Fed up with what kind of stuff?
Kosher laws (no pork, shellfish, mixing milk with meat, etc.) are based on safety. People back then didn't know enough not to order their porkchops 'rare'. Also, shellfish in the area the Middle East were (and are) susceptible to the "Red Tide", a fatal bacteria.
So, the HJIC's (Head Jews In Charge) figured out the most expedient way to get people to stop eating the stuff that was bad for 'em: GOD SAID!
As far as eating kosher for physique goals, you could do a lot worse. Tons of chicken, beef, etc.
But (and if you haven't figured this out yet, I am one of the Chosen People), life without bacon not life--it's merely survival.
