Carrot Top -- My Buff Days Are OVER!!!!

Carrot Top is sick of being compared to a ginger Arnold Schwarzenegger ... telling TMZ he's dropped 30 pounds in an effort to return to physical normalcy.

C.T. was at Boa in Hollywood last night ... when he told us he's given up weight lifting for the time being to focus on cardio so he can shed the diesel muscle mass.

When asked if he was sick of being buff, Mr. Top replied, "It didn't fit my style."

FYI -- here's Carrot back in 2008 (below) ... so ... yeah, we approve of the new look.
