Kaga is usually shown to as much a glutton as Akagi is, the only difference is that Kaga is usually more well reserved about it. Akagi's gag has gotten to the point where she's eating 24/7 almost. I guess it also helps that Kaga probably gets a bit more romance (xAdmiral) doujins compared to Akagi.
