You could try saying you are on a strict doctor supervised diet and would appreciate their support. Then, if they push the food, just say "No thank you." You shouldn't have to pretend you are eating/drinking and you shouldn't have to divulge your medical situation. Just be consistent. It is odd you aren't able to eat eggs. I have been on this board for more than 20 months and no one has said eggs are forbidden. From what I can tell, the other nutritionists including mine have said eggs in any form are acceptable at that stage. Oh well.
