“I was doing intermittent fasting for a while, but I realized that because my schedule is so crazy and I don’t have regularity in life, I can’t stay on that. I’m a yo-yo for food. I’ll be so healthy, where I’m eating only plant-based [foods] and no sugar for a while, and then I’ll go off it and I’m slamming ice cream and eating pizza. It’s just reality. I try to eat food that’s not highly processed, and I’m flexitarian, because I’m mainly vegetarian, but sometimes I need some meat when I feel depleted. I do generally try to keep the sugar and the dairy in check, though, because it ensures I get better sleep.”

“I went to Villa Stéphanie in Baden-Baden in Germany a few years ago, which was incredible. The doctor who runs it, Dr. König, was amazing and it was quite life-changing. He introduced me to intermittent fasting – it’s not something I do every single day, as David and I are very sociable – we like to eat out and I don’t want to say, ‘No, I’m fasting’. But I do it every now and again, and I see the difference in my skin, my eyes are whiter and sparklier, and I have so much more energy. I try not to eat breakfast, then have lunch at 1pm and dinner at 6pm, so it’s not difficult to do, and the energy and focus you get from it is quite incredible. I eat lots of fresh fish, fresh vegetables and salads, but not too much fruit, as it can make you feel quite bloated. I am very disciplined with my eating, but that’s how I find I get the most out of my body. I do eat seeds and nuts, but never fizzy drinks or processed sugar. My treat is a few glasses of red wine, and I love tequila. I do eat carbs, but I keep them to a minimum. I have lots of avocado and really good fats, like salmon. With four children and a job, I work long hours and doing this works for me so I can give 100 percent.”

“I believe in eating the whole egg, not just the white! I grew up in a household where nothing was restricted, so I don’t have any food rules, but if I’m trying to get into shape, I cut out refined sugar and gluten and see very quick results. I’m a big advocate of intermittent fasting – it was great for me after breastfeeding and I feel better and have more energy if I finish eating by 4pm each day. I don’t eat less, just in a more condensed time window.”

“As a Muslim, I fast for Ramadan, but I also like to do smaller fasts throughout the year. It’s the best reset, particularly after traveling a lot. My diet is so different when I’m in Senegal, where it tends to be starch-heavy with fried seafood; whereas, in New York, I stick to juice and salads. When I break any fast, I always make sure I have a balanced meal afterwards, with coconut water to replenish my salts.”

“In the mornings, I have a cup of organic matcha tea with almond milk and collagen powder, and half an avocado. I start power-eating at lunch, which usually consists of a chopped spinach or kale salad with chicken, or fish and pasta. I also snack all afternoon. I keep cauliflower crackers at my desk (not because I’m gluten-free, I just really love the taste of cauliflower), and have bowls of almonds and other nuts everywhere. Trader Joe’s makes these amazing truffle-flavored almonds – they’re my guilty pleasure, along with any variety of spicy chips, as I don’t eat refined sugar or sweets.”

“I’m a bit of a weird eater, as I like to have salad for breakfast and always eat my dinner early, at 5pm or 5.30pm. I’m not an exciting eater, but I love food and I eat quite a bit, except for sugar and pasta.”
