Bowel Movement question

edited May 2018 in Health and Weight Loss
I've done my searches of previous posts on this topic but not come across anything helpful. To answer the typical questions that come with this topic:

-I've been consistently eating well and exercising for ~ 3 months
-I get ~ 20-30g of fiber per day
-I drink about 100oz of water and unsweet tea a day, no soda
-I eat a mostly plant based diet
-I've been to the doctor and they can find anything wrong

So anyway, when I eat a diet rich in vegetables, fruit, whole grains, nuts, etc, I get really messy BM. Not diarrhea, but so soft and loose it's really difficult to pass and I need a lot of wiping. There's no pain. Whereas, on the occasions when I eat something that's fast food or go out to dinner, my BM is much more solid and comfortable.

Does anyone have an idea of what's going on with me? This doesn't seem normal and ideally it should be the other way around right?

    Maybe you need to cut down on the water and see if that can trigger loose bms. maybe eat more whole grains? if you feel it is a problem maybe seek professional help.

    I used to have this problem when I was an observant Eastern Orthodox Christian and would obediently go on a vegan diet for Lent. It took nearly the entire 40 days of eating like that consistently for my system to adjust. Probably your gut flora are simply better adapted to one diet than the other.

    Give some probiotics like a live culture yogurt a try.

    I was like that before my diagnosis of Systemic Nickel Allergy. Whole grains, nuts, pulses and chocolate are all really high in nickel so if you already have a problem with it, I.e. jewellery, watches etc cause contact dermatitis, then you might want to consider this as a possible cause. There are also other metal allergies that can be triggered by eating whole grains, nuts etc as these types of plants take up much more metal from the soil than others which is then deposited in the germ and husk.
    Another thing to consider with whole grains is that they contain enough phytic acid to cause malnutrition in the long term if they are not prepared correctly by overnight soaking, sprouting or fermentation. Phytic acid chelates essential minerals such as magnesium and zinc which are then excreted instead of absorbed. If you are low on certain minerals, it can affect the bowel function.
    A third thing to consider is how much of your plant based diet is cooked versus uncooked.
    Eating a large amount of uncooked veg increases peristalsis so food can pass too quickly through your system. Again, in the long-term this leads to bigger problems. Also, cooking veges and fruits breaks down the fibre which releases more micronutrients than if you ate it raw. It does destroy Vitamin C, but too much of that will give you loose stools as well.
    Finally, caffeine, nicotine and alcohol all speed up peristalsis so be wary of those.

    I'd look at the balance of fibre - perhaps you have too much insoluble fibre and not enough soluble fibre? (insoluble is good for getting things movingf, soluble is good for providing bulk)

    I'm similar. some days I eat over 40g of fibre mainly vegetables and have lose bowels, but when the fibre is from carbs like bread, pasta, rice etc my bowel movements are more solid.

    maybe you arent getting enough fat since fast food makes a difference in your BMs. not enough fat can also make constipation worse,or cause it in some people

    I agree that a lack of fat in your high veggie days may be the issue.

    See how you do if you add some avocado to the veggies.

    I have had a similar issue for the last couple of weeks, and your post gave me an idea. I went back to look at my diary and nutrition stats, and the last couple of weeks I have had more fiber than before. It’s just a hunch, but it matches my experience.

    If people want links and citations there’s an entire internet world. Go find them. I get sick of people wanting someone to prove their point.

    Opposite, actually. If you posit something you absolutely should acknowledge sources if you have any hope of persuading anybody to your view.

    too much fiber for some can cause constipation too. some have chronic constipation and changes in diet dont help,thats when they need to see a dr to see what is going on if they havent been to one already.
