On high fat, high carb, low protein diet -> very likely.

You should realize that these kids probably are not doing LC - they
simply eat too much both carbs and fat....

 What does this have to do with the above?  The point is that children
eating low-fat diets are fatter than those on medium-fat diets.
Neither group, as far as I know, slops hogs, milks cows, etc.

I think it has more to do with the fact that most children don't have
to get up  in the morning, slop the hogs, milk the cows, fetch pails
of water, get the firewood and stoke the stove any more.  Then walk a
mile to school, walk a mile back, then help weed the garden, plant the
seedlings, pick the eggs, and pickle the produce.  Hell, even city
kids had to walk everywhere just a few decades back.  My childhood
skinniness was almost certainly due to my chore load and walking
everywhere.  I certainly didn't give a rats a.s what I ate until I
started sitting on my butt all day.

I agree with your comments above being a city kid whose parents could
not afford bus tickets and had to walk 1 1/2 miles to school and then
back home. We also did not have a computer or computer games, a game
boy or nintendo box, and we had to do sports at lunch time in school.
Have parents overcompensated due to pedophiles and kidnappings? BTW,
it is cheaper to eat at McDonald's in the States than it is in Canada
but we are slowly getting there.
