Are you talking about 4 exchanges of starches/bread per meal? Each exchange is 15g carbs, so 14 per day is 210g of carbs per day. And my recollection is that fruit is a separate exchange with something like 3 fruit exchanges on the 1800 cal diet. Each fruit exchange is also 15g carbs.

If this is the diet she put you on, well, it is not a low carb diet.
