Yeah, I agree. I don't think he's necessarily trying to be "subversive" (though I find the point about 'always dieting' to be a little insensitive) -- I think he just loves chocolate, and assumes that others love it as well. Spreading the chocolate love!
The deal I have with my BF is that he can buy any treats he wants, as long as I don't like them too. I'm lucky in that I don't have a big sweet tooth, so there can be cookies and candies around the house; I just don't want them. But if he were to buy, say -- chips, or cheezy crackers, or Doritos, we'd have problems!
I like almeeker's suggestion of "splitting" the boxes, buying you something that he likes himself, etc. Or, instead of saying to him "You just don't understand! I Need This!" try saying something like "I appreciate that you want to do nice things for me, and I love that you're thinking of me, but what I'd really like is..." and then list whatever you'd want, be it flowers or some nice jewelry...or a blender!
Guys can be a little thick-skulled when it comes to presents. Most of the time it's about the gesture, and not the chocolates. I hope you guys come to a nice conclusion and a compromise or solution that works for you.
