Fitness influencers, trainers, and models show us what's inside their fridges - and reveal why you should avoid 'fat-free' foods and 'cheat days'

January is nearly over, and many of us will have at least attempted to start 2018 with a healthy new lifestyle.

However, if you've found yourself lacking in inspiration or have fallen off the wagon, help is at hand.

Wren Kitchens teamed up with a group of seven fitness influencers - including a Barry's Bootcamp trainer, a dancer, and a model - to find out how they're staying fit and healthy in 2018 - and they shared a peek inside their fridges.

While they each have their own take on healthy living, be it following a strict eating regime or avoiding a restrictive diet altogether, most agree that you should factor in at least one or two plant-based days per week.
