DietBet review: your pot, minus a cut they don’t publish
The money in a DietBet pot is the players’ own money. The rules say winners split it after “DietBet’s cut” and never say how big that cut is.
How a game works
You join a game, put money in, and weigh in at both ends with photos. Everyone’s money goes into one pot and the winners split it. A Kickstarter asks for 4% of your starting weight in 28 days. A Transformer asks for 10% over six months.
Buy-ins on the games listed today ran from $35 to $50, with pots between $600 and $6,160. Your upside is funded by the players who miss the target.
The number the rules leave out
DietBet’s rules page defines the pot as the sum of all bets, then says it is “distributed to the winners” after “DietBet’s cut.” Read the page end to end and you still will not find the size of that cut. You can know the buy-in and the pot and still not know what share of your own money you are playing for.
Two things worth knowing before you join
Winnings arrive as Points in your DietBet account rather than as cash in your bank.
The rules ban binging, purging and excessive dehydration, and a player ejected for any of them gets no refund. That is a sensible rule, and it is also a reminder of what a weight-loss wager can push people toward.
