There is also a video clip trending on X in which two of the MrBeast participants spent 163 days in lockdown, lost 160 pounds each, earned $350,000, and surprised their loved ones on their wedding day with their new appearance. This post published by @FearedBuck is no exaggeration; rather, it is an accurate description of an actual challenge which has been posted recently.
MrBeast released the full video, “Lose 150 Lbs Together, Win $250,000,” on October 17, 2026. Engaged couple Sara and Tre (also referred to as Sarah and Trey in some coverage) moved into a custom gym compound built for the challenge. A red boundary line surrounded the property. Crossing it early meant the challenge was over and the money was gone. They stayed inside for the full 163 days.
The two participants began with a weight of 345 pounds and 249 pounds respectively. They received professional assistance from iFIT trainers, John Peel and Bree Cox as well as regular testing by Function Health who found out pre-diabetic biomarkers at the start. The progress has been measured regularly: 43 pounds lost in 30 days, 76 pounds in 60 days, 107 pounds in 90 days and 144 pounds in 150 days. Finally, on the 163rd day, the total of 160 pounds lost was reached.
The main prize was $250,000. Side challenges deadlifting a cash-loaded bar, a helicopter cargo-net climb for a Hawaii honeymoon, truck pulls, and solo final tests added another $100,000. MrBeast deposited $175,000 into each of their Step accounts for a $350,000 total. Vehicles and a full wedding production were part of the package too.
It was all about the proposal. Both families had not been able to see their children in weeks. It was the first time that either family had seen Sara and Tre since they started their mission. They both got married on the set after the final weighing. All the hard work and training paid off.
They were both living in a compound during the filming where they trained and had to follow a strict set of guidelines. They weren’t exactly being held against their will as there were trainers, doctors, and producers. But living in the compound with the red line and having to stay for 163 days sounds about right.
The core claim holds up. Sara and Tre did spend 163 days under isolation rules, lost a combined 160 pounds, earned $350,000 in total prize money, and revealed their transformations at their wedding. The only minor clarification is that the $350,000 combined the $250,000 base prize with side-challenge earnings rather than arriving as one lump sum. Everything else checks out against the primary source.
