You'll find it much easier to enjoy eating a healthy, balanced diet if you start thinking positively about it. So stop thinking about the foods you should eat fewer of, like crisps and biscuits, and instead focus on those you can eat plenty of such as fruit and veg, and more low-fat dairy products (like yogurt) and wholegrains. Then start using words to describe them that make them sound delicious, for example, a juicy apple, sweet strawberries or a satisfying slice of wholegrain bread.
