I would avoid the mince. Try finding a cheap source of meat cuts, it doesn't matter what cuts they are, but you don't know what's in that mince. There could be other things added, or parts of the animal that are high in toxins and you wouldn't be eating them if the whole cut was presented to you. If you get a chunk of supermarket meat and have it at room temperature and without any additives, you will notice that some parts of the fat is tasty, but some isn't. Don't eat the parts that don't taste good. Those are likely cooked fats from grains and full of toxins. When you eat mince, you can't avoid eating this.

I would also tend to be careful with the organs, eating them sparingly, or avoid them altogether. Organs from animals that are fed an unnatural diet, given lots of chemicals and kept in unnatural conditions can be overloaded with toxicity.

Frozen foods are not ideal but if you know the source is good and free of toxins, I would prefer it over high toxin meat, or have some of both. Either way I would avoid the mince.

Are you eating a lot of salt? Try weaning yourself off of it if you are. See if reducing salt intake improves digestion. You may not want to go cold turkey because there will be withdrawal symptoms.

If you're can't digest fats, the fats should be coming out undigested. It's possible that your gallbladder is damaged and you can digest some fats, but not a lot. Keep in mind the gallbladder is used when you need to digest large amounts of fats, but small amounts can be digested even if you've had your gallblader removed. By the way, eggs do contain a sizable amount of fats in the yolk. This fat is easier to digest however, since it's already liquid. It could also be a stomach acid issue. If you have a stomach acid issue, you would want your foods ground down, in that case you could get a meat grinder or food processor, or just chew things very finely.

I don't know how the oxbile tablets are made but I wouldn't take anything made in a lab. Plenty of people use raw bile instead, maybe you could get a source of that. It's generally thrown away during slaughter and/or butchering. As for the beet kvass, I would not want to have that while having a meat meal, as that can interfere with digestion. See what happens if you eliminate the fermented cod-liver oil and clarified butter. Have raw butter instead.

Is your dad still an alcoholic or drug addict?

Btw, I would be very careful with doing high meat with anything but great quality sources of meat and organs. Fermenting something that's already toxic is dangerous.

How much do you weigh?
Given that you had been vegan before, you are likely very thin.
You say that you drink raw milk when you can get it. In your state, you should probably be drinking raw milk every day.
If you have trouble digesting it, you could try adding raw honey to the raw milk.
All tribes that eat only animal foods drink a lot of raw milk, except for the Eskimos but those eat nose to tail and mostly seafood instead. You don't do any of that.
Once you have enough raw milk, you could start adding raw eggs.
Wish you the best of luck.

Hi,
Yes, I have a couple of non-mercury ones, my dad has a couple of mercury ones still in...
I also have a deepish cavatie for which I'm taking fermented cod-liver oil and clarified butter, suggested by Dr Weston Price

sorry to hear... I would say fasting, or semi fasting could be one way to improve things. Meat in itself is not a magic tool that will heal everything, especially if it is low quality stuff.
Herbs, roots, etc can have a good and strong healing effect. We tend to forget that part, especially carnivores. But look at cats, they love to sample herbs and plants, because they know what their body needs.
Try to see the whole picture. And, not only what you eat, but also drinking water, exposure to other toxins, and electromagnetic pollution.
