I eat three home-cooked meals a day, all prepared in advance. My ethos is to stay away from unsustainable low-calorie diets and aim for something balanced: loads of veg, protein and enjoy the carbs you love. Be realistic. I don't count sugar or salt or grams of fat: it's very restrictive and unenjoyable.
I don't come from a very ambitious family. We weren't entrepreneurial. We weren't hard-working academics, or setting up businesses. But for some reason, when I started doing fitness, I always had this voice in my head telling me to keep going - keep going, and people will eventually follow.
My top tips for deep sleep are to switch off your laptop and mobile at least 30 minutes before bed and leave them in another room. Ditch the bedroom TV; listen to music instead. Get a comfortable eye mask. It takes getting used to, but trust me, it will allow you to sleep deeper and longer.
