it dose not go up to 25%, i would say at the most 15%. the extra weight is water not fat. and yes you have to eat to grow, thats why lee has got elegidly 20' arms and he is probably the shortest pro.
I have seen an off season pic of Lee ...that if it didn't have his name below the caption...you would wonder who the hell the pic of the fat pig was .....but he does have the best arms on earth!
I read in an article in flex that his doctor told him he had something wrong with his heart....but he competed anyways.....he's a damn machine I tell ya.....and his arms are fucking huge!!!!!
I saw a picture of that freakin freak in flex a few years back, and they had a picture of him crushing a full soda can (unopened) in his hand like and egg and making soda shoot out like a super soaker. Thats some fucking forearm power. HAHAHA.
