Oh, no problem, I like to write about myself and food 
No, why would I be bloated? It’s not much food, I need it. And I am healthy, I don’t think I am ever bloated, I am not even sure what that means. And it surely can’t happen from good food. I am a short female with some low-level activity (tiny walks, cycling, sometimes weightlifting but that’s negligible).
Building up to that amount… Not really but a bit, yeah, I did vegetarian keto (on/off) for years and then suddenly stopped eating plants and added meat… But my building up was for eating meat regularly. 600-700g beef or pork is really not much, it’s easy to eat, I could do it in the beginning, my average was very low though but I couldn’t get enough meat either so it’s hard to tell what was the reason. I personally like a lowish-meat carnivore, I don’t eat much meat in average but I have such meatier days regularly. I never did what many carnivore do (even women), 2-4pounds of meat every day - and never will, I suppose. But when I eat little meat, I eat 6-10 or more eggs, cheese, quark… I need my protein and nutrients and energy (fat is good for energy but only if I ate enough protein, 100-200g is nice for me for both macros).
This was a normal but still “high-calorie if want to lose fat” day. Around 2000 kcal.
I call my 1400-1800 kcal carnivore(-ish) days normal. It’s borderline impossible for me to go lower.
And I call my 2200-2500 days truly high-calorie, it happens here on there on carnivore (it’s higher if I raise my carbs, it was 4000 on high-carb and I did 3000 on my old keto). They are usually overeating days though I don’t really call them like that when it’s only a single day. My body has this pattern, I always had these stronger days here and there, it’s quite fine. Nowadays they happen when I make a nice roast after less meaty days. It’s a small wonder my 720g pork chuck roast day was lower (or not, it’s a way fattier chuck than usual so I can’t track reliably and I don’t really care. I actually don’t like or want tracking, it never helped me to lose in the last several years, it just gave me information - and some impressive numbers. I know eating 280g fat in a day, not regularly just sometimes is super easy on every woe I am willing to try even after a decade trying to keep my fat “low” and I don’t even feel it much at all -, I am a curious one. that’s why I do it sometimes now).
But my numbers are quite varied so I can’t say percentages, just what I wrote.
