Swedish Man’s 4-Week Chinese Fat Camp Transformation

Last updated: October 6, 2026

A Swedish traveller has gone viral after documenting the physical overhaul he credits to a four-week fitness program in southern China. According to boredpanda.com, André Helgesen, a former system technician who quit his job to backpack across Asia, joined a Shenzhen-based "fat camp" and walked out noticeably leaner, on top of weight he had already shed on his own.

His before-and-after mirror selfies, posted to TikTok under the handle @imhelgis, show a body that has changed dramatically in a matter of months, and the story behind those images is stranger and more disciplined than a typical gym transformation.

At a glance

• Helgesen is Swedish and had already dropped about 7.8 stone (roughly 49 kg) before arriving at camp, going from over 21 stone (133 kg) to around 13 stone (82 kg).
• The program is run by a company called Jianfeidaren in Shenzhen, China, and runs for four weeks.
• It pairs three daily workouts with structured meals, medical checkups, and mental health support.
• Participants eat about 1,300 calories a day, creating roughly a 1,000-calorie daily deficit, and fast from around 5:00 pm until 8:00 am the next morning.
• After 28 days at camp, Helgesen lost another half a stone (about 3.2 kg), bringing his total weight loss to more than 8 stone (over 50 kg).

How he got there

Helgesen said he had carried body insecurity with him for years, and that the camp was the kickoff for a longer Asia trip rather than a quick fix. He found Jianfeidaren, a well-known four-week fitness program in Shenzhen, while scrolling Reddit for "fat camp" options. He picked it because it bundled exercise, food, checkups, and mental health support under one roof, and then flew to China to start.

He filmed the whole thing. Daily routines at the camp start at 7:30 am and end at 9:30 pm, with badminton classes, group training, and a buffet that even includes pasta. The non-negotiable part, in his telling, was the fasting window. Dinner lands at 5:00 pm, and the next bite is breakfast at 8:00 am, a 15-hour gap that he openly admits he sometimes broke with a sneaky apple.

What changed at the camp

The most counter-intuitive detail from Helgesen's write-up is that nobody was policing his food. Staff laid out the schedule and the meals, but if he wanted to cheat, he could have. The point of the program, as he described it, was to recreate real-life temptation and force each participant to manage it themselves. Personal trainers joined the three daily workouts rather than barking orders from the sideline, and the trainers stayed friendly even with a non-Mandarin speaker in the group.

The fitness side is half the story. The other half is the calorie math. At roughly 1,300 calories per day against his baseline needs, the program built a 1,000-calorie deficit into every 24 hours, which is the kind of arithmetic that explains the half-stone drop in four weeks on top of his earlier loss. Researchers have noted in published studies that combining diet and exercise tends to outperform either one alone, and that even short structured programs can move the needle on body composition, blood markers, and mood. The 28-day result was modest on paper but a morale bomb for him, and the shirtless mirror selfies were the receipt.

Our analysis

The appeal of this story is less "extreme weight loss" and more "structured environment with built-in temptation tests." Most viral fitness tales hinge on either a magic supplement or a punishing drill sergeant. This one sells a different pitch: no one is coming to save you, so stop waiting. For casual readers who scroll past gym content all day, that's a sharper hook than another smoothie recipe.

Who it actually speaks to: people who know they should change a habit but keep negotiating with themselves. The camp is essentially a four-week sabbatical from your kitchen, your phone, and your excuses. Who it doesn't help: anyone who can't take a month off, can't travel, or has a medical condition that makes 1,000-calorie deficits unsafe. A 1,300-calorie-a-day plan is a serious restriction and should not be copy-pasted into a normal life without medical input.

The honest trade-off is psychological. Helgesen talks about losing more than weight. He talks about shedding the identity of "the big person." That's a real win, but it's also the part of the story that does not survive contact with a normal routine. Once the schedule, the trainers, and the buffet disappear, the same person is standing in their own kitchen at 10 pm. The camp didn't break his habits so much as prove he could run someone else's program. The hard part comes after the flight home.

What it means for you

Say you are a regular reader who has been "thinking about" signing up for a fitness retreat for two years. The useful question this story raises is not whether you can survive a Chinese boot camp. It is what stripped-down version of that structure you can copy. Helgesen's three pillars are boring on purpose: a fixed wake-up time, meals someone else decided, and a hard cut-off in the evening. None of that requires a plane ticket. A month of pre-planned dinners, a daily 7:30 am alarm, and a kitchen that closes at 5:00 pm would replay most of the same effect at home, with far less drama and a much smaller bill.

It also helps to be honest about what a "fat camp" is and is not. It is a temporary, supervised, high-control environment. It is not a lifestyle, and the after-photos are not the product. The product is the proof-of-concept that you can run a strict routine for 28 days without falling apart. The half-stone lost at camp is a nice number. The real number is the 8-stone total, and that only happened because he kept going when the structure was gone.

What to watch next

Watch whether Helgesen keeps the weight off once the camp glow fades, because that is the part of every transformation story that actually decides whether the photos mean anything. Watch how Jianfeidaren and similar programs handle the post-camp period, since retention is the industry's weak spot. And watch for more Western influencers booking these trips, because a Reddit-friendly "fat camp" abroad is exactly the kind of content that travels.

Key takeaways

• The camp itself produced a modest 3.2 kg loss in 28 days; the dramatic 50 kg total came from Helgesen's own longer effort.
• The program's real hook is psychological: structured temptation testing instead of a strict overseer.
• A 1,000-calorie deficit is aggressive and should not be self-prescribed without medical guidance.
