Iceland’s upstart Slimming World is going from strength to strength
Last year’s ranking: 122
Sales: £81.7m (+5.3%)
Unlike beleaguered rival WeightWatchers (97), Iceland’s upstart Slimming World is going from strength to strength. That’s largely down to the premium, world-inspired dishes it has brought out since its launch in 2015, varying from Chicken and Chorizo Paella to Chicken Chow Mein. The £4.1m gain in value is even more impressive considering the emerging competition from Asda, which launched a rival Slimzone brand last year (but had to withdraw any link to Slimming World after a legal wrangle).
