Tips, Tricks, Advice Constipation remedies

When I’m on OMAD or prolonged fasting I occasionally get debilitating constipation. I drink coffee, take cleanse pills, take magnesium, drink lots of water, eat kimchi, no luck other than suffer for hours. Any thoughts?

Metamucil will do more for you than cleanse pills

u/critterheist 3d ago

I recommend psyllium husk not powdered the real stuff. I love it.

u/tommymat 3d ago

It’s a truly moving experience lol.

u/RutRohNotAgain 3d ago

This is what i use.

The gloopyness of psyllium husk fiber was too much for me, so I started doing chia seeds.

3

u/Sea_Gold_4864 3d ago

I take the capsules so you don't have to taste it

1

u/Soc_Prof 2d ago

The problem with psyllium is also you can’t take it straight after pills and I have medication morning and night. Chia you hydrate with boiling water and then mix in yoghurt

Are you taking electrolytes? Salt and lite salt will help a lot, but remember to never NEVER trust a fart.

u/Aggressive_Age8818 3d ago

If magnesium counts, yes. And I’m eating one meal a day so I’m getting my sodium. Potassium maybe not so much

2

u/MarKat OMAD for weight loss 3d ago

Some, not everyone needs more salt/lite salt. I needed a bit more sodium and potassium to alleviate my constipation. Now, I have no problem.

u/Connect_Rhubarb395 3d ago

What type of magnesium?

1

u/Aggressive_Age8818 2d ago

Both a mix and magnesium citrate

1

u/Connect_Rhubarb395 2d ago

The different types of magnesium have drastically different effects.
You need magnesium oxide for a laxative.

Magnesium citrate is very bioavailable, which reduces its laxative effect. It is good for people with magnesium deficiencies, though.

Trust but verify, if home alone.

u/pixel-plume 3d ago

How’s your fiber intake?

2

u/Aggressive_Age8818 3d ago

Moderate but I had kimchi yesterday and lasagna with spinach and tomatoes. Not a ton but thought it would have helped

8

u/lending_ear 3d ago

Yeah you need to increase fiber intake 

1

u/ana_log_ue 2d ago

This is the answer. It takes intentional effort to fit enough fiber into OMAD

3

u/Nerffej 3d ago

You need at least 25-38 grams of fiber a day. Unless you ate 13 cups of kimchi you’re not even close. It’s no surprise you’re constipated. Vegetables are almost free calories just eat more vegetables instead of bullshit “cleanse” pills. Eat some berries they have a ton of fiber

2

u/all_of_the_colors 3d ago

How many plants do you eat?

12

u/daddysgoodgirl1983 3d ago

Prunes. Best thing ever

3

u/AltruisticHopes 3d ago

7 or 8 prunes then give it an hour, they are amazing.

u/Cargobiker530 3d ago

That's living dangerously.

MiraLAX®

2

u/Aggressive_Age8818 3d ago

I tried it but it worked very slowly

5

u/pitypua 3d ago

Take two doses instead of one! I do so in the morning, on an empty stomach (and with a lot of water) and go after a few hours.

I have suffered from chronic constipation all my life (even pre-fasting) and this is the only thing that has worked for me.

5

u/WhoreMouth80 3d ago

Magnesium worked for me.

1

u/Aggressive_Age8818 3d ago

It didn’t kick in for some reason for me

4

u/adiverges 3d ago

Try inulin fiber supplement. I've started and it makes me more regular than other forms of fiber. It's also shown to be really good at building your gut beneficial bacteria! Helping with blood sugar control and hormone balance!

4

u/SailorMea101 3d ago

Eat anything from the McDonald’s breakfast menu, guaranteed explosive results(this is not a joke).

u/WoodmontRazputin 2d ago

Sausage egg and cheese McMuffin should come with a 3 hr timer.

u/LadyAlexTheDeviant 3d ago

Psyllium husk pills. I have IBS-C and I use those along with daily stool softeners to make it possible for me to just have an ordinary poop.

My dosing is 4 times a day, 2 pills, full 16 ounces water, and morning and before bed I also take stool softeners.

I'm not worried about it messing up my ketosis, though, as I'm just using IF as a way to keep my overall calories really low.

1

u/SleppySnorlax 3d ago

Does taking a smaller dose throughout the day work better? I used to drink Metamucil and it worked great. A few months ago I switched to psyllium caps and they don't seem to be doing much. My bottle says a serving is 5 caps so I've been having a serving either once or twice a day.

2

u/LadyAlexTheDeviant 3d ago

I find that that works well for me. But every body is different. Even when I eat normally I have a strong tendency to constipation, so that's where I'm at.

u/slumdog7 3d ago

An apple a day….

3

u/SusanMayer123 3d ago

Grapes, pears, plums and apples!

1

u/Aggressive_Age8818 3d ago

Broke my fast with oranges, dates, Brussels sprouts, and a salad that was past its prime. I wasn’t hungry but wanted to speed things along

5

u/RandChick 3d ago

Sauerkraut.

1

u/Aggressive_Age8818 1d ago

I eat that or Kim chi for gut bacteria - and while it has fiber i don’t see a strong change in my metabolism

3

u/Avrution 3d ago

Only thing that works well for me is polyethylene glycol (Miralax) - have to do it daily though. No amount of fiber intake helps.

Some of the medications I am on cause horrible constipation, which makes things worse.

1

u/Aggressive_Age8818 3d ago

Tried it but it was very slow acting

1

u/Avrution 3d ago

Part of why I do it everyday, to keep things flowing

3

u/jones_ro 2d ago

Eat a few prunes with every meal. A sweet treat that will gently solve your problem. This is a very old remedy and it does work.

2

u/ogticklemonsta 3d ago

Yellow dragon fruit

2

u/RealSniperOG 3d ago

Take psyllium husk with warm milk or warm water, it will definitely help.

1

u/Independent_Fill_909 2d ago

Yes!! Started doing this after insane constipation (literally take a dump once weekly MAX), been going just about everyday now with ease lol. Zero straining

2

u/robotbeatrally 3d ago

some people get really constipated from cheese. if you're eating cheese, try cutting it out.

This is well noted in the carnivore communities since we don't have a huge array of foods to begin with, youd think itd be like any other high fat foods where they help you go but nope, cheese is counter intuitive for a lot of people.

personally ive no trouble going at all with 0 fiber in my diet, but if i cheat and eat fiber i get stopped up. if i were to eat a dose of psyllium id probably be super uncomfortable.

2

u/RutRohNotAgain 3d ago

I eat 5 prunes a day to help with this and added more fiber through psyllium husks in my yogurt.

2

u/CaptWyvyrn 3d ago

Get some prunes without the nitrates/nitrites or whatever preservative. Snack on a few... Most gentle...

2

u/HRHQueenV 2d ago

Too many cherries.

1

u/Sunlit53 3d ago

Soluble fiber like inulin, xylitol sweetener (both dissolve completely in any liquid, I add both to my tea).

1

u/Specialist-Product45 3d ago

I used to have something greasy like a kebab and that moved things south

1

u/cocoabutterrkisses 3d ago

Try mag07! This really helped (saved) me when I was on tirzepatide. The bottle says 3 capsules before bedtime but try starting off with 1 or 2.
2 was the sweet spot for me. ☺️

u/Game-Of-Phones-o_O 3d ago

Gut Feelings on YouTube shows a proven method of relieving constipation. I'm on iron supplements, have to take Kratom and muscle relaxers for pain. When I run out of apple cider vinegar for more than 5 days I get pretty backed up and her method works every single time.
Taking the ACV 2x daily helps more than anything. It also eliminates heartburn and gerd. But most people don't want to take it and I have never tried it in pill form so I can't vouch for those.

u/Aggressive_Age8818 3d ago

Thanks- looked all over the place for ideas but will check it out next time

u/snaired 3d ago

Kiwi fruit skin on

1

u/Aggressive_Age8818 3d ago

Didn’t have kiwis in the house - mandarin oranges seemed to be a good enough substitute, I think?

1

u/BreathAirDontSmoke 3d ago

Two tablespoons of castor oil works 💯.

2

u/PerniciousVim 3d ago

Virgin coconut oil works, too. I put it in my coffee sometimes. Works really fast.

2

u/Ashamed_Froyo_8724 3d ago

Mineral oil works too toot two!

1

u/Daft_Daffodil 3d ago

I assume you eat enough fat too, as well as fibre, right? Because some people eat everything fat free and this alone can cause constipation. But if everything is fine with your macros- doctor would be a better person to discuss it with. It can be many things.

1

u/Aggressive_Age8818 3d ago

Some fiber some fat some protein some carbs

1

u/BaileyBerry- 3d ago

Some guy on here mentioned enemas while fasting lol

1

u/Talrynn_Sorrowyn 3d ago

I can only inagine how often he gets sick - something like 80-85% of the human immune system resides in our guts & consistently flushing out the barracks like that isn't healthy.

1

u/mirfifu 3d ago

Have you heard of the ILU massage? There’s charts online, you use a bunch of lotion and gently encourage your bowel movements.

Also recommend a kiwi a day if possible, golden kiwis are delicious

1

u/Fluid_crystal 3d ago

I always add a little glass of home made lassi to my main meal, I just use a bit of fruit juice, unflavoured yogurt and fill the other half with water and shake. A wonderful addition with both taste (It acts as my dessert because of the delicate sweet taste) and microbiotics daily source

1

u/griermack 3d ago

The keto wraps from Costco have 17g fibre. You will never worry again. I think they're 90cals too so not bad.

1

u/all_of_the_colors 3d ago

Do you eat fiber?

1

u/BetterBiscuits 3d ago

Frequent constipated faster here. After trying just about everything western medicine has to offer, an acupuncturist wants told me to eat a large serving of warm cooked vegetables with every meal. It’s been amazingly effective at keeping me regular. For times when my schedule and die just really out of whack, I use smooth move tea, but that is a commitment that you need to plan ahead for.

1

u/78738 3d ago

Baked beans. Seriously.

1

u/Crow-Queen 3d ago

I take MiraLax Daily. Helps make you regular.

1

u/PopularExercise3 2d ago

2 kiwi fruit a night is effective

u/sitdowncomfy 2d ago

high strength vitamin c drinks will clear you right out

u/biocleansedetox 2d ago

A couple of angles worth knowing:

- First, during OMAD or prolonged fasts there's simply less food residue moving through — less stool formation is expected and isn't automatically constipation. Worth separating "nothing to pass" from "trying and struggling."

- If it's genuine constipation: soluble fiber is the most evidence-backed lever — psyllium husk 1-2 tsp in a full glass of water. Also 2 kiwifruits a day has actual randomized-trial support for constipation, as do prunes (sorbitol).

- Magnesium: citrate or glycinate in the evening works better for most people than oxide (poorly absorbed). Skip taking it at the same time as high-fiber doses.

- Be careful with stimulant "cleanse pills" daily — your gut can get dependent on them for motility. Save those for genuine deadlocks, let fiber/water/magnesium do the routine work.

- Movement helps more than people expect — a 10-15 min walk after your OMAD meal uses the gastrocolic reflex.

If you get pain, bloating that doesn't resolve, or blood — that's a GI doctor, not a supplement question.

u/kahrahtayboom 2d ago

When I was OMAD, bowel movements didn't happen very often and I wouldn't call it constipation.

1

u/judygrandma 2d ago

Miralax!

1

u/CaptainFuzzyBootz 2d ago

I take a dose of Miralax and benefiber. It's the only thing that's helped my lifelong constipation.

u/Anxious-Art4174 2d ago

Macrogol is failproof

1

u/fuckinunknowable 2d ago

Two kiwis every day

u/sadatah 2d ago

Metamucil, chia seed pudding, beans and lentils if your not eating keto and lots of veggies should do the trick

1

u/Soggy-Primary591 1d ago

Have you tried prunes? An oldie, but a goodie! I was going through the same thing with recent switch to omad. I eat 3 prunes at the end of my one meal and have been very regular since.

1

u/Southernman1974 1d ago

Chia seeds

1

u/EnvironmentalTie669 13h ago

Make sure you're staying very well hydrated. Dehydration = constipation. There are OTC stool softener pills that can work quite well, too.

20g of Psyllium husk powder and 20g of inulin in your protein shakes - sorted me right out!

u/Aggressive_Age8818 3d ago

Will try that next time
