Refer to my previous points about number of fat cells, testosterone and T3/T4 levels in the body, of which all of these can and do impact on caloric burn rate and obesity.I'm just saying that according to most medical studies, only leptin seems to have a HUGE effect on the prevalence of obesity. Basic metabolism, on the other hand, doesn't seem to have such a noticeable effect, contrary to most legends.
You've taken a really simplistic approach towards obesity where it's not that simple, never mind the emotional and mental aspects of it. It's quite a complex matter which also surround cultural and socioeconomic influences.
I posted my pic so you'd know that I'm not debating based on self-protectionism.
