Will i get noticeably fit within 4 months of gym?

So today i came across this Alapuzha gymkhana’s character poster in which sandeep pradap(falimy fame) had made this amazing transformation for the film

So that got me wondering if i can do the same within 4 Months(mentioned on that post) as my physique is almost similar to him (6’0 ,60kg and lean)

Previously i had gone to the gym for two months but there were no visible result(maybe because of the diet as i used to skip breakfast regularly)and had to stop because of studies

This time i swear i am locked in ,I desperately want some change cant be skinny forever
