Thanks for the response! Still, I wonder what we as society get so wrong. People used to eat whatever they wanted (and was available) whenever they wanted and not be fat. I recently watched the original woodstock 69 footage. There are zero fat people there. For all I know it may have nothing to do with eating.

There's a big difference between "eating when you want" and having an active lifestyle that restricts eating naturally, versus binging TV on the couch with junk food 10 feed away.

Conclusion

Over the last 50 years in the U.S. we estimate that daily occupation-related energy expenditure has decreased by more than 100 calories, and this reduction in energy expenditure accounts for a significant portion of the increase in mean U.S. body weights for women and men

That's 3000 calories per month, or almost 10 lbs of fat per year.
