People are fat because of all the little and big things they do on a daily basis. What you eat is the most important thing. How you exercise is next. What you do in your leisure time is important too. In the 70s, I don't recall anyone binge-watching Netflix while sitting on a couch. TV just wasn't that great and there were only a few specific times per day or week that were something you might be interested in. I don't remember many people playing video games for hours at a time. Sure some minority of people did but the games just weren't that fun and anyone that played Pacman on the Atari 2600 knows that. Kids played outside more, and throughout the neighborhood not just in their own back yard. Adults socialized outside more. There was no Facebook to spend hours per day sitting and reading. I don't think the 70s had Amazon.com either so people burned more calories walking through stores. I distinctly remember shopping with my parents as a kid and it was exhausting walking through a mall for hours. I don't see any evidence the study took any of this technological change into consideration.
