Is it bad that I keep food out of my house because I would overeat otherwise?
Why don't you just just eat what's in the house and what's expected?
I don't want to take a chance, so I buy my food every day.
People will go to extremes especially when they want to maintain their weight. Maintaining a healthy diet is to be expected, you should learn to maintain a healthy diet without having to keep food out of the house. Continuing this odd practice of having no food in the house may not help you in the long run when you need to have food in the house.
I can't eat healthy. It doesn't work for me.
There has to be a way you can get it done but  I guess as long as you are eating healthy it's better than nothing.
