This is a good summary however I believe part of the issue is that due to high intensity farming the mineral levels of the soil are way down thus mineral levels of the foods we eat are basically nonexistent. People are hungry all the time because they are, essentially, malnourished. The body needs many different trace minerals to function well and if it doesn’t get it will be hungry.
A fat man can be fat and malnourished at the same time. Truly a first world problem.
Why has the percentage of the population that are obese or overweight increased so much in the US?
