One of Chatfield's go-to breakfasts is smashed avocado on corn thins. "Avocados are an excellent source of monounsaturated fat and vitamin E, and are a good source of folate," says registered nutritionist Jo Lewin. "They also supply more soluble fiber than other fruit and contain a number of useful minerals including iron, copper and potassium."

Chatfield enjoys salmon and vegetables for a healthy, protein-powered lunch. "We've long been told that fish is 'brain food', and there's convincing evidence to support this," Lewin says. "Studies suggest regular consumption reduces age-related brain loss and may improve memory – it's the omega-3 fatty acids that are responsible for this. Studies investigating the role fatty varieties of fish play have seen benefits for conditions like Alzheimer's disease, depression and multiple sclerosis."

Chatfield likes to eat vegetarian burgers or falafel wraps for dinner. "I would recommend baking it when you have the option," says Amy Shapiro, RD. "If frying is what you prefer, then use a high-quality oil that can sustain high heat, like grapeseed or avocado, to prevent carcinogen production."

Chatfield works out consistently, and likes to incorporate a variety of different exercises into her routine. She takes one day off as a rest day, but the other six days finds her very active. "I work out six days a week with a mix of HIIT, yoga, Pilates and just going for a run," she says.

Peanut butter and dates are Chatfield's go-to sweet treat. "Dates are a rich source of protective plant compounds which have antioxidant properties," says registered nutritionist Nicola Shubrook. "These include polyphenols, carotenoids and lignans, which have been shown to help manage the risk of chronic disease. Research into fiber continues to support its important role in health, from helping to maintain a healthy gut microbiome to reducing the risk of certain long-term health conditions. A small 2015 study found that date consumption may reduce colon cancer thanks to its high fiber and polyphenol content, the latter also having useful antimicrobial benefits."
