My boyfriend keeps telling me to lose weight, is he being too controlling?

He saw a picture of me of two years ago and said "I feel in love with the slimmer you" Ever since then he's been telling to lose weight. I feel like it's only for his benefit. He keeps saying stuff like "I'm afraid once you lose weight men are going to want you" but honestly I look at myself in the mirror and I look healthy. The picture that he saw was when I was not eating enough. I would starve myself and eat until 4 or 6 in the afternoon. What should I do?
