Are you eating too many calories? I believe there’s a metabolic advantage to keto, but of course you can still go overboard …especially with bullet proof coffee. I also believe that it can take time to improve insulin resistance and get levels low. If you’re still really insulin resistant then you won’t have much of a metabolic edge. I think it can take time and possibly fasting can help improve insulin resistance and other issues. A lot of people don’t worry about calories on keto due to satiety and potentially improved metabolic rate. However, if you’re super insulin resistant, you may not be naturally satiated or burning body fat well, so calorie deficit and fasting may be necessary. Gary taubes and dr. Fung will probably call BS on what i just said, but the idea that calories don’t matter at all is absurd. You can absolutely gain weight on keto. So, not losing…consider ditching the butter coffee…at least until your body is functioning properly. If you’re already eating below maintenance calories, give it time or start IF
All of this is assuming you are taking measurements or something as short term weight fluctuations are not necessarily conclusive, and the scale cannot differentiate between fat, muscle and water. I only mentioned the above statements because some people like to tell you to ignore the scale when someone is stalling long term and not making progress. They will tell you to throw away the scale and eat more bacon, but it might actually be useful to be realistic and offer real information
