If you go to the Starting Strength forum there's a sub-forum on nutrition. The guy who answers all the questions, Jordan, is very much for eating paleo or similar and doesn't push the GOMAD as much as Rip does, especially if you are trying to go from fat to muscular. The whole GOMAD thing is for young weaklings trying to go out for high school football.
And the 45lb bar is too much for some women, especially with the whole warm-up scheme you are supposed to do. Not everyone can raise 45lbs over their head with no experience. Even after lifting since October I can still only get about 55lbs over my head.
