Jackson is not a big breakfast eater, preferring to wait till lunch for her first meal of the day. "I tend to skip eating breakfast and have hot water & lemon, a green juice and a few supplements," she says. "Multivitamins, apple cider vinegar and iron tablets."

Jackson enjoys cauliflower rice bowls with plenty of vegetables for a typical lunch. "When it comes to nutrition, cauliflower is a superstar," says Caitlin Terpstra RD. "It's high in vitamins C and K, and is also a good source of folate, which supports cell growth and is essential during pregnancy. Cauliflower is fat-free and cholesterol-free. And it's low in sodium. A one-cup serving contains only 25 calories, 5 grams of carbohydrates and 2 grams of dietary fiber."

Jackson's go-to dinner is light and nutritious. "Homemade soup (tonight it's carrot & ginger) and some sort of veggie stew or pea pasta followed by berries with coconut yogurt and agave," she says. "Eating vegetables provides health benefits. People who eat fruits and vegetables as part of an overall healthy diet are likely to have a reduced risk of some diseases," says MyPlate.gov. "Vegetables provide nutrients vital for the health and maintenance of the body."

Jackson avoids eating too late in the day. "I like to keep it light and I try to eat before 7:00 pm," she says. "If I feel hungry in between meals I munch a few almonds and bananas. Sunday is a pig out day for me and I love to eat too much of anything I love! My tummy stays relatively flat and firm without much effort. I think that's to do with horse riding from a very young age, and the posture you have to always maintain."

Jackson makes sure the day ends on a calm, relaxing note. "After I put [son] AJ to bed I pop on a facemask and have a long bath before putting on my Milk Makeup vegan milk moisturizing body cream, which is so thick and luxurious," she says. "Then I do my 20-minute evening meditation. It's so important for me to get that final meditation in, because it calms my mind and helps me sleep. Then [husband] George and I will have a light bite and watch a film in bed."
