Emily makes sure to hydrate. "I'm really good with my water now," she told HELLO! "I try and drink two litres of water a day." This translates to about a half-gallon, which is generally recommended by health experts for the average person. According to the Mayo Clinic, hydration is important for a variety of reasons. Water helps get rid of waste through urination, perspiration, and bowel movements, keeps your temperature normal, lubricates and cushions joints, and helps protect sensitive tissues.

"I do try and keep quite healthy – because I love alcohol, I have to balance it out a bit! I can't be eating bags of chips if I'm having wine," Emily told Hello, adding that she loves a glass of wine with a meal. "I like white wine, I like red wine, I like rose wine, I like dessert wine, I drink everything! All the wine!" 

Emily is a fan of intermittent fasting. She eats her first meal around noon. I don't have breakfast – I'm not a morning person – and I'll eat my first meal, usually a chicken salad, around midday,' she explains. 'Mid-afternoon, I'll have a snack, and then another meal early evening, which is normally a pasta-based dish or a HelloFresh delivery if I'm busy. And if I want dark chocolate, popcorn or my favorite pad thai takeaway, I won't deny myself," she told Women's Health.

"Food for me… there is no such thing as a guilty pleasure, it's all just pleasure. It should never be guilty," Emily dished to Hello about her approach to cheat meals. "In the week, I'll snack on things like cashew nuts and fruit. I'll have a banana. If I'm sitting there and craving something sweet I'll have a bit of dark chocolate, and I always have an emergency tub of ice cream," she said. "At the weekends I pretty much eat what I want. I save all the naughty stuff like crisps for the weekend." She added: "I'm in my 30s now. I can't get away with having pizza takeaways three times a week! And I'm certainly not one of those people that runs marathons. I'm not athletic in any way, so I need to keep a good balance."

Emily exercises her body and mind. "I'm quite spiritual. I believe in positive energy and manifestation – that what you put out into the universe, you get back," she told Women's Health.
