Do you have a rail of clothes in your wardrobe that used to fit and you're hoping it won't be long before you're back into them? Send them to a charity shop right now! Whilst you may believe that seeing these clothes will serve as a reminder of the size you 'could be', they will actually just limit your ability to feel happy about yourself right now, as you are.
If any lasting change is going to happen that brings about weight loss, it won't be through reminding yourself constantly how unhappy you are with your current weight, by seeing clothes that don't fit hanging in your wardrobe all the time. Self-acceptance and loving yourself whatever shape or size you are is key to any changes that might happen regarding your improved relationship with food.
