I just calculated my maintenance by multiplying my weight by 15*90% as per Lyle web version of what he has in the book. In the book he has a table.
Just doing 15*165.1 gives me 2477 so that's 277 more than I am currently eating. That does seem like a reasonable increase.
I get most of my carbs from veg/beans etc so they come with a fair bit of fiber. I'll eat a bit more junkier stuff.
