DietBet alternatives for UK users (2026)

What DietBet does

The four-week game asks you to lose 4% of your starting weight; a six-month game asks for 10%.
Weigh-ins are checked by a DietBet referee from two photos: you on the scale, and the scale reading next to a word that time-stamps the photo.
DietBet’s fee is 10–25% of the money paid in, depending on the entry amount. Money due to you is paid as points that can be cashed out through PayPal.
The FAQ says players outside the US can join and payments are converted to US dollars, and that games can be withdrawn in a country where local rules change.

Is the target right for you? A percentage chosen by a game may not suit your health, starting point or timescale.

What is the full cost, in pounds, including fees, conversion and any subscription?
