My Struggle: Food

I stepped on the scale right after vacation, and I was a bit concerned because I gained weight. Ok, maybe I ate so much food from vacation that I gained 2 kilograms, but it was something I shouldn't ignore. This is a habit I see myself doing. I see a yummy snack in the pantry, which is usually chocolate. Something inside of me gets triggered (no, not being mad triggered). I have a cue that tells me to enter a routine, which is indulging on sweets. The reward I get recently is the satisfying long time it takes to eat a single Pocky stick by slowly nibbling off the chocolate (which you may find relatable or strange).
Despite tracking what I eat, it seems that nothing works, even if I exercise every day. I think I still eat snacks because of the any benefit logical fallacy, which is you try to find any tiny benefit to justify this action, even if the negative sides outweigh the benefits. This term was originally coined by Cal Newport regarding social media, but I think I can apply it on other situations. Let's reexamine my Pocky habit. I probably would say that the benefit of eating it is that if I don't eat it, no one else will eat it and it will expire (this is a common excuse I use). Another justification I would use is that my mouth is bored and I want something to chew on because I miss the sweetness of food.
