No you’ve corrupted the idea of negative association. This is actually a highly successful technique for getting rid of bad habbits and phobias
Negative association can help. For instance a technique in stopping panic attacks invovles the use of the word, “no.” When you get panicky and have racing thoughts, you stop to pattern by saying “No.” Some people will stamp their foot to reinforce this. (It’s not as dumb as it sounds, if anyone asks you just say your foot fell asleep)
If that doesn’t work many people will use a rubber band around the wrist. They say “no” and to reinforce it they snap the band.
The OP’s trying to apply this technique to destroying things.
This isn’t going to work. The idea is to STOP the progression of bad thoughts, not to harm yourself. The bad thought in this case is “I want food”
What you want to do is train your mind to refocus.
Can you build a website? Why not, if you can post in this forum you can learn. So why don’t you go to the library and get a book on XHTML. The point is instead of destroying something when you get the bad thought, you create something.
So what if you try and don’t like it? So what? You failed, big deal people fail every day. How about getting a second job? It’s hard in this economy but let’s say you pick up 8 or ten hours a week and GIVE that money to a charity.
You see involving yourself in life will keep your mind away from food. How about a healthclub? Oh it costs too much. Well how much did the things you destroyed cost you?
Realize what you’re doing isn’t wrong but it’s incorrect. The idea is to STOP the thought with reinforcement. But let’s look at it this way, you can say “stop,” destory something and it may work. Or you can say “stop,” and snap yourself with a rubber band.
Tomorrow you might have a mark on your wrist but you’ll be otherwise OK with the rubber band. With your technique you get a pile of junk. Which by the way you could’ve donated to some poor person who is out of work and would’ve gotten some joy out of it.
Finally losing weight is hard, keeping it off is hard, that is why we’re all not thin. It’s hard. The world’s hard enough without going out of your way to make it more difficult.
Good luck
