Welcome! You seem to be a nice person, you will fit here 
This is a great forum if you ask me.
Oh yes I almost never looked at keto recipes 
I have found frying up 600g nicely fatty meat makes a good base for my first meal… But it took time to get here (I started with vegetarian keto, still not too difficult but still, not nearly this simple or good) and it’s just the base, I complicate my meals to my heart’s content…
We have food threads, they don’t seem to have zillion ingredients even for the non-carni dishes
And can’t you keep some of your old dishes? I did that but it’s true I just halved my carb intake when I went keto, I already had low-carb recipes… My high-carb -> low-carb change was worse, I went paleo, vegetarian before and after and I had “what on earth can I eat?” moments… It’s way easier with meat and eggs. You even may grab a raw veggie with it, full meal. (Unless you are like me and dessert is mandatory but that can be super simple too.)
I don’t know why people try to stick to macros so much especially if they just get it from a guesswork, not their own experience… Not like experience is everything, we aren’t robots so we need different amounts of food on different days. Maybe not everyone but it’s very common and natural.
Eat enough protein and little enough carbs and don’t starve (and don’t overeat regularly but it doesn’t seem to your problem) but otherwise… You have nice ranges 
That’s good as I don’t think we can accurately track, I surely can’t, I don’t know the fattiness of my main food, meat, after all. And of course I can’t possibly know my energy need though I have an educated guess due to my experiences. Calculators always were off.
Other problem with the calculators that different people with the same stats and energy need may need a very different fat/protein ratio. I can’t get satiated without high protein but I shouldn’t eat tons of fat (I love both I like carbs the least, by far but I need a little here and there) so of course my fat/protein ratio shouldn’t be high. I overeat with 70% fat, almost no matter what. But I don’t focus on percentages, just the right, enjoyable, nutritious food I can eat enough from and what gives me great macros and satiation. It seems more natural and easier too. As I may not be able to track accurately (I do it still, it’s informative to some extent) but I feel what I feel.
IDK if the others wrote this already (probably, knowing them) as I just jumped into answering when I started to read your comment but don’t go to the gym for fat-loss. It may help but probably very little, many people experience no help or even a hindrance… And it’s much work for just losing a bit more fat, I think… Do it for pretty and practical muscles and better health and confidence!
(My last few years doing admittedly a bit half-hearted - I did what I could but it’s not enough - lifting did little, it had no impact on my weight and little on my muscles. Sigh. it’s hard work for a middle-aged woman with probably not so great genetics for it. but my weights still get bigger and bigger and when I won’t be fat, I probably will see some change, I only see the development of my biceps this far as my arms never were fat.)
But yes, it may help a bit. Especially when you actually get a significant amount of extra muscle mass. Your eating is still way more important but in some cases, it may be the extra push you needed I imagine looking at my experiences but they didn’t involve much fat-loss so it’s still a theory. I never will be able to prove it as my fat-loss is still mostly about how I eat, that will do most of the work - and I won’t test eating right without exercise as I need exercise. So you should do it for the other benefits hoping it helps with fat-loss too but main thing it shouldn’t hinder it…
And I just arrived at your questions.
- NO, it’s virtually never a good idea to starve yourself. Keto isn’t magic, you still need your nutrients and energy to function well…
One occasional day is fine (if you feel right). Some fasting is fine (if you feel right), even in the very beginning, why not if your body likes it? Especially if one is used to it, it’s probably much for the body to handle the new woe with a new fasting… I continued my IF on keto as IF is how I live, it’s the best for me by far. But one still eat well on IF… Just in a smaller window.
Fat is the lever, it’s fine to go somewhat low if you still get everything you need but it can’t be way too low as you can’t get much energy from carbs and protein on keto (and if you can eat insane amounts of lean protein, that still isn’t healthy).

OH SORRY I wrote too much while you are busy with the kids… I try to be more concise from now on but it’s super hard when I want to give info I collected during the years…
You food items look fine but you need fattier ones if you don’t get enough fat from them. (I could overeat fat from chicken and salmon myself, they aren’t lean. My chicken thighs with skin aren’t. But you probably don’t even eat really much of them.)
I don’t see why you couldn’t eat fruit… I ate banana nearly every day when I was a newbie and often 6 different fruits from my garden… Amounts matter… BUT if you are ABLE not to eat fruit without suffering, it’s great you don’t do it I suppose. Just like it’s great if you can not eating sweets. I half-lived on them at some point as it was my only way. Don’t force yourself too much but if it’s just some mild discomfort and inconvenience, it’s good if you learn to eat more proper food.
Meat is usually zero… Many cheeses are that too… Boiled eggs aren’t but it’s little and anyway, I consider animal carbs okay as my body told me so.
I personally eat when hungry, a proper meal, as much as needed.
If I just want to eat food while I definitely don’t need food… Well I actually try to avoid it with my big, satiating and satisfying meaty meals (they work) but if it still happens, it depends. If I am not committed to carnivore, it may be even sauerkraut, I love it in big amounts alone But that’s me. It’s individual. Some nice animal protein should be the best. Maybe fat. When I am still not fully satiated but I already had 160+ g protein, I often eat some butter, it may even help! And it’s a joy.
Some nuts and other oily seeds probably work for some people and totally not for others. And they have some carbs but it’s no problem when you eat, like, 5g of roasted peanuts and get satisfied… There are lower-carb seeds galore but I love peanuts.
- I never measured ketosis. I couldn’t find the strips anywhere but it’s fine. Just eat little enough carbs, that’s enough. Not like you know what is little enough when you start… I went as low as I could and then lower and my body told me what it liked. I don’t even care about ketosis, just feeling healthy and very well.
The usual advice should do for now: keep your carbs below 20g (I always use net as total never seemed to matter to me but if you can and want to be safe, try total) and get used to keto. If it works well, congrats! You can tweak things later, it’s the same with fat-loss, actually. Don’t hurry things, it’s a big change for your body. But eat enough, that’s important.
