You do have a point here, but I don&#x27;t think you&#x27;re &quot;spot on&quot; regarding the motives.<p>Although I agree that &quot;the ability to have the cake and eat it&quot; (i.e. the <i>gluttony</i> motive) can be prevalent, I&#x27;d say that the most important factor is the conception of eating, not only as a physiological need, but as a social ritual.<p>My personal experience is that while I can (very) easily restrict calorie intake, I&#x27;m less inclined to do so with friends and colleagues when invited to share meals. Take a &quot;protocol&quot; such as the &quot;Internet-popular&quot; intermittent fasting; if I&#x27;m invited to lunch with colleagues and if my girlfriend wants to have dinner somewhere, my fasting period for the day will be seriously harder to achieve. I could juggle with the scheduled hours for the meals, but then I&#x27;d be &quot;imposing&quot;. It&#x27;s doable, but not something I actually want. I don&#x27;t share that many meals, so I can be compliant with my diet; but this is just not true for many people.
