The issue is that humans have extra-ordinary endurance. That just doesn't jibe with modern society. The sub-set of people well-bred to only work out 1-2 hours a day, or to have equilibrium metabolism in a cubicle farms is arbirtary to what would have been bred for genetically. Even the past 10,000 years to about 100 years ago, humans were out and about working physical jobs. And likely going caloric restrictin due to lack of wealth, weather, and other variations of practicality (spoilage, lack of portability, etc). The ability to gorge and store calories is evolutionarily quite useful. But in a sedentary society, lack of balance is not a function of the food, the mined, or even the body. Its rather the lifestyle...cars, cubicles, and costco.
