Could i lose my gut if i jumped rope for a month?

im 16 and last i checked weighed in the 144ish range. but what id like to know is if i could lose my gut within a month by jumping rope. im not really fat in fact people really think im skinny cause my face and arms and legs. but i do have man boobs and a gut. it bothers me to much and its why i dont go swimming.. would maybe an hour a day 10 minutes then rest and so on work if i do it for a month or longer?
