BF wants me to lose weight

So, I've been friends with this guys for 3 years and we decided to start dating a few months ago. 
And, the other day, we were talking about goals we had for one another and he said "I don't wanna sound like a dick, but I think losing a little weight would be good for you." Not that I don't agree with him, and have thought about trying harder to get fit. I just never really set it as a goal. It was always on the back burner. Anyway, he continued on by saying "You know I love you no matter what, and it is totally up to you whether you want to or not but I do think it would be good for you."
I am 5'0" and weight about 140 which is overweight and within the past year I've gone down from 160 lbs, which wasn't really intentional (I also grew an inch which doesn't really matter but I was classified as obese so I'm proud of myself for that) 
Anyway, I guess I just don't know how to feel about this. I want to believe his intentions in telling me were for the best but I just don't know. Opinions?
