Is there a thing as too much fiber?

[jjw]

I decided to follow some more orthodox rules of fasting for lent. I am not cutting calories since I finished a cut about a month ago and at least I think I a couple of months or so at maintenance plus then might cut again if I need to. Essentially it is a plant based diet no meat or dairy until after Easter. The issue is to limit soy intake it takes a lot of fiber to hit a protein target of 1 gram per 1 lb of lean mass. After the first week or so the digestive system is adjusting. It was a little rough the first week with the digestive effects but have found a way to stay in the 70 to 80 grams of fiber range when I way over did it getting 100+ grams in the first week or so.

Should there be any concerns as to too much fiber? This isn't long term since it is really only about a month and half. Still the lessons learned here are that I can get my protein in and hit fiber targets easier when i go back to normal by mixing in some more plant sources. I was just curious if there is a thing as too much fiber even if my body seems to be adjusting for the most part. More fiber is usually better but is there a thing as too much?

Not really any health concerns per se', but the change in dietary pattern can cause GI symptoms until you adjust. Some individuals are taking >100g fiber/day to help normalize their lipid panel, for example.

Whoa! What foods and quantities constitute this >100g fibre diet? To me, that sounds like a very difficult thing to achieve without consuming a lot of calories or supplementation.

Many vegan and vegetarian options have lots of fiber in them, but one could get 100g+ of fiber with lots of legumes, vegetables, fruits, and whole grains without blowing the Calories out of the water. That said, most non-vegan people going > 60g/day without eating > 2500 Cal/day are likely supplementing with some sort of fiber.
