I&#x27;m a bit surprised that this article doesn&#x27;t deal with the increasing amount of science behind neurological food reward mechanisms.  The tl;dr is that our junk food (and much mass-produced food in grocery stores) has been tailored for a kind of hyper-palatability that mutes the effectiveness of our normal satiety mechanisms.  So in the article&#x27;s context the &quot;nudge&quot; is up against an evolving attack by industrial food against very low-level neurological mechanisms.<p>I don&#x27;t have a good &quot;lay&quot; source for this field, but I&#x27;d recommend digging into Stephen Guyenet&#x27;s blog[1], that is if you&#x27;re up for wading through an academic&#x27;s professional musings.  He&#x27;s a neurobiologist and obesity researcher, and as such the blog provides his perspectives on ongoing work (his and others&#x27;) in this field.  Warning: DO NOT go here expecting any specific answers, and be able to deal with a fair bit of hypothesizing (i.e. untested, maybe totally wrong) both on Guyenet&#x27;s part and via the work he reviews.  You&#x27;ll only really get a sense of how this field is going as you pick up enough context of ongoing work.  IMO, the most interesting self-contained posts that go by are the significant negative results, where robust work comes to light that just crushes an existing hypothesis.<p>[1] <a href="http:&#x2F;&#x2F;wholehealthsource.blogspot.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;wholehealthsource.blogspot.com&#x2F;</a>
