I am another vegetarian now vegan that became fat. As a matter of fact, I struggled with finding an eating program that would satisfy all the nutritional requirements -- my friends are all trying to get me to switch.
Anyway, I am forced to restrict grains as I found out at the same time as surgery that I have allergies to all grains except buckwheat -- a forced way to restrict my carbs.
If anyone is interested, I have a menu plan that has been "approved" by the nutritionist. I can't figure out how to attach it. If anyone wants it just email me.
