Opinion: I'm a doctor in East L.A. and Beverly Hills. I want to treat obesity the same way in both places
As a diabetes specialist, I’ve treated thousands of patients, some in Beverly Hills and some in East Los Angeles. My Beverly Hills patients live to become healthy 80- and 90-year-olds. I can’t remember when my last patient from this community lost their vision, had an amputation or started dialysis. Almost none have heart attacks or strokes.
But in under-resourced parts of East L.A. I see people every week in their 40s and 50s who have developed life-altering, preventable diabetes complications — blindness, kidney failure, the loss of a limb. These patients rarely live to grow old.
Obesity is one of the drivers of this heartbreaking disparity. Health-conscious Beverly Hills is replete with doctors’ offices, fresh food and gyms. Most residents there can spend what they need to maintain a healthy diet and get help to control diabetes. In East Los Angeles, where for some a home refrigerator can be a luxury, diabetes and obesity afflict thousands of families who depend on fast and processed food to provide the affordable calories they need to survive.
The tale of these two neighborhoods is replicated across the country. Obesity kills 300,000 Americans annually. It is associated with increased risk of more than 200 other diseases, including heart disease, diabetes, cancer and dementia. According to modeling by my colleagues at the USC Schaeffer Institute for Public Policy & Government Service, the average American will soon have obesity. Black and Latino individuals experience higher rates of severe obesity compared to non-Latino white people, translating into higher rates of chronic diseases.
Despite decades of public health efforts, obesity increases. Some recent lifestyle interventions have shown promise; for the most part, however, simply urging people in minority neighborhoods to change their diets has proved ineffective. Although providing resources and education do help, these initiatives are often grant-funded and not routinely available. Lots of proposed solutions that might resonate in wealthier communities, such as recommending “fixed” foods, with reduced sugar, fats and preservatives, just don’t fly in East L.A. Cost and availability of healthy foods are two reasons. So is culture. Where there is food insecurity, familiar food can be a celebration not easily surrendered.
But at least one weight-loss remedy that is enormously popular in Beverly Hills also works across town: medication. New drugs such as Wegovy/Ozempic (semaglutide) and Zepbound/Mounjaro (tirzepatide), if used with proper medical supervision, can often reduce body weight by 15% or more. Several of my patients with severe obesity have lost close to 100 pounds and avoided much more burdensome metabolic surgery.
The drugs come with list prices that can top $1,200 a month, although health insurance companies often negotiate deep discounts. So far Medicare is not helping reduce patient costs because it is barred from paying for weight-loss drugs. But Medicaid, the state/federal program that covers the poor, faces no such constraint. And it has a big price advantage: By law, it automatically gets the biggest discounts negotiated by any payer.
Several states, including California, have added one or more of the obesity drugs to their Medicaid formularies. In Los Angeles County, use is still not widespread as doctors have to secure prior authorizations through Medicaid managed-care organizations and teach patients how to inject themselves at home. But among those patients who are taking the drugs, we are seeing improvements in health.
The balance between the drugs’ prices and their benefits is a fraught debate, mostly centered on what would happen to public and private sector budgets under broadened coverage. The Congressional Budget Office recently concluded that the costs of authorizing coverage in Medicare would exceed the benefits of beneficiaries’ improved health for the next 10 years.
I’m not an economist, but I know that focusing just on government ledgers can be shortsighted. I see firsthand that medications have a big role to play in the treatment of obesity and diabetes. Like many other drugs I have prescribed for other diseases, over time they will become more affordable while reducing the costs of treating associated illnesses. Research at USC Schaeffer projects that Medicare coverage of obesity treatments could generate $4 trillion in social value to Americans over three decades.
Of course we also need to keep pressing for better, broader fresh food access, healthier diets and safe places to exercise around the clinic where I work in East L.A. However, use of these newer medications in any part of town can provide true benefit even if lifestyle changes are harder to implement.
I’m in favor of whatever works for my patients, no matter where they live, as long as preventive healthcare and individualized treatment plans are part of the equation.

Our universe might be chock-full of cosmic wonder, but you can observe only a fraction of astronomical phenomena with the naked eye. Meteor showers, natural fireworks that streak brightly across the night sky, are one of them.
The latest observable meteor shower will be the Lyrids, which has been active since April 14 and is forecast to continue through April 30. The shower reaches its peak April 21 to 22, or Tuesday night into Wednesday morning.
According to NASA, the Lyrids are one of the oldest known meteor showers, and have been enjoyed by stargazers for nearly 3,000 years. Their bright, speedy streaks are caused by the dusty debris from a comet named Thatcher. They appear to spring from the constellation Lyra, which right now can be seen in the eastern sky at night in the Northern Hemisphere.
The moon will be about 27 percent full tonight, appearing as a thick crescent in the sky, according to the American Meteor Society.
To get a hint at when to best watch for the Lyrids, you can use this tool, which relies on data from the Global Meteor Network. It shows fireball activity levels in real time.
And while you gaze at the heavens, keep an eye out for other stray meteors streaking across the night sky. Skywatchers are reporting that the amount of fireballs is double what is usually seen by this point in the year.
Where meteor showers come from
There is a chance you might see a meteor on any given night, but you are most likely to catch one during a shower. Meteor showers are caused by Earth passing through the rubble trailing a comet or asteroid as it swings around the sun. This debris, which can be as small as a grain of sand, leaves behind a glowing stream of light as it burns up in Earth’s atmosphere.
Meteor showers occur around the same time every year and can last for days or weeks. But there is only a small window when each shower is at its peak, which happens when Earth reaches the densest part of the cosmic debris. The peak is the best time to look for a shower. From our point of view on Earth, the meteors will appear to come from the same point in the sky.
The Perseid meteor shower, for example, peaks in mid-August from the constellation Perseus. The Geminids, which occur every December, radiate from the constellation Gemini.
How to watch a meteor shower
Michelle Nichols, the director of public observing at the Adler Planetarium in Chicago, recommends forgoing the use of telescopes or binoculars while watching a meteor shower.
“You just need your eyes and, ideally, a dark sky,” she said.
That’s because meteors can shoot across large swaths of the sky, so observing equipment can limit your field of view.
Some showers are strong enough to produce up to 100 streaks an hour, according to the American Meteor Society, though you probably won’t see that many.
“Almost everybody is under a light-polluted sky,” Ms. Nichols said. “You may think you’re under a dark sky, but in reality, even in a small town, you can have bright lights nearby.”
Planetariums, local astronomy clubs or even maps like this one can help you figure out where to go to escape excessive light. The best conditions for catching a meteor shower are a clear sky with no moon or cloud cover, sometime between midnight and sunrise. (Moonlight affects visibility in the same way as light pollution, washing out fainter sources of light in the sky.) Make sure to give your eyes at least 30 minutes to adjust to seeing in the dark.
Ms. Nichols also recommends wearing layers, even during the summer. “You’re going to be sitting there for quite a while, watching,” she said. “It’s going to get chilly, even in August.”
Bring a cup of cocoa or tea for even more warmth. Then lie back, scan the sky and enjoy the show.
Where weather is least likely to affect your view
Storm systems sweep across the country in early spring, and some will be obscuring skies tonight. But there will still be plenty of areas with clear skies, particularly in parts of the central United States.
“The best spot is going to be in the Upper Midwest,” said Rich Bann, a meteorologist with the Weather Prediction Center.
Minnesota, Wisconsin and Iowa will offer especially good sky-viewing weather and a beach on the Great Lakes could be a nice spot to look up at the stars.
But don’t expect to view the show from Chicago, as Illinois could see some thunderstorms. The weather will be better in the Northern and Central Plains, particularly the eastern Dakotas.
High, wispy clouds are expected over the Ohio and Tennessee Valleys and into parts of the Mid-Atlantic. But, Mr. Bann said, “you may be able to see some shooting stars through thin clouds.”
Clouds will be draped across much of the Southeast and the Northeast, though there could be some clearing in Florida, Georgia, the Carolinas and Virginia. Remember, the meteors could be visible all night long. If you look outside and see clouds, try again later.
Catching the spectacle will be challenging across much of the West, particularly from Washington into Northern California, where a storm system is bringing rain and snow. That system will move east overnight.
There are likely to be some pockets of clear skies at times across southern Nevada, northwest Arizona and southwest Utah, Mr. Bann said.

WASHINGTON — Amid growing national security concerns, the FBI said Tuesday that it has launched a broad investigation in the deaths or disappearances of at least 10 scientists and staff connected to highly sensitive research, including four from the Los Angeles area.
“The FBI is spearheading the effort to look for connections into the missing and deceased scientists. We are working with the Department of Energy, Department of War, and with our state and state and local law enforcement partners to find answers,” the agency said in a statement.
The FBI’s announcement comes after the House Oversight Committee announced that it would investigate reports of the disappearance and deaths of the scientists, sending letters seeking information from the agencies involved in the federal inquiry as well as NASA, which owns the Jet Propulsion Laboratory in La Cañada Flintridge, where three of the missing or dead scientists worked.
“If the reports are accurate, these deaths and disappearances may represent a grave threat to U.S. national security and to U.S. personnel with access to scientific secrets,” Reps. James Comer (R-Ky.), chairman of the committee, and Eric Burlison (R-Mo.) wrote in the letters.
President Trump told reporters last week that he had been briefed on the missing and dead scientists, which he described as “pretty serious stuff.” He said at the time that he expected answers on whether the deaths were connected “in the next week and a half.”
Michael David Hicks, who studied comets and asteroids at JPL, was the first of the scientists who disappeared or died. He died on July 30, 2023, at the age of 59. No cause of death was disclosed.
A year later, JPL physicist Frank Maiwald died at 61, with no cause of death disclosed.
Two other Los Angeles scientists are part of the string of deaths and disappearances.
On June 22, 2025, Monica Jacinto Reza, a materials scientist at JPL, disappeared while on a hike near Mt. Waterman in the San Gabriel Mountains.
On Feb. 16, Caltech astrophysicist Carl Grillmair was fatally shot on the porch of his Llano home. The Los Angeles County Sheriff’s department arrested Freddy Snyder, 29, in connection with the shooting. Snyder had been arrested in December on suspicion of trespassing on Grillmair’s property.
Snyder has been charged with murder.
There is no evidence at this point that the deaths and disappearances, which occurred over a span of four years, are connected.
A spokesperson for NASA, which owns JPL, said in a statement on X that the agency is “coordinating and cooperating with the relevant agencies in relation to the missing scientists.
“At this time, nothing related to NASA indicates a national security threat,” agency spokesperson Bethany Stevens wrote. “The agency is committed to transparency and will provide more information as able.”
Representatives from Caltech, which manages JPL, did not immediately respond to a request for comment.
The sun had barely risen over the Pacific Ocean when a small motorboat carrying a team of Indigenous artisans and Mexican biologists dropped anchor in a rocky cove near Bahías de Huatulco.
Mauro Habacuc Avendaño Luis, one of the craftsmen, was the first to wade to shore. With an agility belying his age, he struck out over the boulders exposed by low tide. Crouching on a slippery ledge pounded by surf, he reached inside a crevice between two rocks. There, lodged among the urchins, was a snail with a knobby gray shell the size of a walnut. The sight might not dazzle tourists who travel here to see humpback whales, but for Mr. Avendaño, 85, these drab little mollusks represent a way of life.
Marine snails in the genus Plicopurpura are sacred to the Mixtec people of Pinotepa de Don Luis, a small town in southwestern Oaxaca. Men like Mr. Avendaño have been sustainably “milking” them for radiant purple dye for at least 1,500 years. The color suffuses Mixtec textiles and spiritual beliefs. Called tixinda, it symbolizes fertility and death, as well as mythic ties between lunar cycles, women and the sea.
The future of these traditions — and the fate of the snails — are uncertain. The mollusks are subject to intense poaching pressure despite federal protections intended to protect them. Fishermen break them (and the other mollusks they eat) open and sell the meat to local restaurants. Tourists who comb the beaches pluck snails off the rocks and toss them aside.
A severe earthquake in 2020 thrust formerly submerged parts of their habitat above sea level, fatally tossing other mollusks in the snail’s food web to the air, and making once inaccessible places more available to poachers.
Decades ago, dense clusters of snails the size of doorknobs were easy to find, according to Mr. Avendaño. “Full of snails,” he said, sweeping a calloused, violet-stained hand across the coves. Now, most of the snails he finds are small, just over an inch, and yield only a few milliliters of dye.
