Perhaps you could take a look at the this traditional Okinawan diet, which is 95% plant-based (only a tiny amount of fish). The longest lifespans on the planet (well until the western diet came along and promptly reversed that within mere decades). If you want to talk logically, the most eco friendly approach is a vegan diet simply due to the inefficiency of calorie conversion through an intermediate species as opposed to getting directly from the source.
