Vegetarian( faster slim) sim will stick to veggi dishes, wont eat meat on auto (not sure if fish is ok), will get sick/uncomfortable when eating meat.
Omnivore= eats all, prefers meat dishes on auto(increases fat gain perhaps?)
Off grid trait 1 something like increased handiness, fishing and gardening gains in 1
Off grid trait 2 Increased food quality or skill gains on BBQ/stoves for off grid (to counter the 1 locked lot trait for off the grid)
