I dont think feeding every other day is starving any fish.
To be fair, the feeding will differ where you are. I'm in the tropics and the tanks, even unheated, sit in the 80's all summer. So the goldfish are very active and always hungry.
No fish actually has to eat every day and it's not starving them if they don't, but I do feel there is an attitude out there that reducing food intake on fish is just a way to cope with an inadequate tank size or filtration system. That was more my point here.
