Quote: I'm not a nutritionist, but I do know that men are supposed to get the upper recommended limit of fiber (closer to 35 grams than 25 grams) because their caloric intake is higher than women. And like I said, if you eat a lot of meat, you will need to eat fiber to offset that. Meat has no fiber in it whatsoever(SF or IF) and will just sit in your colon without fiber to push it out.
We still can't tell you if parts of your diet is IBS safe or not because you haven't answered some of our questions. What are the ingredients in your supplements in your shakes? Do you know for a fact that you are ok with soy protein in your Builder's Bars? Some are not able to eat it.
And like a number of people have told you now, you need to add more IF to your diet in the form of fruits and veggies.
