Emma and Matthew (S02E07)

Emma and Matthew, a sister-brother duo from Camberley, Surrey, find themselves in the spotlight this episode. Matthew stays active with weekend mountain biking and hitting the gym three times a week, while Emma limits her weekday calorie intake to just a few hundred. Despite their efforts, they're both gaining weight. Emma's tendency to snack while cooking and Matthew's habit of enjoying chocolate cake right after workouts suggest they might not be as healthy as they think. Once they uncover the surprising truth about their eating habits, will they be able to adopt a healthier diet and work toward a fitter future?
