Last night i said something really stupid

In front of my BFF who is overeight, her whole family is overweight and they are very sensitive about it as they have tried many times to lose weight i said:

“He (someone I know) should be all over that like a fat kid on a smartie” UGH. As soon as i said it i felt like an ass. IDK why i said it. It just slipped out. I’m usually very sensitive to those situations. Should i say/do anything? Apologize?
