&gt;Obesity is peoples&#x27; fault in the same way car accidents are. That doesn&#x27;t mean the proper response is to simply blame people, instead of using science to devise solutions. &#x2F;&#x2F;<p>But if obesity is primarily the fault of the person who is obese lacking will power then shouldn&#x27;t we start by doing things directly addressing this.<p>For example, I snack late at night - except when there are no snacks in the house. Sometimes I&#x27;ll still make food, but mainly I&#x27;ll just wander around feeling tetchy and eventually get distracted enough to not think about it. For me it absolutely is lack of willpower (which is much better recently probably due to antidepressant meds) to avoid eating things I know aren&#x27;t healthy for me; or indeed just to eat less in general.<p>If we&#x27;re looking to prime cause then for me willpower seemingly fits the bill, as you say that revelation may not help to fix things for me - if I can do outdoor pursuits for a week then I can lose weight no problems! - but healthcare workers looking to help me should perhaps seek ways to enforce diet that don&#x27;t rely on my willpower so much rather than just ignore willpower deficiency altogether?
