Explain Carbs - Fiber pls?

ok, I want to know how to correctly read labels and from what I read online, its always a different way so I want to know once and for all...lol

If I purchase something with 50g of carbs and has 49g of fiber, that means there's only 1g of active carb and I can have that?

TIA

That's what I do. I take carbs and minus fiber and any sugar alcohols because these dont get digested. It's a throw back to my old Atkins days.

Eg. My Quest Bars have 24g carbs, 19g. fiber so it's 5g. net carbs. I only count the 5g.

ETA: I dont know if we SHOULD be doing this or if it changes because of our RNY. I was never told anything different by the dieticians.

Seriously?! I've never heard this! Thanks

 I agree with Simona. The net carbs is what I use to determine if I'm going to eat something or not because the fibre is good for us. 

that's how I do it too (carbs-fibre)

OK - next question - how many carbs should we be having after surgery?  How much fat? 

I am pre-op - but just wondering as I now read the labels, which foods will be acceptable after.

Your center will give you a list.

I used the formula :40% protein, 30% carbs and 30% fats. I tracked my foods on fitday.com
number-wise, my counts were 100-120g protein, up to 50g carbs and I actually don't remember the count for fat off the top of my head. It really depended on what I ate in a day.

Now that I am almost 18months out, I eat almost anything, within reason.

Thank You!
