no living being other than Americans has Costco to shop for groceries

go live in the wild for a year with no access to civilization or things like hunting rifles and you will not need to count calories either

resources are never abundant in nature for more than a few weeks at a time in fall ( harvest season ).

why do you think bears sleep through winter ? it's because there is NOTHING to eat.

you don't like counting calories ? try NOT EATING the entire winter.

never speak to me again retard unless you can say something i haven't already heard hundreds of times over the last 10 years of debating the subjects on Twitter with world's most famous doctors, dietitians and gurus.

FUCK OFF
