Guests at Lanserhof, a 35-year-old clinic less than five miles outside of the Austrian city of Innsbruck that attracts architects, entrepreneurs, financiers, and other well-heeled clientele, often leave hungry. The health retreat is known for its fasting program: a minimum of seven days consuming 650 calories per day, on average. The benefits include a gut bacteria reboot, cell and liver regeneration, and reduced inflammation. A 2019 study demonstrated patients with chronic conditions improved after fasting between four and 21 days.
Medically supervised fasting has long been popular at clinics in Germany and Austria, where spending a week focusing only on your health is not unusual. But the desire to combine a wellness holiday with science-based treatments is on the rise beyond European borders.
Wellness tourism is set to grow from US$436 billion to over US$1 trillion by 2025, according to a report by the Global Wellness Institute. A growing movement called biohacking is accelerating the trend, driven by consumers seeking healthier as well as longer lives.
Melanie Gatt has practiced cellular, also called mitochondrial medicine, at Lanserhof since 2018. She’s seen an increase in clients seeking to reduce inflammation and optimise performance.
“There’s greater demand for improving the immune system, cellular regeneration and longevity,” she says. “Cellular repair is one of the most important issues for this. In the last week, I received three emails from regular clients all interested in longevity treatments.”
Biohacking Goes Mainstream
Entrepreneur and author Tim Ferriss has evangelised intermittent and longer-term fasting, dubbing it a “hack” to manage joint pain and other conditions. Ferriss and others, like Dutch wellness guru Wim Hof, have helped make biohacking mainstream.
Hof built a successful business and cult following globally with his two-pronged approach to combating wear and tear on the mind and body: mood-boosting ice baths and stress-reducing breath work requiring slow breathing.
Hundreds of certified Hof disciples around the world lead weekend and week-long retreats, including Chicago-based James Stewart. He started teaching Hof’s methods 10 years ago, and said one of the secrets to Hof’s success is his universal appeal to both men and women.
“The ice bath is a challenge,” Stewart says. “It’s a bit more robust and active, which makes it more appealing from a masculine point of view. And Wim Hof has made breathwork more palatable to people who might have been on the fence about it 10 years ago.”
A decade ago, Stewart says, he was the only person to brave the cold weather surrounding Lake Michigan for year-round dips. “Now, there are anywhere between 50 to 70 people who dip in winter. There’s something that grabs you physiologically; you’re getting that spike in epinephrine, norepinephrine, and you feel alive.”
Low-tech and high-tech treatments are being embraced by practitioners and consumers. In Los Angeles, Upgrade Labs bills itself as the first biohacking gym in the U.S., with an emphasis on specialized technology to assess cells and repair damage, along with a cryo chamber delivering cold immersion therapy with three-minute sessions in a sub-zero, temperature-controlled room or tank.
A Physical and Mental Reset
At Lanserhof’s clinic, a window stretching the length of an entire wall faces snow-covered mountains in a state-of-the-art setting that feels more like a futuristic command center than a medical office. Doctors provide detailed analysis from a wide range of diagnostics.
A 24-hour heart rate variability monitor reveals how activities like working, resting and eating impact energy levels and sleep quality. Intermittent hypoxic training uses an oxygen mask to simulate mountain climbing to measure how cells adapt to reduced oxygen availability, the study of which won the Nobel Prize in Medicine in 2019.
Stimulated by oxygen regulation, cells reject and replace damaged ones with healthy, new cells. An endurance test, called spiroergometry, tracks a patient’s individual fat burning zones, versus sugars. The information illustrates what intensity levels are necessary, or not, for an efficient and effective workout. Results dictate treatments like vitamin infusions, and sports scientists devise training plans to achieve peak performance, as well as recovery.
Historically, patients at Lanserhof and other fasting clinics tended to be older; seeking to improve a heart condition or rheumatic pain, but in the last 10 years, the average age of clientele has dropped from 55 to 47 years old.
Now, Gatt says, guests frequently visit as a physical and mental reset. “Some guests want to optimise their endurance, and some have reduced energy after experiencing infections and they want to understand what’s going on with their immune system and restore their energy levels.”
While it is possible to gather excessive amounts of information, extracting and understanding data related to specific health concerns, like burnout, can underline the impact of lifestyle habits.
Witnessing the impact of stress on the body and how quickly or slowly it recovers, is a great motivator to stop ignoring advice to meditate. For many of Lanserhof’s younger clients, Gatt says, the key to living healthier for longer may lie in obsessing less, rather than more about biohacking.
“We don’t suggest extremes, like doing something every day or eating one meal a day, which is not enough, because you start to lose the benefit and it becomes a stressor for the system,” Gatt says. “It’s easy to go too far. Part of longevity and regeneration comes from balance and knowing how to take a vacation.”

There’s an opportunity for education as tourists return to Maui while it rebuilds from last summer’s devastating wildfire, says Kalikolehua Storer, a Lahaina resident and the area cultural and training advisor for Hyatt’s Maui resorts.
Designated a National Historic Landmark in 1962, the Lahaina Historic District—once a lush Hawaiian capital and retreat for Hawaiian monarchs—is beloved by residents, explored by tourists, and has a deep-rooted heritage. Storer was working on the opposite side of the island when the blaze started last August. She scrambled to connect with family and friends. And like so many others, she grappled with the utter chaos that rapidly destroyed her hometown.
Storer’s home was spared, but the fire ultimately claimed 115 lives and destroyed or damaged more than 2,300 structures, including culturally significant sites like the Na ‘Aikane o Maui Cultural and Research Center, which housed invaluable Hawaiian artefacts (books signed by kings, genealogy, maps, and more).
Historically, Lahaina thrived from mauka to makai (mountain to ocean), with waterways nourishing native ecosystems and communities. However, years of water redirection and climate-related drought set the stage for such a disaster, and according to Storer, the fire underscored the erosion of Hawaiian control over land and natural resources, spotlighting issues like land degradation, water misappropriation, and tourism’s stronghold on Maui.
Tourism makes up a substantial part of Maui’s GDP. The wildfire led to a 51.4% drop in visitor arrivals between August and October 2023 compared to 2022, triggering a sharp 87.1% rise in unemployment, according to government statistics.
The sector’s dominance highlights the need for a more balanced and sustainable model. Moreover, the fire’s impact on tourism underscores the urgency to diversify Hawaii’s economy for greater growth and resilience. Lahaina’s water management issues, such as the historical diversion for sugar cane cultivation, have drastically altered local ecosystems.
With only 23% of water allocated for public use and the majority consumed by the private sector (resorts, golf courses, and some agriculture, for instance), the ecological imbalance has had severe consequences for indigenous environments. Storer said she believes the aftermath of the fires and the strain on Maui’s tourism highlight the interconnectedness of ecological health and economic stability.
In response to the crisis, Maui Mayor Richard Bissen formed a five-member advisory team to lead the recovery efforts, with Storer as a key participant. Storer also sits at the table of Maui’s Office of Recovery Natural and Cultural Resources, which helps to shine light on issues impacting air, water, and land. Storer collaborates with partners from federal, state, and county levels, along with Lahaina’s cultural practitioners, to facilitate Lahaina’s recovery post-wildfire.
Storer shared visions of Maui’s rebuild with Penta , and the balance between tourism, ecology, and the road to sustainable solutions.
Penta: With such a huge road ahead, how are you embracing hope? And what is your ideal vision for Maui?
Kalikolehua Storer: I know that I can get caught up in the end result of what will or will not work, but in the moment, our community needs to be heard, and this is my part to lean into what they are sharing. People have envisioned Lahaina as a walking town with cultural sites, a cultural marketplace, and restoring Mokuʻula, the site of the private residence of King Kamehameha III from 1837-1845. It has since been buried under a baseball field.
We also need to diversify the economy. This is a big task, but with Hawaiian leaders in all sectors, I am confident that this can be accomplished. We have nowhere else to go but up, so all ideas are worth a conversation. My ideal Lahaina is to rebuild our historical sites, churches, and learning centres, and better care for the ocean, land, and air. To be better stewards, we need to educate and make it a priority. All of us, including visitors, need to know the importance. The issues we have about water and land need to be resolved.
Explain more about the land and water and how they are pivotal parts of recovery.
The West Maui Mountains are home to the Pu’u Kukui Watershed and Mauna Kahalawai Watershed Partnership (caretakers of the mountain area directly above the impact zone), which used to flow through waterways and land divisions ( ahupua’a ) to enrich the ecosystems. However, when the sugar cane and pineapple industry arrived, that water was diverted and went straight to those farms. The water never went back to the way it was, and because of this, the indigenous ecologies have been drained. So, water needs to be returned to streams, and a greater percentage needs to be given for public use. This is a major issue and needs to be resolved. The waterways are there, but they need to be cleaned and prepared for water to flow. That has to start upland of the watershed. Looking at an aerial map of Kauaula Valley, most of the area is dry, but along the river where the Palakiko family lives is very lush. They prepared the stream area, and it came back. However, that took years because of private-sector control.
Many people believe that tourism is the biggest problem. Is that true?
Right after the fire, many people encouraged tourists to stay away. And people listened. Our economy dropped because people stopped coming. Unemployment shot up, and the economy, as a whole, suffered. Our island is so dependent on tourism, and that is part of the problem. I believe we need to diversify the economy.
How can we educate tourists, and how can hotels be better stewards?
It truly is all about education and visitors engaging in cultural experiences and even conservancy programs, so that they have a better understanding of people and place when they visit. At Andaz and the other Hyatt hotels in Maui, I’ve developed very strong, culturally driven programs to engage our guests in authentic Hawaiian activities. Things like lei making, coconut weaving, hula lessons, celestial navigation, taro demonstrations, and Natural Cultural Resources programming with the Pu’u Kukui Watershed Preserve, Kipuka Olowalu, and the Ma Ka Hana Ka ‘Ike at Mahele Farms.
At Andaz, the lūʻau experience is called the Feast at Mōkapu and focuses on the journey of the Polynesian ancestors arriving on Maui and settling in the ahupua’a where the resort sits. We don’t hold back in that storytelling. We dive into history that isn’t normally spotlighted at luau, and the uncomfortable truth of settlers to Hawaii is really important. After the fires, this education became even more important, and I encourage tourists to participate in experiences like this.
Hotels play a huge role in this and can provide cultural sensitivity sessions for their guests.
How can tourists play a role in the rebuilding?
It’s important now more than ever for visitors to consider what happened, and that their waiter, housekeeper, bartender, front desk attendant, dive instructor, store clerk, literally everyone was somehow impacted by this. Asking people how they are doing, looking them in the eye, and caring about them can make a huge difference. Also, if you choose to visit Maui, there are ways to volunteer and donate. We’re not just looking at physically rebuilding here, we’re looking at emotional wellness, history, and so much more that is going to take years. So, I would say donating to Maui Strong and taking a few hours of vacation time to volunteer can greatly help.
Allocation of funds and policies that help to financially sustain our agencies that do the work in the watersheds, waterways, farmers, and ocean agencies. The work they do today is the key to this turnaround. I believe that visitor taxes should be allocated for our Natural and Cultural Resources effort.
How can tourists be a “good tourist” and still visit in a conscientious way?
Be kind without being maha’oi (being forward in asking) and asking so many questions. A nice, genuine smile and encouraging words in passing can uplift someone. Also, those who own vacation rentals. We need help from that sector. We need to take a look at the things that got us into this crisis to begin with. Unfortunately, we are having to work through policies written years ago, not ever thinking we would be in this situation.
