delivery through the apps in 2016, his business teetered. Two of his five pizzerias, which together had generated annual profits of $50,000 to $100,000, lost as much as $40,000 a year as customers who had ordered directly from Escape From New York switched to the apps. That forced Mr. Geffner to pay the commissions.

“We saw a direct correlation between the delivery services and the reduction of our income,” Mr. Geffner said. “It was like death by a thousand cuts.”

In May, he closed the two locations. Later that month, one was replaced with a kitchen that mostly does delivery.

Mr. Lopez opened Top Round, a franchise that originated in Los Angeles, in 2017 in San Francisco’s Mission neighborhood. For the first eight months, he said, he lost tens of thousands of dollars.

Last year, Uber approached Mr. Lopez and told him there was demand for late-night orders of burgers and ice cream in his area. Uber, which does not provide financial help to virtual restaurants, has claimed that the digital operations increase sales for restaurateurs by an average of more than 50 percent.

Now he uses Top Round’s kitchen to serve hundreds of new customers across San Francisco. Though he wouldn’t disclose financial information, Mr. Lopez said he had hired another employee to handle the influx of delivery orders. Those orders have stabilized the restaurant’s income so that he no longer works 110-hour weeks just to keep the business afloat.

“We used to close at 9 p.m., but demand has pushed us to stay open later — we close at 2 a.m. now,” Mr. Lopez said. “Most of the night, the kitchen is banging.”

How do you persuade a population to have more babies after generations of limiting families to just one?

A decade after ending China's longtime one-child policy, authorities are pushing a range of ideas and policies to try and encourage more births — tactics that range from cash subsidies to taxing condoms to eliminating a tax on matchmakers and day care centers.

The efforts haven't paid off yet. At least, that's what population figures released Monday show for what is now the world's second-most populous nation. China's population of 1.4 billion continued to shrink, marking the fourth straight year of decrease, new government statistics show. The total population in 2025 stood at 1.404 billion, which was 3 million less than the previous year.

Measured another way, the birth rate in 2025 is the lowest on record since 1949, the year that Mao Zedong’s Communists overthrew the Nationalists and began running China. Figures before that, under the previous Nationalist government, were not available. The rate of 5.63% is the number of births per 1,000 people.

China was long the world’s most populous nation until 2023, when it was surpassed by regional neighbor and sometime rival India. Monday's statistics illustrate the stark demographic pressures faced by the country as it tries to pivot from a problem it is working hard to overcome: status as a nation with a growing but transitional economy that, as is often said, is “getting old before it gets rich.”

Is a snake involved? The number of new babies born was just 7.92 million in 2025, a decline of 1.62 million, or 17%. The latest birth numbers show that the slight tick upwards in 2024 was not a lasting trend. Births declined for seven years in a row through 2023.

Most families cite the costs and pressure of raising a child in a highly competitive society as significant hurdles that now loom larger in the face of an economic downturn that has impacted households struggling to meet their living costs. Another potential factor in the numbers: last year in China was the year of the snake, considered one of the least favored years for having a child under the Chinese zodiac.

Like many other countries in Asia, China has faced a declining fertility rate, or the average number of babies a woman is expected to have in her lifetime. While the government does not regularly publish a fertility rate, last saying it was 1.3 in 2020, experts have estimated it is now around 1. Both figures are far below the 2.1 rate that would maintain the size of China's population.

For decades, the Chinese government barred people from having more than one baby and often sanctioned those who did — a policy that produced more than two generations of only children. In 2015, the government raised the permitted amount of offspring to two and then, facing demographic pressure, further revised the limit to three kids in 2021.

The push for more births is about the economy. China now has 323 million people over 60, or 23% of the entire population. That number has continued to rise, while the working-age population is shrinking, meaning there are fewer workers to support the older population.

This demographic shift is happening while China is in the process of trying to transition away from labor-intensive industries like farming and manufacturing into a consumer-driven economy built with high-tech manufacturing. The difficulty is in trying to get richer as a country, while this population shift likely means a slowing economy.

Officials have had limited success with policy changes to incentivize families to have more children. In July, the government announced cash subsidies of 3,600 yuan ($500) per child to families.

UK, France Mull Social Media Bans for Youth as Debate Rages

Countries including France and Britain are considering following Australia's lead by banning children and some teenagers from using social media, but experts are still locked in a debate over the effectiveness of the move.

Supporters of a ban warn that action needs to be taken to tackle deteriorating mental health among young people, but others say the evidence is inconclusive and want a more nuanced approach.

Australia last month became the first nation to prohibit people under-16s from using immensely popular and profitable social media platforms such as Instagram, Facebook, Tiktok and YouTube.

France is currently debating bills for a similar ban for under-15s, including one championed by President Emmanuel Macron.

The Guardian reported last week that Jonathan Haidt, an American psychologist and supporter of the Australian ban, had been asked to speak to UK government officials.

Haidt argued in his bestselling 2024 book "The Anxious Generation" that too much time looking at screens -- particularly social media -- was rewiring children's brains and "causing an epidemic of mental illness".

While influential among politicians, the book has proven controversial in academic circles.

Canadian psychologist Candice Odgers wrote in a review of the book that the "scary story" Haidt was telling was "not supported by science".

One of the main areas of disagreement has been determining exactly how much effect using social media has on young people's mental health.

Michael Noetel, a researcher at the University of Queensland in Australia, told AFP that "small effects across billions of users add up".

There is "plenty of evidence" that social media does harm to teens, he said, adding that some were demanding an unrealistic level of proof.

"My read is that Haidt is more right than his harshest critics admit, and less right than his book implies," Noetel said.

Given the potential benefit of a ban, he considered it "a bet worth making".

After reviewing the evidence, France's public health watchdog ANSES ruled last week that social media had numerous detrimental effects for adolescents -- particularly girls -- while not being the sole reason for their declining mental health.

Everything in moderation?

Noetel led research published in Psychological Bulletin last year that reviewed more than 100 studies worldwide on the links between screens and the psychological and emotional problems suffered by children and adolescents.

The findings suggested a vicious cycle.

Excessive screen time -- particularly using social media and playing video games -- was associated with problems. This distress then drove youngsters to look at their screens even more.

However, other researchers are wary of a blanket ban.

Ben Singh from the University of Adelaide tracked more than 100,000 young Australians over three years for a study published in JAMA Pediatrics.

The study found that the young people with the worst wellbeing were those who used social media heavily -- more than two hours a day -- or not at all. It was teens who used social networks moderately that fared the best.

"The findings suggest that both excessive restriction and excessive use can be problematic," Singh told AFP.

Again, girls suffered the most from excessive use. Being entirely deprived of social media was found to be most detrimental for boys in their later teens.

'Appallingly toxic'

French psychiatrist Serge Tisseron is among those who have long warned about the huge threat that screens pose to health.

"Social media is appallingly toxic," he told AFP.

But he feared a ban would easily be overcome by tech-savvy teens, at the same time absolving parents of responsibility.

"In recent years, the debate has become extremely polarized between an outright ban or nothing at all," he said, calling for regulation that walks a finer line.

Another option could be to wait and see how the Australian experiment pans out.

"Within a year, we should know much more about how effective the Australian social media ban has been and whether it led to any unintended consequences," Cambridge University researcher Amy Orben said.

Last week, Australia's online safety watchdog said that tech companies have already blocked 4.7 million accounts for under 16s.

Innovative Drug Lowers Triglycerides, Other Blood Lipids

A study led by researchers from the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, revealed a new liver- and gut-targeted oral drug that can safely lower triglycerides and other blood lipids.

Researchers of the study, published last Friday in Nature Medicine, said the innovative drug could represent a breakthrough in treating metabolic diseases related to high triglycerides in the body.

The study said that when we eat, our bodies convert extra calories, especially from carbs, sugar, fats, and alcohol, into molecules called “triglycerides.”

Triglycerides are a form of fat or “lipid,” which the body stores away into its fat cells as an energy fuel for energy between meals.

But, excess amounts of fat in the body can be dangerous, causing a condition known as “hypertriglyceridemia” (“excess triglycerides in the blood”), which significantly increases the risk of heart disease, stroke, and pancreatitis.

This is why we are universally advised to make healthy lifestyle choices in diet, exercise, while particularly bad cases require medication.

The study also found that keeping blood fats in check depends on a careful balance.

It said the liver and intestine release fat particles into the bloodstream, while enzymes work to break them down and clear them away.

When fat production outpaces clearance, triglycerides build up, setting the stage for metabolic diseases like dyslipidemia, acute pancreatitis, and metabolic dysfunction-associated steatotic liver disease (MASLD).

One of the master switches in this system is a protein called Liver X Receptor, or LXR, which controls several genes that are involved in making and handling fats.

When LXR is active, triglycerides and cholesterol tend to rise.

Therefore, dialing it down through medication seems promising, but as LXR is also involved in protective cholesterol pathways elsewhere in the body, blocking it everywhere could do more harm than good.

Now, scientists have addressed this problem with an orally administered compound that can repress the activity of LXR specifically in the liver and gut to lower triglycerides without disrupting the body’s protective cholesterol pathways.

The compound, TLC‑2716, is what is known as an “inverse agonist” for the LXR. Unlike a “blocker” (“antagonist”) that merely stops a receptor from being activated, an “inverse agonist” makes the receptor signal the opposite effect to what it would normally do.

Clinical Trial

The lab findings set the stage for a randomized, placebo-controlled Phase 1 study in healthy adults. Participants received TLC‑2716 for 14 days given as a single dose per day and the trial focused first on safety and tolerability, and the authors report that the drug met these primary endpoints.

But even this short trial had clear effects: participants who received higher doses of TLC‑2716 showed notable drops in triglycerides as well as remnant cholesterol.

At the highest doses of TLC‑2716 (12mg), triglycerides fell by up to 38.5%, while postprandial (“after eating”) remnant cholesterol dropped by as much as 61%.

This happened despite participants starting with relatively normal lipid levels and without the use of other lipid-lowering drugs, the study showed.

Also, the treatment sped up triglyceride clearance by reducing the activity of two proteins that normally slow it down, ApoC3 and ANGPTL3.

At the same time, the study did not detect reductions in blood-cell expression of ABCA1 and ABCG1, genes used here as markers linked to reverse cholesterol transport.

Researchers said larger trials will be needed, but, for now, the concept has its first human proof of principle.
