@dietbepsi yay for judgement jeans, that's what I call mine, so much more accurate than scales!
Keto sticks and all the other urine testing sticks are notoriously unreliable. They are unstable, have quite a large tolerance built in and are only a snapshot of what's going on in your urinary system rather than what your body is doing. From a strict science, physiological point of view ketosis is often a short lived phenomena, it occurs soon after you have depleted glycogen and is the precursor for your body becoming fat adapted. However in popular literature the word ketosis remains. Long term fat adaptation is what we're after, the body learns how to use ketones properly and doesn't waste any. The longer you are low carb, the better your fat adaptation gets, the more your body prefers the energy source and with most people an infrequent carb indiscretion will not take you back to being a primary carb burner.

Try intermittent fasting to kick start your weight loss of you are experiencing plateau

Don't forget to measure yourself, if this hasn't been mentioned! The inches drop faster than pounds sometimes (did for me!), and can be great motivation to continue! So glad you have some results to see though! If these jeans already zip it's time for skinnier jeans You are ROCKIN it! Congratulations!!
