Want to lose weight but can't [I Want to Lose Weight]

I have tried so many times to lose weight but have never been successful. I know it mainly comes down to cutting out processed food. Not even necessarily portion size because if you're eating healthy whole foods you can eat a ton and have it not be that many calories. But this is what happens. I can eat super healthy, primarily plant based high fiber foods all day. By night time I am hit with powerful cravings for some kind of junk, whether it is sweets or fast food, whatever. I almost always lose to these cravings and cannot seem to overcome them.

Does anyone have any tips for how to overcome this I guess addiction to junky foods?? I think if I could learn how to prevent or overcome the cravings I could start making progress.
