Chocolate giant Mars Inc has launched a “lighter” version of its Twix bar in the UK.

Available from next month, Twix Fino will have a third fewer calories than the standard Twix, while a wafer will replace the biscuit in the original chocolate bar. Twix Fino contains 94 calories per piece.

The 34g bar is priced at GBP0.52 (US$0.81) and will initially be available in small independent retailers and branches of WH Smith, The Co-operative Group, Budgens and Londis across the UK.

Muhammad Karim, senior brand manager at Mars, said: “We have introduced a lighter alternative to the much-loved snack, allowing us to deliver greater choice to Twix fans.”
