One in every eight people globally qualifies as obese, according to a new study published in The Lancet on Feb. 29.
As of 2022, more than one billion people — 43% of adults — were living with obesity across the world, according to researchers from the NCD Risk Factor Collaboration, a global network of health scientists.
The number of obese adults has more than doubled since 1990.
Among children between ages five and 19, the obesity rate has quadrupled, according to a press release from the World Health Organization (WHO).

The researchers analyzed data from 3,663 population-based studies with 222 million participants, using different body mass index (BMI) measurements for adults, children and teens.
The data was collected between 1990 and 2022 across 200 countries and territories, according to the findings in The Lancet.

Out of the 200 countries, the U.S. ranked 36th for obesity.
“This new study highlights the importance of preventing and managing obesity from early life to adulthood, through diet, physical activity and adequate care, as needed,” said Dr. Tedros Adhanom Ghebreyesus, director-general of WHO, in the release.

“Getting back on track to meet the global targets for curbing obesity will take the work of governments and communities, supported by evidence-based policies from WHO and national public health agencies,” he went on.
“Importantly, it requires the cooperation of the private sector, which must be accountable for the health impacts of their products.”

Dr. Marc Siegel, clinical professor of medicine at NYU Langone Medical Center and a Fox News medical contributor, said the world is in “big trouble” in terms of undernutrition and obesity.
“In terms of undernutrition, it is a public health challenge in many places, including Asia and Africa, though overall rates have dropped,” Siegel, who was not involved in study, told Fox News Digital.
“We have far too much processed food with chemicals that produce weight gain.”
“By comparison, obesity is exploding,” he added.
A primary cause of obesity is poor diet, including too many carbohydrates and fats and too few proteins and vegetables, according to the doctor.
“In poor areas, this may be cost-related in part,” he said.
What can be done?
In cases where it’s not an economic issue, Siegel suggested countering obesity by increasing the intake of vegetables, fiber and fish and decreasing the consumption of alcohol, bread, pasta, rice and desserts.

“We have far too much processed food with chemicals that produce weight gain,” said Siegel. “We should fight back by trying to use natural foods (farm to table) as much as possible.”
He also emphasized the importance of eating smaller portions, increasing water intake and exercising regularly to help reduce hunger and cravings.

“We also have effective weight loss drugs — semaglutide (Ozempic and Wegovy) and tirzepatide (Mounjaro and Zepbound) — but they should be reserved for those who are truly obese and have failed lifestyle modifications above,” Siegel said.

“Diabetics must be first in line for these drugs as production shortages are overcome, followed by those most in need, but they can certainly make a difference in terms of improving insulin function, improving efficiency of glucose metabolism and decreasing hunger.”
Obesity is a primary driver of the leading causes of death, including diabetes, heart disease, stroke and some types of cancer, according to the Centers for Disease Control and Prevention (CDC).

Hiker's death in Utah spotlights need for safety protocols on the trail
![Hiker's death in Utah spotlights need for safety protocols on the trail Hiker's death in Utah spotlights need for safety protocols on the trail](https://static.foxnews.com/foxnews.com/content/uploads/2024/07/female-hiker.jpg)
A female hiker died on Sunday on a trail near near Quail Creek State Park in southern Utah, according to local reports.
The woman, 56, who was not identified in the report, had sent out a distress call regarding lack of water and high temperatures, but by the time police arrived, she was unresponsive and pronounced dead at the scene.
The local temperature was 106 degrees Fahrenheit when the woman’s death was reported.

This recent hiking death and others, many of them heat-related, have spotlighted the need for safety protocols.
While experts agree that hiking is considered a good form of exercise, they stress the importance of being prepared before heading out on the trail, especially during the hot summer months.
Outdoor enthusiasts shared tips to help prevent trail hazards amid a flurry of recent hiking-related deaths this summer. (iStock)
Outdoor enthusiasts shared the following important tips to help prevent hiking hazards.
1. Study the hiking area before your trip
Before heading out on a hike, familiarize yourself with maps, landmarks and any restricted areas or required permits, say trail experts.
“Research the terrain, trail difficulty, weather conditions and local wildlife,” Joey Coe, a trip leader for Backroads, a California-based travel touring company, told Fox News Digital.

Coe also suggested saving a photo of the trail map on your phone to reference while hiking.
Although cell phones and mapping apps can be helpful, it is important to have a backup paper map in the event of a lost signal, according to Guy deBrun, a lecturer at the Hart School of Hospitality, Sport & Recreation Management at James Madison University in Virginia.
WHAT IS A DERECHO? HERE’S A METEOROLOGICAL EXPLANATION AND OTHER INTERESTING FACTS
“Knowledge of how to use a paper map is imperative,” deBrun, who is also an instructor in wilderness first aid, told Fox News Digital in an email.
Hikers should also know the difficulty level of the planned route, according to the American Hiking Society, a nonprofit based in Silver Springs, Maryland.

Pack lightweight, high-energy foods such as nuts, dried fruit, energy bars and sandwiches, and avoid bringing perishable items unless you have proper storage, experts said regarding outdoor hikes. (iStock)
“It’s also helpful to identify possible emergency exit points,” Maggie Peikon, manager of communications with the American Hiking Society, told Fox News Digital via email.
Online forums and trail reviews can also provide valuable information about the terrain, she added.
2. Set a ‘time plan’ for your hike
Whether you are setting off alone or with a group, let someone know your expected time frame for arriving at predetermined spots along the trail, experts recommend.
“Knowledge of how to use a paper map is imperative.”
One approach is to create a “time control plan,” which considers linear distance and elevation.
A general rule of thumb is to travel two miles per hour, adding one mile for every 1,000 feet of elevation gain.
“Most novices fail to plan for elevation gain,” deBrun told Fox News Digital.
TIKTOK TRENDING QUESTION ABOUT ‘BEING STUCK IN A FOREST’ WITH ‘A MAN OR A BEAR’ YIELDS STRATEGIC TIPS
“One thousand feet of elevation gain adds one mile to your total mileage. So, if you are hiking five miles and gaining 2,000 feet, you [should] consider it seven miles. Divide by two miles an hour to estimate your time.”
It is also important to project the amount of daylight you will have during your excursion to avoid returning in the dark if you don’t have the necessary gear to hike at night.
3. Know your limits
It’s best to start small and build, starting with short, easy, well-marked trails that match your fitness level, experts agreed.
“Take breaks as needed, and don’t push too hard,” said Coe.
Peikon added, “If you’re feeling too tired, or realize you’re not going to make it to your destination within the time frame you prepared for, turn around and err on the side of caution.”

Before heading out on a hike, trail experts recommend familiarizing yourself with maps, landmarks, and any restricted areas or required permits. (iStock)
It’s also important to stay on the trail, she said.
“Avoid taking shortcuts. Getting off the trail for any reason can easily result in becoming directionally disoriented and getting lost.”
4. Maintain a safe distance when hiking
Aim to keep a distance of at least a few feet between hikers to avoid accidents and allow space for wildlife, experts advised.
For people hiking in a group, it’s best to avoid taking up the whole trail width, according to the American Hiking Society.
WEAR SUNSCREEN THE RIGHT WAY THIS SUMMER BY UNDERSTANDING SPF AND THE PROPER APPLICATION PROCESS
Hikers going downhill should yield to those going uphill.
Also, be wary of potential poisonous vegetation in that region so you can keep a safe distance and avoid accidental contact, experts cautioned.
5. Prepare for weather conditions
Hikers should consider local weather patterns when deciding what to wear on a hike, experts told Fox News Digital.
“In many mountainous areas, lightning storms regularly occur in the afternoon,” deBrun said. “Hikers should take this into account.”
Coe recommended dressing in layers to help adjust to changing temperatures.
“Moisture-wicking, quick-drying materials are best,” he said.

In areas where bears are prevalent, experts suggest packing bear spray to use in the event of an unexpected encounter. (iStock)
Bring a hat, sunglasses, sunscreen and rain gear, experts advised.
For family hiking trips, it’s important to be aware of children’s body temperature. “If you are carrying a child, he or she may be cold while you are burning up,” Peikon said.

“Conversely, you may feel chilled while your child is warm from running around and playing.”
If multiple children are on the hike, dress them in bright, visible clothing so you can more easily spot them, Peikon said.
6. Wear comfortable, supportive footwear
Multiple hiking trip leaders suggested wearing sturdy, well-fitted hiking boots with good ankle support.
“Break them in before your trip to avoid blisters,” Coe cautioned.

Running shoes or trail runners can be appropriate, deBrun said, but hiking boots may be more appropriate in wet or rocky terrain.
7. Bring along essential equipment
Pack a compass or GPS, whistle, flashlight, a basic first aid kit and trekking poles (if needed), said experts.
Teach children to blow the whistle several times in the event they wander away from the group, they also advised.

“Be aware of your group’s medical needs and any potential allergies,” Coe said.
Hikers might also want to consider taking a wilderness first aid course, he added.
In areas where bears are prevalent, experts suggest packing bear spray to use in the event of an unexpected encounter.
It’s also a good idea to check with local animal experts about how to navigate an encounter with wildlife.
8. Stay fueled and hydrated
Pack lightweight, high-energy foods such as nuts, dried fruit, energy bars and sandwiches, and avoid bringing perishable items unless you have proper storage, experts said.

Aim to keep a distance of at least a few feet between hikers to avoid accidents and allow space for wildlife, experts advised. (iStock)
It is also important to leave no trace of food behind.
“Carry out all trash and leftover food to avoid attracting wildlife and to prevent littering,” Coe advised.

Packing enough water is essential.
“Bring at least half a liter of water for every hour you plan to be hiking,” Peikon said — even more when hiking in the heat.

Selfies can distract hikers from their surroundings, which can increase the risk of falls or cause them to miss a hazard, according to hiking experts. (iStock)
Very few water sources are safe to drink without purification, deBrun cautioned.
“Research water sources and bring a water purification system for longer hikes,” he said.
9. Use caution with cellphones and selfies
Selfies can distract hikers from their surroundings, which can increase the risk of falls or cause them to miss a hazard, according to hiking experts.
“It is always tragic to hear of fatalities due to selfies, which does happen every year in U.S. national parks,” Coe told Fox News Digital.

Experts laud injection that reportedly offers 100% protection against HIV/AIDS
![Experts laud injection that reportedly offers 100% protection against HIV/AIDS Experts laud injection that reportedly offers 100% protection against HIV/AIDS](https://static.foxnews.com/foxnews.com/content/uploads/2024/07/HIV.png)
- Twice-yearly shots used to treat AIDS were 100% effective in preventing new infections in women, according to a new study.
- There were no infections among the young women and girls who received the shots in a study of about 5,000 participants in South Africa and Uganda.
- The shots, made by U.S. drugmaker Gilead and sold as Sunlenca, are currently approved as a treatment for HIV in several regions.
Twice-yearly shots used to treat AIDS were 100% effective in preventing new infections in women, according to study results published Wednesday.
There were no infections in the young women and girls that got the shots in a study of about 5,000 in South Africa and Uganda, researchers reported. In a group given daily prevention pills, roughly 2% ended up catching HIV from infected sex partners.
“To see this level of protection is stunning,” said Salim Abdool Karim of the injections. He is director of an AIDS research center in Durban, South Africa, who was not part of the research.
PIONEER OF AMERICA’S GLOBAL HIV/AIDS PROGRAM RECALLS HOPE AFTER YEARS OF DESPAIR
The shots made by U.S. drugmaker Gilead and sold as Sunlenca are approved in the U.S., Canada, Europe and elsewhere, but only as a treatment for HIV. The company said it is waiting for results of testing in men before seeking permission to use it to protect against infection.

The results in women were published Wednesday in the New England Journal of Medicine and discussed at an AIDS conference in Munich. Gilead paid for the study and some of the researchers are company employees. Because of the surprisingly encouraging results, the study was stopped early and all participants were offered the shots, also known as lenacapavir.
While there are other ways to prevent HIV infection, like condoms or daily pills, consistent use has been a problem in Africa. In the new study, only about 30% of participants given Gilead’s Truvada or Descovy prevention pills actually took them — and that figure dropped over time.
The prospect of a twice-a-year shot is “quite revolutionary news” for our patients, said Thandeka Nkosi, who helped run the Gilead research at the Desmond Tutu Health Foundation in Masiphumelele, South Africa. “It gives participants a choice and it just eliminates the whole stigma around taking pills” to prevent HIV.
HIV/AIDS CAN BE ELIMINATED BY 2030 IF COUNTRIES TAKE THE CORRECT STEPS, ACCORDING TO UN
Experts working to stop the spread of AIDS are excited about the Sunlenca shots but are concerned Gilead hasn’t yet agreed on an affordable price for those who need them the most. The company said it would pursue a “voluntary licensing program,” suggesting that only a select number of generic producers would be allowed to make them.
“Gilead has a tool that could change the trajectory of the HIV epidemic,” said Winnie Byanyima, executive director of the Geneva-based U.N. AIDS agency.

She said her organization urged Gilead to share Sunlenca’s patent with a U.N.-backed program that negotiates broad contracts allowing generic drugmakers to make cheap versions of drugs for poorer countries worldwide. As an HIV treatment, the drug costs more than $40,000 a year in the U.S., although what individuals pay varies.
Dr. Helen Bygrave of Doctors Without Borders said in a statement that the injections could “reverse the epidemic if it is made available in the countries with the highest rate of new infections.” She urged Gilead to publish a price for Sunlenca that would be affordable for all countries.
In a statement last month, Gilead said it was too early to say how much Sunlenca would cost for prevention in poorer countries. Dr. Jared Baeten, Gilead’s senior vice president of clinical development, said the company was already talking to generics manufacturers and understood how “deeply important it is that we move at speed.”
Another HIV prevention shot, Apretude, which is given every two months, is approved in some countries, including in Africa. It sells for about $180 per patient per year, which is still too pricey for most developing countries.

Byanyima said the people who need long-lasting protection the most include women and girls who are victims of domestic violence and gay men in countries where same-sex relationships are criminalized. According to UNAIDS, 46% of new HIV infections globally in 2022 were in women and girls, who were three times more likely to get HIV than males in Africa.
Byanyima compared the news about Sunlenca to the discovery decades ago of AIDS drugs that could turn HIV infection from a death sentence into a chronic illness. Back then, South African President Nelson Mandela suspended patents to allow wider access to the drugs; the price later dropped from about $10,000 per patient per year to about $50.
Olwethu Kemele, a health worker at the Desmond Tutu Health Foundation, predicted the shots could boost the number of people coming in for HIV prevention and slow the virus’ spread. She said young women often hide the pills to avoid questions from boyfriends and family members. “It makes it hard for the girls to continue,” she said.
In a report on the state of the global epidemic released this week, UNAIDS said that fewer people were infected with HIV in 2023 than at any point since the late 1980s. Globally, HIV infects about 1.3 million people every year and kills more than 600,000, mainly in Africa. While significant progress has been made in Africa, HIV infections are rising in Eastern Europe, Latin America and the Middle East.
In other research presented at the AIDS conference, Andrew Hill of the University of Liverpool and colleagues estimated that once production of Sunlenca is expanded to treat 10 million people, the price should fall to about $40 per treatment. He said it was critical that health authorities get access to Sunlenca as soon as possible.
“This is about as close as you can get to an HIV vaccine,” he said.
