Is Will every man will detest think his wife is out of shape after she has a baby?

My boy is 6 months old now, and my husband often tells me that I am so very fat, I am so sad, I don't want to be fat too. But when I try my best to lose my weight, he tells me again that he doesn't want me to lose weight, and he says he likes me as how I am now!
I am confused now, does he say I am fat just kidding with me is is he kidding when he says I'm fat? Does he really not like me being fat? Is Does every man will detest not like his wife when she is out of shape? What should I do now?
