I am very clear when I order out, not rude, but explain myself very well. I always order a steak, safest and most filling for me. I am ask that no sauce or spices me used on my steak either, that I have food allergies. Yes, I do get strange looks, but there are also not a lot of almost 40 year old moms who look as good as me either. So, which would I rather? I few strange looks and comments or my new amazing body and perfect health?
No one questions a vegeatarian when they make their meal order and are very specific, so I feel I have the same right.
Now, the first few times you eat only meat in front of others, it is weird, but after a while people get used to it and you get used to it too.
