Hi this is my first post. I started the CKD about 3 weeks ago. I saw results immediately the first week, and was positive for ketones in the urine within a few days of starting. The first weekend carb load went well, and the next week I was back in ketosis within a day or two. The next weekend carb load I went overboard, and I haven't produced a positive test strip since. The only change I've made to the keto-phase of the diet is adding sugar free Metamucil, which I read is acceptable on keto-diets. I got back on track immediately following my "bad" carb load, and the next carb load I stayed within my limits, but I'm still not seeing a positive strip. Any ideas as to why this is happening would really help. I just can't seem to wrap my head around it. I know some of you are going to tell me to stop the fiber and see what happens, but as I'm sure some of you experienced, not having a bowel movement for a week is about as unpleasant as it sounds.
