Nope. Constant access to food and water would make them even more powerful since they could push themselves more in training and not having to worry about being starved or something like that.Huh, but won't the future heroes be weaker then if they have easier access to food and water or will they always face a hard training to be on the same physical and mental level as Aeolos was?
For comparison, look at the pictures of modern day US soldiers and their WWII predecessors.
