I would recommend looking into some nootropics. Certain amino acids can be very effective not only in mood disorders but also with reducing cravings.
Cravings for sweet sugary delicious substances which can drastically exacerbate OCD symptoms.
I've been on antidepressants for a majority ofd my life and I am just now in the process of weening off of them.
Ive been in the pits of OCD hell before and I feel your pain and frustration. So far my process has been going great and Iv'e had reduced cravings by taking 5htp throughout the day.
Warning: There is a disclaimer to not take 5HTP with antidepressants, but my doctor knows about it and he is on speed dial in case of an emergency.
Obviously I'm not a medical professional so talk to your doctor about how to do this if you are on antidepressants.
With respect to the diet, unfortunately you really have to go all in with cutting out all junk food.
Best of luck.
