The width of the palm could change, but just a little. Feel between your thumb and index, then on the outer side of your hand. There's probably thick, muscular stuff. This will, maybe, reduce in size. Some people reposrt that it changes the appearance of their hands positively a little.
Also, some say the veins on their hands become less apparent, which is good, I guess. Fingers also become a little bit thinner, all due to muscular change.
Overall, I've rarely ever seen people truly impresed in hand changes, as they are minor and sometimes absent, but in some cases, it does make a difference.
Btw, what's those measurements for your weight? Doesn't tell me anything. o.o
