19. Part of it is to stop seeing food as a pleasure or part of a reward system.
There are other pleasures in life. Not trying to sound smarmy, just pointing out that if you see food as more of a mechanical necessity instead of a 'pleasure', that's a good first step to ridding yourself of the 'allure' of food.
It's a mindset as much as anything else. 'Embrace the hunger' has been my motto. That doesn't mean starve yourself or take chances with your health if you have any cardiovascular conditions, it means seeing hunger -when you KNOW you aren't going to starve to death or collapse- as a good thing.
