Came here to say just that. Used to love fast food, sodas and candy in large amounts too. Then went to a conference and watched a video of myself giving a talk there afterwards. I hated looking like that.

Thus begun my journey of weight loss. 45kg later I can genuinely say that while some part of my brain still asks for garbage food, I genuinely enjoy eating healthy. My entire taste palette changed, too - and I can now taste flavors that were unknown to me due to overdependence on salt and sugar.

Daily walk/jog is a highlight of the day, and whenever I feel like eating garbage foods again, I just have to think about how it makes me feel not just after - just an hour, or two or a day later.
