I too had a food addiction for as long as I could remember. Take it one step at a time. Start weaning yourself off one item at a time leaving tubors for last. I kicked grains first but would still indulge in a burger, but without the bun. Then dairy. I went 2 weeks before I cheated with milk for my coffee and paid the price. Now knowing that if I cheat I'll feel sick for days I no longer have the will to cheat. 6 weeks in and all I eat is animal protein, fruits, veg and tubors. All I need to do now is start limiting my tubor and fruits and increase the veggies.
