Hi
I too am vegetarian, and have had to knock of dairy products as it gives me stomach probs. I know u dont rate the no starch diet (and by writing this post by no means am i havin a go, i am merely chatting to u as a friend regarding my opinions and experiences, sometimes other experiences can provoke food for thought)
Myopinion is certain foods seems to work better for different people, i hope ur dietician can advise u on which foods could work best for u and then u have the desired effect.
By the way, i understand desks jobs can b very sedentary, if ur not too self concious, there are desk exercises.
take care
heather
