Niall Crowley, 31, and Marcus Price, 33, started EatEvolve, which delivers ready-made “Paleo meals†to customers’ doors, last year.
Followers of the so-called caveman diet avoid foods such as dairy, grains and refined sugar. Instead they eat organic meat, seafood, eggs, leafy vegetables and fruit in a diet resembling that of humans in the Palaeolithic era, around 3 million to 14,000 years ago.
The co-founders, who are childhood friends from Ireland, came up with the idea as they struggled to eat well while balancing busy working lives. They offered dishes to fellow gym members and rolled out the service following an “overwhelmingly positive†response. Today they deliver around 6,000 dishes a month to clients including Made in Chelsea’s Oliver Proudlock and Caggie Dunlop.
Mr Crowley and Mr Price say Ms Mackintosh, 25, who also starred on the reality TV show, used the service before marrying rapper Professor Green last year. Each of the EatEvolve dishes, which cost 60 for five, were developed by chefs including Nurdin Topham, who was trained by Raymond Blanc, and Mark Broadbent, the former head chef at Bluebird in Chelsea.
Tasty platter: One of the Paleo dishes Mr Crowley, who gave up his job as a property financier in the City to concentrate on EatEvolve, said: “We have been bowled over by the response. There are so many people who are too busy to cook but want to eat well.
“Celebrities have made it cool to care about your health and we are feeling that influence. People care more about what goes into their food following horse meat and other scandals.â€
Mira Griffiths, 28, and her partner Pete Cookson, 36, run PaleoChef, another London delivery service. Customers sign up for five-day meal plans costing between 120 and 150.
All are hand-cooked by Mr Cookson and delivered by the couple to about 38 regular customers across London every Sunday night.
Ms Griffiths said people were more educated about the risks of lifestyle diseases and “cared more than ever†about their health.
She added: “The feedback I am getting from my clients is that it feels like a natural way of eating. People enjoy their food and don’t feel deprived.
“They are not calorie counting and starving themselves. It’s a nutrient-dense, healthy way of eating and the benefits are obvious.â€
Over the past few years, the “caveman diet†has swept America, but it is still relatively new to the UK.
London’s first Paleo restaurant, Pure Taste, has started taking bookings ahead of its opening next month.
