Fiber pills

Okay so after some guidance I started taking the fiber pills this week..... They are making me gain weight I think. My diet has been very tight lately typically undr 15 carbs a day right at 60grams of protein.
And these fiber pills are NOT doing their job. Just saying.
Any ideas on what the issue could be. I mean obviously I'm not going so a little weight is understandable but not several lbs

How much are you taking of what?

It's 6 capsules of Metamucil. The recommended dose

You giving it a few days?

 I was told to only have benefiber, cause it's a natural fiber and the nutritionist told me to start on half a dose, then add more.

I was told to only use Benefiber by my surgeon. I purchased the tastless powder and I put it in my protein shake in the morning. It really works! Blessings2u--BJ

I take a magnisium vitamin everyday and it takes care of the constipation.
No calories.
