A couple thoughts for you............eating Carnivore, and I mean strictly following the rules, is very hard. It's easy at first, but gets boring very quickly. But if you don't follow ALL the rules.......you're wasting your time. You also have to be mindful of the fact that just because you're limiting your food choices doesn't mean you can eat as much as you want. You're simply replacing the carbs you ate with meat. So eating a whole cow at one sitting isn't going to help you lose weight. Limit what you eat at each meal to a normal portion size and don't touch any carbs. Yes, there's ways to cheat on Carnivore, but the primary goal is to get the processed carbs out of your body. So if you don't lose weight initially, reduce the total amount of food you eat. Calories in minus calories burned determines your weight. Which means get active! Burn those calories as you ingest them.
I had a friend try Carnivore, but he ate like a glutton. It was hard to watch him eat. And he never DID anything except sit around and play on his computer. Once he started eating like a human being again, and got out and walked (and then ran) everyday the pounds fell off.
Being an ostomate means part of your bowels are missing............so be mindful of what your body can no longer absorb..........and supplement for that. Sublingual is best, but not everything comes in a sublingual form. Every ostomate should have their micronutrient levels checked at least once a year, and have their supplementation modified so they aren't deficient in any key nutrients. Same goes for you. Now go have a double cheeseburger (but just one) on me. Medium rare please.
