Then his cousin dies from health complications due to an improper diet and his sister makes him promise to lose some weight. This is very hard for him, but he finds motivation when he falls in love with Lydia. He spends so much time kissing and walking around with her that he no longer eats as many unhealthy things, and he loses weight without even trying.
