Rin has many reasons to be heavier than Haru.

1.He's taller than Haru

2.He does muscle building and training everyday. Muscles generally makes your weight scale higher. (this is probably the most probable reason for his weight)

As for Rei

1.He's taller than Haru. He is 2cm taller than Haru in his third year of highschool, compare to Haru's height in his third year of highschool. They're weight came from that time.

2. He used to be in a track club so probably built more muscles elsewhere (i'm not really too confident of this reason)

3. He probably just eats more (since Haru always eats mackerel) they're diet is just different.
