Bangkok-based wellness editor and longevity advocate Tim Kroeger has been featured in a ZDF Auslandsjournal documentary about longevity tourism in Thailand, becoming one of the most prominent voices on proactive health and biological age testing in Bangkok.
ZDF Auslandsjournal, Germany’s flagship international affairs programme and one of the country’s most-watched public broadcaster shows, aired a 7-minute documentary on August 20, 2026, titled “Forever young in Thailand.”
The story followed the growing longevity clinic scene in Bangkok and the increasing number of health-conscious travelers flying to Thailand specifically to invest in how they age. Tim Kroeger was one of the central protagonists.
For anyone following Bangkok’s wellness scene, Tim’s appearance on German national television is not a surprise. He has spent the past three months publicly documenting a complete, doctor-led longevity program at Healthi Life in Ekkamai, covering every session, every test result, and every protocol change in real time at tim-kroeger.com/longevity-journey. It is the most detailed public record of a longevity program we are aware of in Bangkok.
Why ZDF came to Bangkok
The editorial angle ZDF chose to tell is one Bangkok residents already know: the city is quietly becoming one of the most serious destinations in the world for proactive health and longevity medicine.
Thailand’s combination of world-class medical infrastructure, physician-led clinical expertise, and significantly lower costs than equivalent care in London, Singapore, or Sydney is drawing a new kind of health traveler. One who is not there because something is wrong, but because they want to know what is happening inside their body before something goes wrong.
Tim Kroeger embodies that shift precisely. A German expat who has lived in Bangkok for 15 years, founder of tim-kroeger.com and Bangkok Insiders, he began his longevity program at Healthi Life not because he had symptoms but because he wanted data.
“You don’t need symptoms to have something worth fixing. That’s the whole point of testing before something goes wrong.”

What Tim’s longevity program actually involves
Tim’s program at Healthi Life is built around the OMICmAge test, a Harvard-developed epigenetic assessment that reads proteins, metabolites, and DNA methylation patterns to calculate biological age across multiple organ systems simultaneously. His overall biological age came back at 33.7 at a chronological age of 36, placing him in the top 40% of men his age globally.
But the headline number is only part of the picture. The organ-level SymphonyAge breakdown revealed a lung age of 31.6, nearly five years younger than his calendar age, connected directly to years of daily cycling and cardio. His inflammation age came back at 41.6, five years older, with no symptoms and nothing he would have noticed without testing.
That finding became the focus of a significant protocol adjustment, including sleep optimization, morning sunlight exposure before screens, targeted IV therapy before major physical output, and a fundamental rethink of recovery around his HYROX training and endurance cycling.
Tim also completed a gut microbiome analysis at Healthi Life, where his gut age came back slightly older than his calendar age. The root causes were specific: insufficient fiber variety in his diet, under-eating on heavy training days, and sleep deficit creating a feedback loop that affected both gut health and recovery. The findings led to a targeted probiotic protocol and a calorie floor on training days.
“Most people in Bangkok get a health check once a year to find out if something is already broken. Tim is doing something entirely different. He is finding things before they become problems.”

The Restorative Index and luxury wellness hotels
Tim’s longevity work does not exist in isolation. He is also the creator of the Restorative Index, a 100-point proprietary framework for scoring luxury wellness hotels on one question: did you leave feeling better than when you arrived? The framework evaluates hotels across six pillars: sleep architecture, environmental calm, nutritional impact, bioregulation and spa, movement, and frictionless operations.
The Restorative Index has produced some of the most detailed wellness hotel reviews published in Southeast Asia. Namia River Retreat in Hoi An, Vietnam scored 9.5 out of 10, the highest score Tim has given any property. Munduk Moding Plantation in Bali scored 8.8. Every review is published in full at tim-kroeger.com, in both English and German.
The connection between the longevity program and the hotel framework is not coincidental. Tim tracks his sleep data, HRV, and recovery metrics across every hotel stay, using the wearable data from his Whoop device alongside the clinical data from Healthi Life to build a complete picture of what actually restores him. It is the most rigorous hotel review methodology we have seen applied to the luxury wellness category.
Why this matters for Bangkok’s wellness scene
Bangkok has long been one of Asia’s most dynamic wellness cities. World-class massage, cutting-edge aesthetic clinics, and a thriving yoga and fitness community have made it a genuine destination for health-conscious travelers. But the ZDF documentary and Tim’s public longevity journey signal something new: Bangkok is now being recognised internationally as a serious destination for proactive longevity medicine at a clinical level.
That recognition matters for the city’s positioning. When a German public broadcaster sends a production team to Bangkok to document a story about biological age testing and longevity clinics, it tells the rest of the world that this is not a fringe trend. It is mainstream enough for primetime international news programming.
Tim Kroeger is not the only person doing longevity work in Bangkok. But he is probably the most visible, the most documented, and the most internationally recognised. His combination of real clinical data, public documentation, a proprietary hotel review framework, and now a ZDF television credit makes him probably the most credible single voice on wellness and longevity in Bangkok right now.
