“Nobody is born extremely obese,
they acheive that by overeating & not exercising daily.
People who are overweight, just get over it & please go
on a SERIOUS diet.”
there is clearly a quite powerful genetic component to obesity.
it existed in olden times of poverty as well.
Reb Eliezer ben Shimon was known to be massively obese.
it was said (although probably with some exaggeration), when he and another Godol (forgot his name) would stand facing each other a wagon could pass under the arch formed by their bellies. do you think they got that way because of eating desires and overeating?
