Unless you're spending all your waking hours maximally, the time savings of not-cooking versus cooking is not a well-considered trade off in the GPs post.

Just the transit time for a meal out is already going to cost them a great deal more productive time than cooking would. They don't mention Soylent or frozen meals, which are really the only viable way to spend your time more productively than either meal prep or eating out.
