For 1400 calories, I think about 175 total grams of carbs is correct. I based this on the guidelines suggesting that 50% of calories come from carbs, and there are 4 calories per carb/gram...SO: 1400 divided by 2=700. 700 divided by 4=175. The thing to remember is that "complex" carbs like whole grain, veggies and beans have FIBER, which most "simple" carbs like sugar, white bread, cakes, soda, etc. DON'T have any fiber so they spike blood sugar. I also think that you can deduct the fiber grams from the carb grams because fiber is not digested by the body (that's where you'll see the term "net carbs" on packaging). So if a whole grain roll has 20 g of carbs and 8 g of fiber, you really only absorb 12 g of carbs. Hope this helps!
