This special edition looks at how such a daunting task need not be that hard.

Kate Quilton travels to Australia to find out if veg and fruit can replace carbs and meat to cut calories.

Helen Lawal talks to those who have been on long-term diets, Jimmy Doherty looks at the best food for endurance training, and Matt Tebbutt wonders if any drink will make him look younger.
