Ketosis issue

Too many unknowns. How long have you been trying keto? Keto diets are moderate protein and high fat but people have a hard time doing that, eating a lot of fat that is and subsequently the extra protein just gets converted into glucose and obviously effect ketone levels. Fat should represent at least 70% of your calories, what yours? Where are you getting your protein, animal or plant and are you actually aware of all the carbs your eating? Not to mention Urine strips are not very accurate at the best of times. a breath meter is better but a blood meter is really the best way. And there's more, but I'll leave it there.

Now saying all that, most people doing keto and know they're consuming very low carbs don't really care or monitor their ketones, it's not about ketones it's about hormones and if your eating patterns changed to the point where hunger and desire for sugary foods and carbs in general are pretty much in the distant past and your losing weight or easily maintaining then really that's all that matters. If your ketone level are that important then wait a month, and recheck or get a blood meter. There's no magic, you will be burning ketones if you continue.

Urine strips detect acetoacetate which is only 1 ketone of the 3 that are produced and as your body becomes more efficient at using ketones then acetoacetate becomes more efficiently used and less shows up in the urine, and why urine strips are highly unreliable.

I've been on a keto diet for over a decade, and if I'm curious I'll use a blood monitor that monitors both glucose and ketone levels, they're cheap and suggest you get one and anywhere from 0.5–3.0 mmol/L for ketones typically indicates you're in nutritional ketosis.

Also if your checking the urine strips after a meal then generally that's when glucose is elevated from protein so it's important if your goin to test with a urine strip to do it about 1 hour after you wake up but before you have your first meal and the reason why you wait is because of the "dawn effect" where glucose is elevated from the body releasing cortisol, epinephrine, and growth hormone to help you wake up which increases glucose production, so don't do that either. The reason I asked where you were getting your protein is because all protein from plant sources come with carbs unless it's an isolate but you said you don't eat anything processed.

There's a few things that interfere with ketone production and why urine strips are pretty much useless. Exercise, especially intense temporarily raises glucose, stress, protein rich meals, plus certain processes require glucose like our brain, our red blood cells and our kidneys and when on a very low carb diet then a process called gluconeogenesis is activated, which on a low carb diet will be more active and increase the process of making glucose from non-carb sources like amino acids (from protein) and glycerol (from fat). The body regardless, needs 130 grams of glucose a day for the reasons I just specified and that is exactly what the USDA says is a minimum, coincidence, no, so that's going to be produced regardless even if you don't eat any carbohydrates and why urine strips are not reliable, i think I got my point across about urine strips, lol.

All the fluctuations are transitory, it's like weighting yourself every 6 hours and wondering why the shifts happen. If your actually very low carb, you will be in ketosis more often than not and Like I said it's not the ketones that are really facilitating weight loss,if that's why your doing it, it about the amount of calories (food) your consuming. Low carbs main benefit is the realignment of our satiety hormones and like I said if your getting by with your 14 to 16 hour fasts and you don't feel hungry then that is the priority you should be concerned with and not why you cycle in and out of ketosis. Also you didn't answer my question on what percentage your fat represents as a macro?
