Societies with easy access to calories and sugar/carbs/sat fats and reduction in movement and increase in sitting have more obesity, right?
I am doubtful that easy access to calories means more obesity. The Japanese is a wealthy society and is less obese than the American, for example.
Also, societies that move more doesn't necessary have an increase in TDEE as society that move less. Your basal metabolism adjusts and accounts for physical activities. you would probably need to go to extreme to adjust your TDEE upward.
I’m sure there are cultural and genetic components also, but you can simply compare parents and their children over the past few decades in countries with obesity problems to control for some of that.
