Struggling to get back into Ketosis

Hi,

I have lost 2.8kg roughly around 6 pounds in a week since doing keto, but I haven't been able to get back into it for 3 days, and I can see my weight slightly creeping up.

Intermitting fasting for 18 hours having a 6-hour window from 1 pm - 7 pm and 1.5 - 3L a day of water, with a first meal at 1 pm with MCT Spoon an hour before, that first meal is a Fish broth with Nutritional Yeast, Kale, Miso Soup spoon, Chia Seeds and Flax Seeds with some Mushrooms and Mackerel.

Apple Cider Vinegar afterward, Then 1 -2 Cups of Organic Matcha tea in the hours of 3-4. Then 6 pm final spoon of MCT. 6:50 Quarter glass of vinegar and then dinner would be steak cheese bacon avocado nuts and homemade no sugars or carrots coleslaw. Dinner would be a variation of that often times steak replaced with salmon.

I was in ketosis for about 3 days and felt absolutely fantastic, but without that energy, I have still managed to lose weight by simply just being in a keto lifestyle. I want to divide my body fat of 27.4 by half and then get it one 1/3 down to the 10s 11 levels and I know Excercise will be required for the final stage, however, I do want to continue being in ketosis, but I am not eating carbs but cant gets back into it.

The energy levels were nothing like I have ever experienced and wish to get back into it.

I am very strict but have been looking for sweet keto snacks which I Believe since I started buying these keto ready-made cakes, they are the reason I am out of ketosis. Also in addition to having too much protein.

I have been a lover of cooking all my life and all cuisine, so to restrict myself to a diet of a finite amount of products is okay because I can make something of the few however I don't think I can spend 6/7 days of my week eating Red Meat, Egg & Bacon & Cheese. I despise Cheese Egg and Bacon and when I do get back into it, I will not be eating those products as they simply make me sick. Dairy especially, but red meat is just something I want to frequent just once or twice a month. The diet is great for fat loss and weight loss but my god it can be so unappealing when the best foods are the least interesting to me.

The snacks I had are above I had one of them plus a quarter slice of their carrot cakes, I wish I could put photos in here it would make everything more understandable But I essentially think I'm eating too many safe keto snacks, and too much protein. 3KG In a week is great, I just want to be in actual ketosis so I have those energy levels again, and can continue to keep losing weight.

My ketone blood levels were from 1.5 to 3.6 when in Ketosis and now I am in 0.4 and 0.6 and I notice the considerable difference in energy, if cutting the carbs in sugars from the treats is the cause then I can do it as when I was consuming about 8 blueberries and a quarter bar of dark chocolate I was definitely in ketosis and was not dropping. 

Any help would be great!

Thanks
