Hello, I am looking for mangas that have characters that eat a lot but don't gain weight or if they do it's not a lot. I would prefer if they weren't like Luffy, Goku or other shounen characters that eat a lot look like they get fat and then look completely normal a little while later. They can be side characters, but I would like them to have a decent amount of panels. Any help is very much appreciated, thank you's very much.
No hentai or yaoi please.

Fushigi Yuugi - the female protagonist likes to eat a LOT. It's one of her quirks (though she's quite annoying)
Full Dozer - Later chapters feature a wonderful female lead who enjoys eating lots of food at different places, but never gains weight. She's also a model.

hmm although this is quite a common trait to make characters funny, nothing really comes to mind. I'll come back if i manage to think up more ^^

Thank you so much. You guys have been a big help

Also Majin Tantei Nougami Neuro
and one of the side characters from SKET dance

Thank you! I heard good things about Majin Tantei Nougami Neuro I will definitely try it out

Toriko - well he does gain muscle though
