weight jump help

Hey. Had my 24 wk prenatal today. Everything went well. But I have gained 10lbs since my 20 wk appt😔 I know a few of those lbs prob had to do with Christmas dinner and leftovers and chugging water before appt but that's certainly a jump. OB said not a problem that it's fluid and not much can be done about it. Here's the thing, I have 15 wks left and don't want to gain too much weight. I was at higher end of normal weight prepregnancy. I'm 24 wks and have now gained 22lbs so far. The only diff lately is I had basically be vegetarian but lately have been eating meat lately. Suggestions please
