Answer one question: is this type of joking from your husband relatively new?
If your husband joked around with you like this before you married, then it is this style of humor. That doesn't mean it is funny. He needs to learn that humor at the expense of others is mean. It is NOT funny and you should not "get used to it." He needs to write new jokes. I wrote an article about it here:
Humor that helps or hurts a marriageBut if this type of joking around is new, it means something entirely different. It indicates that he is too cowardly to come out and express how he really feels and he is disguising his true feelings in a joke. Try, without getting angry and defensive, to discuss how he feels about your weight or looks. If he has any suggestions, tell him you are open to hearing them straight out.
If he insists he is only joking, turn the tables on him and tell a few mean jokes of your own and ask how it feels to him. "Wow, last night was over so quick that I'm not sure if I should say thank you or gezunheit. Just joking!" "Maybe your new nickname will be PP or peanut p*nis! Just joking!"
Then, the both of you should sign up for a community class on comedy so you both can come up with new schtick.
