I have problems with the word 'Addiction' there. Chips don't have a substance that make them addictive. You can't get addicted to anything, you just like 'em, that's all, it's not like heroin or ...
Take coffee for example, ok, there's caffeine in there, you might be really annoyed if you can't have coffee for an entire day, but you wouldn't pull your hair out and throw up either if you don't have one. You could go on and on and on without any problems at all, you'd just get used not to have coffee.
I'd say the best method is to go cold turkey, that's what I would do. If that sounds too harsh, then just have a very tiny portion of chips once in a while, 2-3 chips, not half the bag, takes will power to stop, sure. That won't hurt you too much and you'll still get to taste the precious chips.
Chips aren't really "Food" anyway, hardly any
nutrients, nothing that is good for you in there.
It shouldn't even be called 'Food',
If you are not ready to quit eating bad food like that, it seems like you are bound to have a very tough time, if you're really sincere about losing weight than it shouldn't be a problem to start eating good food, not things like chips that have so much calories, fat, sodium and don't give you much energy either.
When I see CHIPS at the grocery store I am not even tempted to grab a bag because I know they aren't good for me, I haven't had a chip in months, I'd rather eat good healthy food now.
Cheers !
