A day in the life of Instagram superstar and clean eating queen Deliciously Ella

At the age of 25, Ella Mills has nearly a million Instagram followers and a blog that has seen over 100 million hits since its launch in 2012.

She operates two delis and a festive food pop-up in London, has her own brand of snacks in retailers like Waitrose and Starbucks, and a number one food and drink app. If that wasn't enough, she is about to launch her third cookbook. Her first was the fastest-selling debut cookbook ever in the UK.

So who is this unstoppable, brunette force of nature? You will likely know her as Deliciously Ella, the smiling face at the front of the clean, green, plant-based eating trend - and the woman behind t-shirts that read "Peace, Love & Kale."

But after spending some time with Ella and her husband and business partner Matthew Mills, Business Insider discovered there is much more to the health food advocate than leafy greens. We followed the Mills couple for a day to see what it's really like to be Deliciously Ella.
