Eating disorders are part of the “OCD family”. So that’s the first question to ask: Are you adopting new compulsions to try to cope with and control the possibility of experiences or feelings you don’t like? Because that’s OCD, that’s not a treatment, that’s not recovery. That’s the problem, not the solution.
Another thing to remember is that compulsions relieve anxiety… temporarily. You may have heard somebody say they cut out a certain type of food or they started on a regimented supplement program and that’s “helped”. But it totally makes sense that adopting complex supplement or diet regimes would lead to short-term relief from anxiety or relief from the urge to engage in other compulsions. While struggling with OCD, it’s very common to notice that when you start engaging in a particular compulsion more and more, you might not engage in other compulsions as much. And we eat multiple times each day, so if your diet or supplement regime requires lots of time to prepare, that can quickly turn into several chunks of time every day devoted to compulsions. You might not be decreasing time and energy spent on symptoms–you might actually be spending more time and energy (and money).
Eating healthy is a great support for physical and mental health. Eat to fuel doing healthy things. But if you’re trying to use diet to avoid totally natural feelings, and you don’t learn how to handle those feelings in a healthy way regardless of what you’re eating, then you’re going to end up using food (or supplements) as just another compulsion that’s going to cause more of the problems with which you’re struggling.
