Exercise after eating could aid weight loss, study findsDate: 05/06/2007 09:12:43

Doing moderate exercise such as cycling after a meal could aid weight loss, a study has found.
According to research conducted by the University of Surrey and Imperial College London, doing exercise after a meal affected hunger levels as well as the amount of food eaten at the next meal.
Levels of hormones produced by the stomach were also affected, the study published in the Journal of Endocrinology found.
The research focused on a group of 12 people who were given identical breakfasts and then divided into two groups - with half of them doing an hour's exercise on an exercise bike and the remainder sitting quietly.
An hour later both groups were allowed to eat as much as they liked from a buffet.
The study found that people who exercised ate 913 kcal as opposed to 762 kcal in the non-exercise group - but took in fewer calories overall.
Dr Denise Robertson, who led the study, said: "In the past we have been concerned that, although exercise burns energy, people subsequently ate more after working out.
"This would cancel out any possible weight reduction effects of exercise.
"Our research found that moderate exercise after a meal may decrease hunger during the exercise itself by increasing the amount of hormones that tell the brain our stomach is full.
"At the next mealtime, when the amount of energy burned through exercise is taken into account, people who had exercised consume fewer calories than those who hadn't.
She said that the next task would be to carry out the study with a larger number of participants but added: "Our research shows that exercise may alter people's appetite to help them lose weight and prevent further weight gain as part of a healthy, balanced lifestyle."
