In AA we have members who are members of OA also. Its all replacing one addiction with another. Of course we can stay away, I mean we dont need alcohol to survive. When it comes to food, we have to eat. What I am told is, certain people are allergic to certain type of food. We have to dig into it and see what suits us. Most of the time, people snack unmindfully sitting in front of television and drink soda/pop those carbonated drinks. You may want to look into those areas. You can join Weight Watchers too. The key is to bring in some discipline in what we eat and the amount we take. If your diet includes lot off fries, sweets and soda there is a good chance of obiesity.
