Lesley McKenna: "Eat wholesome food that makes you feel better. And do yoga." Robbie Renwick: "What I find helps is having quite a bit of protein in the morning, such as boiled eggs. That can offset hunger until lunchtime. If you skip breakfast you'll find by 10.30 you want to snack on chocolate bars. It's being aware of what you eat. Carbohydrates are the devil. If you are doing no exercise at all, stay away from biscuits and sugary drinks."
