A famous author once made the following observation - When faced with the option of either doing more exercise or less eating for losing weight, take the option which requires you to a) spend less time and b) not add anything new to your life (i.e. the cognitive overhead).
Apparently, people who tried to eat less were also more successful in losing weight.
Cutting off home internet is the option of less eating. Seems more drastic, but is actually more tuned to how our brains work.
Your suggestion is similar to doing more exercise. It can also work, but it is just a whole lot more work and cognitive overhead.
Besides, its not like the author is asking people to go off the grid.
To be fair, the amount of exercise you need to overcome even small amounts of excessive eating can be disproportionately difficult and time consuming—but while the example may have some logistic holes, I still generally agree with your idea :)
