The Rocks diet

So I just checked out the Rocks diet. Doesn't plug any products so I think its legit.
It obviously works for him and i know were all different, but wouldn't eating 7 full meals take its toll on his organs especially as they are all meat heavy? Its so contradictory to Nick Diaz's diet for instance.

2 whole eggs
2 cups oatmeal

Meal 2

8 oz cod
12 oz sweet potato
1 cup veggies

Meal 3

2 cups white rice
1 cup veggies

Meal 4

8 oz cod
2 cups rice
1 cup veggies

10 oz cod
2 cups rice
