Hi Flightbag,

You might want to read the "Which low-carb plan is right for me?" link on the right side of the screen and see some features of the different LC plans out there.

Off the top of my head, the Schwarzbein program allows you to eat those foods you mentioned (barley, yogurt, and oatmeal). It's emphasis is on natural foods, low to moderate carbs. It might be just the ticket for you! They have a sub-forum here and many of the people who follow TSP might be able to offer you more advice.

hth,
Pokey One
