Actually, eating whatever you want does not imply you’re truly letting go of being a restrictive food zealot. You could want to eat only fruits, vegetables, and other “healthy” foods. You could convince yourself that that’s what you want because of X, Y, or Z; losing weight, becoming more healthy, living longer, preventing cancer, etc. And that’s not difficult to do; it’s not difficult to want to be thin or any of those other things which are often the root cause of wanting to eat only “clean” or “pure” foods (orthorexia) or eat less.
What you really need to do if you want to restore sanity into your diet and lifestyle is to deliberately eat foods that you thought were “unhealthy” and now condition yourself to think it is healthy. It is healthy because it will do X, Y, and Z. Some potential reasons are: improve immunity, strengthen bones, improve fertility, restore curves to the body (female), strengthen erections, improve mood, increase mental acuity, improve metabolic rate (Matt Stone style), warm hands and feet, free yourself psychologically, be more social, enjoy food more, relax, etc.
In order to do this you have to just put it in your mouth (PIIYM). This soda below I discovered recently for example is something that you may want to put in your mouth. Not everyone likes herby sodas but wow I do.
But do you need to put really bad things into your mouth? No. You don’t need to eat a McDonald’s burger that is made with soybean oil. But psychologically it will help, because that’s really the same argument for not putting anything you perceive as being “bad” into your mouth. Have I eaten McDonald’s? No but I make burgers myself and love bbq sauce. Just keep in mind that the suggestion I made here doesn’t apply to everyone with disordered eating. Anorexia patients are told to eat every few hours to avoid any period of fasting. PIIYM applies though in that scenario.
Talk soon and stay hungry my friends.
