Half week fasting weird event

So I had a weird events with fasting this week so I started Sunday by the end of the day and it's after noon on Thursday and from last week I didn't actually lose weight kind of give it a little bit of time cuz I I think something's up with it so I'll remeasured but I like it's almost negligible I think it was a 244.6 last week and I got on the scale this week and I was 244.4 I've metabolically I don't even know how that's possible but I'm going to give it a little bit I'm going to extend the fast a little bit see if I have a bowel movement or something waiting but really unexpected normally it's been a pound or two the last few weeks doing half week fasting but I maybe it was I drink more fluid or something but yeah it's unexpected
