Why does he think he can talk to me this way?

Asked husband if I should make popcorn while I was relaxing in the living room and he’s in the kitchen. He said he would make it for me if I was doing his style of workouts where he burns 1,000 calories at the gym. I am unable to attend this gym anymore because I have back issues and I’m going to therapy for it weekly. I still do exercise very much at the gym at least 5 times a week and eat very very healthy. Whenever he makes these comments I get so upset. We got into a fight before and he decides to make rude comments towards me. I am in no way fat! I’m 125 pounds and I don’t need to justify eating popcorn when he literally doesn’t allow speck of food for me because he eats everything then complains about what I want to eat. How do I put him in his place!?
