I learned to just tell people I'm allergic to grains and sugar. Everyone understands allergy. They all have allergy to something. People know that they sometimes eat what they are allergic to, just because they want it. So they might ask me politely if I am allowing myself grains or sugar today. So it's all up to me. No one ever presses me anymore. They know or imagine the results of indulging in foods I am sensitive to: foot cramps, face rashes, indigestion. It's nothing about my weight or shape - no one cares about that. You see, in the past if I said I was watching my weight, then they would say just this once won't hurt. However, if you have an allergy, they realize even one bite will hurt. So that is my story. And as far as I am concerned, my body's inability to process grains and sugar is an allergy or even an illness. PS: I do get cramps, indigestion and rashes from these carbs too. Also joint inflammation. So carbs are an all around poison for me.
