Ever since her rebirth, Su Xiaofei was trying to change her eating patterns and to stop restricting herself to only eating salads and vegetables to control her weight. She had considered doing exercise, but she was at a loss in the beginning as she didn't know where to start.
When she asked Lu Qingfeng's opinion about it, he told her that the key to weight loss was to consume less calories than she had burned. For most people, it was easier to lower calorie intake to a greater degree than it is to burn more calories through increased exercise.
Lu Qingfeng claimed that cutting calories through dietary changes was generally more effective for weight loss. But doing both — cutting calories through diet and burning calories through exercise — can help give her the weight-loss edge.
