Since appearing together on season one of The Bachelor New Zealand, Green and Rice have both become proponents of healthier eating, using their social channels to promote a paleo lifestyle.
Earlier this year, Rice released a self-improvement book titled the Lazy Girl's Life to Living a Beautiful Life, which offered advice on food and lifestyle choices.
Green has also extended his interest in healthier living into a business venture, part-owning Riot Foods, which consists of sub-brands Clean Paleo and Poppy and Olive.
Last year, Green appeared in a self-deprecating promotional clip for Clean Paleo in which he introduced an alter ego known as Grandpa Leo.
Riot Foods has been supported by a crowd-funding campaign on Pledgeme, with contributors pledging more than $146,000 so far.
