It's a validation/affirmation thing. You ever see the people who make plans to start working out? Super detailed, all the newest fad shit thrown in? It's because the planning gets the mental reward. Actually doing it give you the physical/'real' payoff, but takes so long that these fucktards never get it.  The same way, telling others you got weight loss surgery or are starting a diet gets all the attention and affirmation, in the short run. That's all they care about, so off they go, telling you for the umpteenth time that they're on a diet! Aren't you happy/proud, shitlord?
