I'm considering the carnivore diet strictly for health reasons (severe allergies, fat loss, hormone balancing).  It would involve the cessation of consuming anything not of animal origin and primarily eating only ruminants (beef and sheep).  I would combine this with intermittent fasting.

Is anyone aware of any teaching against this?  Is there any harm in eating meat on Friday for health reasons as long as nobody was scandalized by it? 

FYI...low calorie, keto, and "plant-based" all made me very ill.

I'm currently doing carnivore and specifically a very high fat, moderate protein version.  I'd say it's a lax version of BBBE because I do eat dairy. Although I prefer all variety that keto provides, after only 3 weeks of high fat no carb, my strength and vigor are back.  I had been lax with keto and boy it costs.  In a short amount of time on BBBE, minor hints of joint pain are gone. My energy is great.  My head is clear.  My sleep is fantastic.  My bathroom visits brief and without issue.  I also lost several pounds that had crept back on during keto.  Everything has improved for me.  I planned to quit at the end of October, but I may go another month because the benefits are that good. 

Yea, I didn't address the OP's concern in my last post, but really the only way carnivore would be wrong would be if one didn't observe regular fast and abstinence days or to do it strictly for self gain to the exclusion of the glory of God.  But then, all through my childhood and part way through adulthood, even though I was raised in a family of practicing Catholics, I never really did any kind of reasonable fasting or abstaining or glorifying God in my food life because years doing Novus Ordo practices hardly qualifies.  Ever since I've been keto and especially now that I'm carnivore, I observe fast/abstain days the traditional way and I actually find fasting and abstinence far more doable. As far as getting fiber is concerned, there are a lot of videos available on the subject from a carnivore perspective.  I was skeptical until did my own experiments, but the fiber hoopla is false.  Fiber is hard on the gut and unnecessary.  Even the biggest keto guy, Dr Berg, warns about fiber and even worse, grains.  I tolerate keto fairly well, allowing myself some fiber, but it wasn't until I cut out fiber and grains from my diet on carnivore, that I fully healed.  I will eventually go back to keto to get variety, but that's only because I can always return to carnivore and at times even BBBE to get to my healthiest self.  Most carnivore turned enthusiasts tried it for 30 days to see how well it works and many of them maintain it years later or return to it when necessary. What's really great about all of this is that you can gain control over food and health while figuring out what works best for you.     

My knee jerk reaction to this is: Yes, there is a problem with this. We abstain from meat on Fridays as a sacrifice to God, not a some quirky thing Catholics do for no reason. There is such an abundance of easily accessible food nowadays that "My tummy hurts when I don't eat meat" kind of seems like a wimpy excuse. It would be understandable if you lived in poverty and couldn't afford anything but meat, or had no access to anything but meat. I am unaware of the severity of your specific health problem that led you to this decision, but from what I understand, your excuse does not seem like a valid one that should prevent you from adhering to the Friday abstinence. I wouldn't recommend the weird vegan or keto stuff. Just make pasta, have a grilled cheese sandwich, or just stick with the fish. That's my advice, but God knows your situation better than I do. Viva Cristo Rey!

Thank you for your reply.  I prefer to fast completely on Fridays than to consume pasta, grilled cheese, or fish.  Besides it's more manly to fast than to eat kid food.  Have a great day!!!

The way the OP was written seemed to be asking if it was okay to eat meat on days of abstinence if that was deemed necessary for health reasons.  There was no mention of fasting in the OP so it shouldn’t be surprising that eating something besides meat, as opposed to fasting, was what was mentioned by some.  I would assume, given the OP’s digestive issues as described, that consuming pasta or the bread typical with grilled cheese would not be good.  The OP did not respond when some wondered if he could eat fish on abstinence days (or in general).
 
I am very curious to know how pasta, grilled cheese, and fish are “kid food” to be avoided by the “manly”.  Several of the Apostles were fishermen, and Our Lord multiplied the loaves and fishes (not loaves and beefsteak).  Were our Lord and the Apostles less than “manly” in some views here?
 
The appropriate answer to the original question is to ask a priest.  From my pre VII understanding (I was born I 1951) that is what one did as it is the Church which has the authority to establish disciplines and to grant dispensations (St. Matthew 16:19 and 18:18).  I don’t believe it has ever been Catholic practice for the laity to sit around the internet or some other venue and decide these things on their own.

As far as getting fiber is concerned ... the fiber hoopla is false.  Fiber is hard on the gut and unnecessary.

To each there own, but the above is definitely at odds with recognized and well established nutritional science.  It is also completely at odds with how my gut feels if I don't pay attention to having an appropriate amount and kind of fiber in my diet.

I quit eating red meat after watchingt this. I'm 64 and a few aches and pains went away. I did start eating anti-inflammatory foods and added a few anti-inflammatory suppliments as well. 



Talk to your doctor if you go ahead with that diet.

You could have eggs though, right?
