Mathews shared some of her health tips to Red Online. She says that she is working on reducing negative thoughts. "For every good intention, there seems to be a voice in our heads that wants to cause trouble. For me, I kept thinking that there was really no point in even trying to change the way I ate so why even bother? That kind of thinking is negative and counter-productive. Try and drown out those thoughts with more positive thoughts. You CAN do this."

Mathews tells Red Online that she made small changes to her lifestyle over the years. "The most important thing though is not really how you look, but how you feel," she explains. "I found that the little changes I made over time made me feel good about myself and eventually showed on my body. So be patient and wait for results before just writing yourself off."

Mathews tells Red Online that she likes to make smoothies each morning. "In the mornings, I was leaving myself short of time and so I was going out on an empty stomach and then just grabbing anything for lunch as my blood sugar dipped. Giving myself an extra 10 minutes in the morning left me with just enough time to make something substantial. I started making smoothies using frozen spinach, frozen raspberries, apricot kernels, flaxseeds, walnuts and water. Drinking a nice thick drink like that keeps you going until lunchtime and so you don't feel the urge to pick at unhealthy food."

Most people take the weekends off from their health routine and re-start on Monday. However, Mathews isn't one of them. "It's a familiar story: after a weekend of excess filled with roast dinners, full English breakfasts and Chinese takeaways, we feel guilty and want to start eating healthy," she explains to Red Online. "I would advise against starting on a Monday. Most of us will be heading to work on Monday morning with the Monday blues and dealing with the stresses that come with a workday. I would suggest starting half-way through the week by introducing a small change and following through over the weekend."

Mathews talked about her diet to Express. She says that she makes sure to eat healthy food. "It's all about moderation and what makes you feel good," she says. "If you can invest in a good-quality olive oil or coconut oil, and substitute processed foods for oily fish, walnuts and seeds such as flax seeds rich in omega-3 – you will feel the benefits."
