While it sounds fast, it most likely is some water weight and won’t always be at this pace. It seems okay given all the factors.
The better question is how do you feel? Are you feeling tired and under nourished? Are you lacking energy? While fasting can leave you feeling that way for the first bit but you’ve been going a few weeks and if it’s continuously feeling “not great” it may be s but to fast, but if you feel okay, keet at it! :)
Based on your starting weight people do tend to lose more early on. Your numbers are very similar to mine. January 30 300.4 February 13 294.6 February 20 288.3. But for me I want the trend to last for as long as possible. Good luck
