Meet the expert Kris Murrin Each week the show's expert tackles all areas of the families' lives, looking at their diet, relationships and even their sleeping patterns.

Armed with a masters degree in psychology from Cambridge University, Kris Murrin leaves no stone unturned as she delves into the lives of families in Honey We're Killing the Kids.

As the parents come face to face with the consequences of their children's unhealthy lifestyles, it's up to Kris to help instigate a new approach. Each family is given a set of golden rules to follow for three weeks, which Kris hopes will enable them to get out of their bad habits.

The reality is that a lot of parents haven't been given great information and although they know that lots of chocolate isn't good for children, they've never been shown the implications

"At the end of the day, these aren't bad parents; these are parents who love their children. The reality is that a lot of parents haven't been given great information and although they know that lots of chocolate isn't good for children, they've never been shown the implications. So, when you show the parents where their child's heading, it's a huge shock to every family but also a huge motivation to change," she explains.

Kris is no stranger to tackling the health problems of young people, and is experienced in motivating adults and children alike. She advises the government and private sector organisations on children's issues.

She is also co-author of two books: Sticky Wisdom and What Worries Parents, and has published her own book related to the series, called Honey We're Killing the Kids: The Ten Rules for Happy and Healthy Children. She's married with three children.
