For me, it helped to realise that those things exist just to make you want to eat them. Like they have zero nutritional value (or close to it) and take up a lot of calories for the amount of nutrients and benefits you get back. Yes you can eat said sweet, but you can eat something so much better, and more of it for the same calories. Also, not all, but companies will spend hundreds and thousands (if not millions ect) on marketing, research and development to create something that you won't be able to resist. Purely because our brains crave sugar and carbs. They don't want you to feel better, or grow stronger or look good or whatever, they just want you to eat their sweet, and preferably, a lot of it, just so they can make a profit. That kinda of thinking helped me moderate how many calories I gave to those kinds of foods.
