The bulk of the book's contents covered ethics regarding how food is produced, it's effects on animals, humans, and the environment. But at the end, the authors touched briefly on our attitudes as we are actually consuming it - the ethics of obesity/overeating.
As an environmentalist and an advocate of voluntary simplicity, I spend a considerable amount of effort minimizing waste, consuming only what I need because I think it's unethical to waste resources just because we can. So when the book presented me with this question: is eating too much unethical?, I really took it to heart.
From an evolutionary perspective, we are wired to eat whatever we can get our hands on, for fear the next meal might be hard to come by. Even in our more recent past, gluttony was considered one of the seven deadly sins. But in modern times (particularly in the US with the food system we have set up), do we even think about it?
From a personal perspective, I often find myself overeating, then getting in some extra work-out time to burn the extra calories off. We all do it, right? But the question is, when we really start to think about it, is that attitude unethical as it relates to wastefulness?
It's a tough question, and if you were within range, you could probably smell the smoke from all the gears turning in my head. What do you think? Is obesity/overeating unethical?
P.S. Keep in mind this is regarding people who have a choice in the matter, not those for whom obesity/overeating is the result of a medical condition...
