Rise of weight-loss pills could drive down the cost of airplane tickets
NEWYou can now listen to Fox News articles!
Airfare could become cheaper due to people slimming down, a new theory suggests.
Analysts at Jeffries are predicting that the expanded use of GLP-1 obesity drugs may reduce fuel consumption, which could translate into lower costs for airplane tickets, as Fox Business has reported.
The Wall Street firm suggested that a 10% reduction in average passenger weight could lead to about a 2% savings in aircraft weight, 1.5% lower fuel costs and a 4% boost to earnings per share.

“A slimmer society = lower fuel consumption,” Jeffries reportedly wrote in a note to clients. “Airlines have a history of being vigilant around aircraft weight savings, from olives (pitless, of course) to paper stock.”
These predictions come as weight-loss drug options are growing and the first GLP-1 pill has hit the market, making the medication more accessible.

Gary Leff, a Texas-based travel industry expert and author of the blog “View From the Wing,” elaborated on this prediction in an interview with Fox News Digital.
“The heavier something is, the more fuel it burns,” he said. “If passengers weigh less, planes require less fuel to fly. If everyone went to the bathroom before they flew, they’d weigh less and burn less fuel, too.”

“So, if average passenger weight declines, then flying the same plane on the same route will cost the airline less to operate,” he went on. “And in the most contestable markets, that will bring down fares, too, as airlines compete for passengers.”
Leff suggested that this won’t be true in all markets. Where the “supply of flights is constrained,” like in major cities, these lower costs are more likely to benefit the airlines than the passengers, as “costs fall, but fares do not.”

From a clinical perspective, Dr. Krishna Vyas, a plastic surgeon in New York City, noted that under current conditions, the use of GLP-1 medications is “too limited, too uneven and too short-lived to meaningfully lower average passenger weight at a population level.”

“Most patients discontinue therapy within one to two years, and weight regain after stopping treatment is common, making durable, large-scale reductions in passenger mass unlikely,” he told Fox News Digital. “Even if modest fuel savings were realized, there is no evidence they would translate into lower ticket prices.”

“GLP-1 medications represent a significant medical advance for individual cardiometabolic health, but extending their benefits to speculative effects on airline economics goes beyond what current clinical and population data support,” Vyas continued.
“Until broader access, durable adherence and sustained population-level outcomes are demonstrated, cheaper airfare should be viewed as a theoretical possibility — not a predictable consequence — of weight-loss drug use.”

Dr. Peter Balazs, a hormone and weight loss specialist in New York and New Jersey, discussed how GLP-1s could potentially impact the in-flight experience.
“Patients on GLP-1s experience reduced cravings for carbohydrates and a heightened preference for protein and fats,” he said. “Airlines may need to reconsider in-flight menus to cater to this growing demographic, offering more high-protein, low-carb options.”

Balazs noted that weight-loss medications can lead to gastrointestinal side effects, including GERD, dyspepsia, nausea and vomiting.

“From a medical standpoint, I would suggest loading up on antiemetics (medications that prevent or relieve nausea and vomiting),” Balazs shared as advice to the airlines. “Furthermore, I would counsel patients not to initiate therapy or administer a first dose shortly before a flight to avoid severe side effects at altitude.”

A former Ironman triathlete was stunned to learn that his vision problems were actually the first sign of stage 4 lung cancer.
Dave Nitsche, 57, was initially given just 12 to 24 months to live – but a newly approved drug has helped him surpass that timeframe by several years.
“In 2019, I noticed that I was having trouble seeing with my left eye,” the Canadian man shared during an interview with Fox News Digital. “I went to the optometrist, and they said it was probably a detached retina.”
DOCTOR AND CANCER SURVIVOR GEARS UP TO RUN 7 MARATHONS ON 7 CONTINENTS IN 7 DAYS
After scans revealed fluid buildup and rising pressure, doctors determined that Nitsche had lost vision in the eye — and ultimately removed it. A biopsy of the fluid revealed that it was cancerous.
Next, Nitsche saw more specialists, who extracted fluid from his lungs for more testing. “The next day, the oncologist told me that I had stage 4 lung cancer,” he said.

Nitsche said his doctors were “very shocked” to find that his initial eye issues had stemmed from lung cancer – particularly because he had never been a smoker.
Azam J. Farooqui, M.D., a hematology and oncology physician at Ironwood Cancer & Research Centers in Chandler, Arizona, agreed that Nitsche’s case was “very surprising.”
LUNG CANCER RISING AMONG NON-SMOKERS — HERE’S WHY
“Cancer can find its way to some very odd locations, but the eye is a very, very rare one,” Farooqui, who did not treat Nitsche, told Fox News Digital. “Usually cancer will get there via a nerve channel or blood vessel, but it’s very uncommon.”
Nitsche, an ex-triathlete who has done multiple Ironman races, hadn’t experienced any other symptoms other than the eye issues. “I was running quite a bit at the time,” he shared. “I had a little bit of back pain here and there, but lung cancer definitely wasn’t on my radar.”

His first treatment was a targeted therapy called afatinib, which lasted about three months. When doctors found that the cancer had spread to Nitsche’s brain, he began taking another medication called Tagrisso (osimertinib), which crosses the blood-brain barrier.
HIDDEN FACTOR IN CANCER TREATMENT TIMING MAY AFFECT SURVIVAL, RESEARCHERS SAY
After six years, when those drugs stopped working, Nitsche started taking Rybrevant (amivantamab), a chemo-free drug that he receives via IV infusion every three weeks in a supervised medical setting. After a year on the drug, which is developed by Johnson & Johnson, his scans are looking “very, very good,” he said.
“There are days that you feel strong and there are days that you’re a little weaker, but you just adjust accordingly.”
“Science is catching up to me perfectly with all these drugs that I’m on,” Nitsche said. “Now, we’ll just wait for the next thing to come along, and we’ll jump onto that. But for now, the Rybrevant is working perfectly.”
Nitsche has experienced a few side effects, but said for the most part, the drug he is taking is “very tolerable.” (Dave Nitsche)
Nitsche has experienced a few side effects, primarily skin irritation and fingernail infections, but said for the most part, the drug is “very tolerable.”
Compared to the full-dose chemo and other lung cancer treatments, Farooqui agreed that Rybrevant is “very manageable.”

Other common side effects can include infusion reactions, muscle and joint pain, mouth sores, swelling, fatigue, nausea, bowel changes, vomiting, cough, shortness of breath and low appetite, according to FDA prescribing information.
In rare cases, serious effects can include lung inflammation, blood clots, severe skin reactions and eye problems. Pregnant women should not take the drug due to fetal risks.
Embracing his role as an advocate, Nitsche now speaks openly about his experience and what others should know. (Dave Nitsche)
“If somebody is having too many side effects, or if it is feeling too aggressive, we can do dose reductions,” Farooqui noted. “In my experience, we’ve had patients do really well on it, and we’ve been able to manage their side effects without any major concerns.”

Rybrevant has now been approved to treat certain types of non-small cell lung cancer in the U.S. and Canada, and Nitsche said a few of his friends are also taking the drug.
“Doctors gave me a year to two years – they told me to get my affairs in order. And it’s been seven years now,” he said. “I’ll take it.”
“For almost any type of cancer, a diagnosis is not a death sentence.”
Nitsche is now preparing for a 600-mile biking expedition in June to raise awareness for lung cancer. He credits his endurance training and high fitness level with helping to extend his survival.
“There are days that you feel strong and there are days that you’re a little weaker, but you just adjust accordingly,” he said.

Embracing his role as an advocate, Nitsche now speaks openly about his experience and what others should know.
“If you have lungs, you can get lung cancer – but at this point, for almost any type of cancer, a diagnosis is not a death sentence,” he said. “They’re doing so much research on it, especially with lung cancer… I’ve known people who have lasted 12 to 18 years, so for me, seven years is great. So I’ll just keep going.”

Farooqui echoed the importance of patients “advocating for themselves and getting the most up-to-date therapy there is.”

At 75, Jane Seymour isn’t fighting the years under her belt — she’s leaning into them. The former Bond girl in “Live and Let Die” and star of “Dr. Quinn, Medicine Woman” has a simple outlook on aging: She’s just grateful for the opportunity.
Her perspective shifted radically in her 40s after a near-death experience involving anaphylactic shock, according to an interview the actress did with Women’s Health.
“I remember looking at my body from above and thinking, ‘That’s your vehicle. I am responsible for taking care of this car,’” Seymour recalled.
COMMON EATING HABIT MAY TRIGGER PREMATURE IMMUNE SYSTEM AGING, STUDY FINDS
The actress shared the following four key habits she uses to navigate her 70s with vitality.
1. Embrace a positive attitude

For Seymour, the mental game of aging is just as important as the physical. She said she approaches every day with a sense of optimism, which she describes as “getting up and not giving up.”
In a recent interview with Future of Personal Health, Seymour said that being depressed over lost youth is “redundant.” Instead of mourning the past, she embraces the present.

“You were 20, and you had whatever that experience was,” she said. “Now, maybe you’re 70, and it’s a whole new world.”
2. Know your body
Seymour’s fitness routine is built on consistency rather than intensity, she shared. The actress aims to work out at least three times a week, but refuses to push herself to the point of injury.

“I listen to my body,” she told Women’s Health. “I’m not going to overdo it.”
Seymour’s workouts focus on strengthening her core, arms and legs. While her preference is the reformer (a Pilates machine), she is highly adaptable.

When traveling without workout equipment, Seymour said she performs bodyweight exercises, even doing incline press-ups against a kitchen counter.
“I’m not going to pretend I’m 20 when I’m 70,” she said. “I’m going to be the best I can be at the age I am.”
3. Nourish your body
Rather than fighting the natural signs of a life well-lived, Seymour said she views her appearance as a professional asset.

“I’m not chasing wrinkles,” she added. “My laugh lines and even my frown lines are useful in my work – they’re part of my toolkit.”

This includes a daily regimen of exfoliation and hydration, alongside a diet rich in fruits and vegetables.
“I’m going to be the best I can be at the age I am.”
When her filming schedule makes fresh meals difficult, Seymour supplements with antioxidant blends to ensure there are “no nutritional gaps,” aiming for a holistic balance that allows her to “think sharper and move stronger.”
4. Nourish your mind
Perhaps the most profound tool in Seymour’s toolkit, she said, is her commitment to purpose. Inspired by her mother, a survivor of WWII concentration camps, Seymour believes that longevity is tied to how much one gives back to the world.

“My mother always said there’s someone worse off than you, and you can find purpose by helping others – listening and making them feel heard,” she shared.

This philosophy led Seymour to found the Open Hearts Foundation, a nonprofit that empowers others through grant-making and volunteerism.
“That’s the best way to end the day — knowing it wasn’t wasted.”
