What does it mean when a guy says it'll taste even better after I loose x amount of weight?

There's this guy who goes out of town every blue moon for business-related reasons, and one day, he was having lunch by himself. I said, "All alone?" He was like, "Yeah, I got my salad with my protein shake and sweet tea." I said, "Oh, okay, it looks good," and then he said, "Yeah, it'll taste even better when I lose x amount of weight and body fat." and I don't know what he was aiming for because earlier i had just complimented him and i think i may have made his head big. His mom already remarked that if she could have any daughter-in-law, she would want a daughter-in-law in law like me.

What do you guys think or believe? Ask away and please tell me your thoughts.

Is he flirting or being funny?
