In terms of diet, you can choose foods with less calories and large volume, such as vegetables, melons and fruits, and pasta. Change bad habits, eat less snacks at ordinary times, don't eat supper and cream cake before going to bed, limit the intake of oil and sugar, and prevent excessive calories and obesity. It is worth reminding that while reasonably arranging diet, we should also strengthen sports and physical exercise, such as running, swimming and skipping rope. However, the amount of activity should not be too large, and strenuous activity will increase appetite.
