My downfall was my emergency food storage of beef jerky and hard candy and Diet Coke, nuts, granola, etc.
I can't throw it out because, well, throwing it out would defeat the purpose of having emergency storage.
I ended up putting the stuff in an extra closet and locking it with a cable tie. I can't get through it unless I use scissors and kill the zip tie.
It's working.
As for the OP's question, advice like "just don't eat it in the first place" is self-righteous Monday-morning quarterbacking and not productive, mmm kay?
If you see cookies, break off a half a cookie, walk away, and enjoy the heck out the half-cookie. Eat it slowly, savor the taste. Yes, you cheated, but only 1/8 as much. Pat yourself on the back for feeling satisfied with only 1/8 of a cheat. Then later go back and get rid of the cookies.
That said, I am lucky in that I am not easily triggered for carb carvings, so it's easy for me to cheat one meal and not call the day lost. I know a lot of people are not like that. I guess the only thing to do there is to eat the 1/2 cookie and then shovel in some butter or coconut oil and go for a walk. That might trigger a stop signal.
